Engine Specifications
The AGCO RT100A tractor uses a reliable diesel engine known for strong power and efficiency. This engine provides enough strength for demanding fieldwork and smooth operation during long working hours.
Engine Make & Model
The AGCO RT100A is equipped with a Sisu engine, specifically the Sisu 6.6L 6-cylinder diesel model. Sisu, now known under the AGCO Power brand, is recognized for making durable and efficient agricultural engines.
The Sisu 6.6L engine uses modern engineering to increase both reliability and fuel efficiency. Due to its straightforward design, you can expect easier servicing and regular maintenance.
Fuel Type & Emissions Tier
This tractor’s engine runs on standard diesel fuel, a typical choice for high-power farm machinery. Diesel engines deliver more torque at lower RPMs, which helps with heavy-duty tasks like plowing and hauling.
The AGCO RT100A was produced before the stricter emissions standards of recent years, so it meets the emissions regulations active at the time it was built. Typically, this means the engine falls under EPA Tier 2 regulations, which set basic limits for exhaust emissions of farm machinery in the early 2000s.
Cylinders / Displacement
The engine features six cylinders arranged in a line. This inline 6-cylinder setup helps increase fuel efficiency, reduce vibration, and deliver consistent power.
Engine displacement is 6.6 liters, or 6,600 cubic centimeters. Higher displacement translates into more overall engine power and the ability to handle heavier loads.
A 6-cylinder, 6.6-liter engine ensures stable performance even under heavy use.
Rated Horsepower (Gross & Net)
The AGCO RT100A offers 128 horsepower at 2,200 RPM on its engine rating. This gross horsepower number refers to total engine output before subtracting for losses from accessories, transmission, and other components.
At the PTO (Power Take-Off), the tractor claims 100 horsepower, which is the net power available to implements. Tested PTO ratings are often even higher, sometimes above 117 hp in lab conditions.
These numbers ensure you have sufficient power for attachments like mowers, balers, or tillers.
Summary Table: Rated Horsepower
| Measurement Type | Power Output | RPM |
|---|---|---|
| Engine Gross HP | 128 hp (95.4 kW) | 2,200 RPM |
| PTO (claimed) | 100 hp (74.6 kW) | – |
| PTO (tested) | 117.73 hp (87.8 kW) | – |
| Drawbar (tested) | 89.72 hp (66.9 kW) | – |
Peak Torque (Nm @ rpm)
The Sisu 6.6L engine provides high torque for demanding work. Peak torque figures generally reach above 500 Newton-meters (Nm) at moderate engine speeds.
You can expect strong low-end grunt, allowing the tractor to pull through tough conditions without excessive shifting or stalling. This is particularly important when handling heavy implements or working in soft soil.
Peak torque is delivered at an RPM range optimized for field use, typically between 1,500 to 1,700 rpm. High torque at lower speeds helps reduce operator fatigue and maintains fuel economy.
Compression Ratio
This model’s Sisu engine features a compression ratio of 18.5:1. Compression ratio is the ratio of the cylinder’s volume when the piston is at the bottom of its stroke to the volume when the piston is at the top.
A higher ratio like 18.5:1 means the engine compresses the air-fuel mixture more, increasing efficiency and power. This level is typical in turbocharged diesel engines, as it helps maximize power output per unit of fuel.
High compression supports reliable cold starts even in cooler weather. It also ensures more complete combustion, which boosts both performance and emissions control for engines in this class.
Cooling System & Capacity
The engine uses a liquid cooling system, important for maintaining safe operating temperatures during long periods of use. A liquid-cooled design helps prevent overheating, even when the engine is under heavy loads in warm climates.
This system circulates coolant through the engine block and head, dissipating heat through a radiator. Coolant capacity is matched to the engine size, usually holding several gallons.
Proper coolant levels and regular maintenance keep the tractor running efficiently and protect the engine from heat damage.

Power Take-Off (PTO)
The AGCO RT100A tractor offers a robust PTO system, designed for efficiency and reliable performance. Both horsepower and versatility in PTO operation make it well-suited for demanding farm tasks.
Claimed PTO Horsepower
You get a claimed Power Take-Off (PTO) horsepower of 100 hp (74.6 kW) on the AGCO RT100A. This means the tractor can deliver this power directly to PTO-driven implements, such as mowers, balers, and augers.
The tested PTO output can even reach slightly above the claimed value, helping with heavier loads or larger equipment. PTO horsepower is lower than the engine’s gross horsepower (128 hp), as some power is lost in transmission.
Rated PTO power is a critical factor when choosing implements, because the performance of tools like rotary cutters, grain augers, or hay balers depends greatly on this value. In real-world use, you need to match PTO horsepower requirements of your attachments to ensure smooth operation and prevent overloading.
PTO Horsepower Table:
| Tractor Model | Engine HP | PTO (Claimed) HP | PTO (Tested) HP |
|---|---|---|---|
| AGCO RT100A | 128 | 100 | 104.3 |
PTO Type (Independent / Live / Economy)
The RT100A uses an independent rear PTO system, making it simple for you to engage or disengage the PTO without stopping the tractor or even changing gears. This is possible due to a dedicated clutch for the PTO, separate from the main transmission clutch.
You’ll notice this type is preferred for modern row-crop tractors because it lets you operate PTO equipment while you slow down, stop, or maneuver the tractor, improving your efficiency during field work. Independent PTO systems are safer and offer more consistent power delivery compared to older live PTO or transmission-driven systems.
The independent PTO setup means you can connect and disconnect equipment quickly. This is especially useful when switching between tasks or frequently starting and stopping PTO-driven machinery in the field.
PTO Type Table:
| System Type | Description | Practical Benefit |
|---|---|---|
| Independent PTO | Dedicated clutch; operates separately | Engaged/disengaged anytime; easy operation |
| Live PTO (not used) | Runs through two-stage clutch | Requires partial disengagement of drivetrain |
| Economy PTO (N/A) | Lower rpm PTO for fuel savings | Not standard on RT100A |
PTO Speeds (540 / 1 000 rpm)
With the RT100A, you have access to two standard rear PTO speeds: 540 and 1,000 revolutions per minute (rpm). These speeds let you match the power output to a wide range of implements.
Many modern farm tools are designed for one of these two common PTO rpm rates. A selector lever makes it easy to switch between speeds.
The 540 rpm option is popular for smaller implements, such as post-hole diggers or small rotary cutters. The 1,000 rpm setting is used for larger, high-demand equipment like big mowers and grain augers.
You can run heavier attachments without sacrificing power or efficiency. Switching between 540 and 1,000 rpm is straightforward on the RT100A.
This flexibility allows you to maximize both fuel economy and performance while using various PTO-driven machines.
PTO Speed Table:
| PTO Speed Option | Typical Uses | How to Switch |
|---|---|---|
| 540 rpm | Small mowers, post-hole diggers, balers | Use selector lever |
| 1,000 rpm | Large mowers, grain augers, heavy tools | Use selector lever |
Transmission & Drivetrain
The AGCO RT100A uses advanced technology to deliver smooth power, easy control, and strong pulling ability. Each part of the drivetrain is designed for effective farm work and reliable road travel.
Transmission Type (Syncro, Powershift, CVT, HST)
The AGCO RT100A comes with a Continuously Variable Transmission (CVT). This CVT system, sometimes called a stepless gearbox, allows you to change speeds smoothly without shifting between fixed gears.
You benefit from seamless acceleration and a wide range of speeds. The CVT adjusts automatically, matching the engine’s power to the load and the work you are doing.
CVT transmissions are known for their ability to maintain optimal engine speeds and save fuel. This type of transmission also reduces fatigue because you do not have to shift gears frequently, especially during long operations.
Number of Gears / Ranges
Instead of standard gear sets, the CVT in the RT100A provides an infinite number of speed settings within its operating range. This means you have precise control from very slow creeping speeds to higher speeds for transport.
You don’t have fixed “gears” to worry about. The CVT lets you go as slow as you need for heavy-duty tasks or as fast as is safe with the same system.
This helps when matching implements or handling delicate work that needs steady movement. In traditional gear tractors, you often need to stop and shift, but with CVT, you can move from one job to the next smoothly without interruption.
Top Transport Speed
The RT100A’s CVT allows for higher road speeds than many older transmissions. The top travel speed for this model is usually around 25 mph (about 40 km/h), though actual speed might depend on local laws and tire type.
This high top speed helps you move quickly between fields or take your tractor on public roads without wasting time. When fully loaded, the CVT still manages to keep acceleration even and safe.
Drive (2WD / 4WD / AWD)
The AGCO RT100A is available as both a 2-wheel drive (2WD) and 4-wheel drive (4WD) model. For most heavy field work, the 4WD version is preferred because it gives better traction and power to all wheels.
You can choose the version that fits your needs. The 2WD works well for lighter field tasks or flat terrain.
The 4WD option is better for hilly land, muddy conditions, or pulling heavy loads. The 4WD RT100A increases performance in challenging conditions, reducing wheel slip and making work more efficient, especially when paired with the CVT transmission.
Differential-Lock & Final Drives
The differential-lock on the RT100A gives both rear wheels equal traction when driving through slippery or uneven ground. You can engage the differential-lock manually in tough spots and turn it off for easier steering when you return to normal conditions.
The final drives transfer power from the transmission to the wheels. They are built for long life and can handle the high torque this tractor delivers, especially in 4WD mode.
With these features, you reduce the risk of getting stuck and keep moving, even in muddy or rough fields. The final drives use strong components to withstand constant heavy loads.

Steering & Brakes
The AGCO RT100A uses a modern and responsive steering setup, paired with a dependable braking system designed for heavy-duty farm work. You get smooth handling and confident stopping power even when working in challenging field conditions.
Steering System (Hydrostatic / Power-Assisted / Mechanical)
You operate the AGCO RT100A using hydrostatic power steering. This means steering is assisted by hydraulic pressure, making it much easier to maneuver, especially at low speeds or when carrying heavy loads.
You do not need to put in much effort to turn the wheel, even with front-end attachments. The steering is precise and responsive, supporting reliable control in tight spaces or along uneven ground.
Hydrostatic steering reduces fatigue during long days. This system is nearly maintenance-free compared to older mechanical types.
Electronic controls help enhance safety and consistency. With hydrostatic power steering as standard, you are better equipped to manage sharp turns and fast adjustments when working in the field or navigating between rows.
Turning Radius (With Brakes)
Turning the RT100A in small areas is made possible by its responsive steering and brake-assisted turning. When you use the brakes in combination with turning, you can achieve even tighter turns.
This is especially useful for headland turns, narrow field entrances, or when maneuvering in confined barnyards. The specific turning radius will depend on whether you have the two-wheel-drive or four-wheel-drive variant, and on your brake usage.
Brake-assisted turning provides an advantage, helping you make sharper corners without reversing or multi-point turning. By applying the appropriate brake pedal, you can swing the rear of the tractor more quickly.
This gives you more flexibility and saves time in repetitive turning situations, such as plowing or working with hay equipment. The design improves overall maneuverability, making it reliable for a wide range of farm operations.
Service Brakes (Wet Disc, Dry Drum, etc.)
The AGCO RT100A is equipped with hydraulic wet disc brakes. Wet disc brakes are bathed in oil, which keeps the braking surfaces cool and reduces wear.
This setup offers dependable performance even after long hours and in demanding terrain. The hydraulic system provides a smooth braking response.
You can modulate the brake force easily, helping to prevent skidding and ensuring stronger control when moving heavy implements or loads on slopes. Wet disc brakes last longer than dry drum types because of their sealed, lubricated environment.
Maintenance needs are low, and you rarely need to replace parts unless the system develops a leak or severe contamination. These brakes are a key safety feature and help secure heavy machinery on uneven ground or loose soil.
Parking Brake Type
The RT100A has a mechanical parking brake system that holds the tractor in place when stationary. This brake is separate from the service brakes, so it remains effective even if there is hydraulic failure.
To engage, you usually lift or push a lever to lock the brakes. The mechanical design is simple and reliable.
It physically locks the drive wheels, preventing unintended movement on slopes or while parked with attachments. You can count on this parking brake in most farm settings or when you leave the tractor attended.
Regular checks are necessary to ensure that linkage, cables, and locking mechanisms are working correctly. Keeping the parking brake functional is important for operator safety, especially on inclines or during equipment hookup.

| Seat & Suspension | Adjustable suspension seat, ergonomic controls | Lower fatigue, smoother ride |
| Noise Level | Designed for low interior noise levels, insulated cab | Less operator stress, clear comms |
ROPS / Cab Option
You can choose between an open ROPS (Roll-Over Protection Structure) platform or an enclosed cab on the AGCO RT100A. The ROPS is a sturdy frame that surrounds the operator area, providing protection in case the tractor tips over.
The enclosed cab version adds another layer of safety, also giving you shelter from wind, rain, and dust. The cab doors and windows are tightly sealed, helping keep the interior cleaner.
For long days in the field, the cab gives you improved comfort, while the ROPS is useful for those who prefer more airflow or need to work in low-clearance areas. Both options are built to meet industry safety standards.
Climate Control (A/C, Heater, Filter)
Inside the enclosed cab, you get a climate control system with both air conditioning and a heater. The A/C keeps you cool on hot days, while the heater provides warmth when it’s cold outside.
Vents are placed throughout the cab for even air distribution. The system uses an advanced air filter, designed to catch dust and pollen.
This means you can work with the windows closed while still breathing clean air. Controls are easy to reach and allow you to set the temperature that feels right for you.
This lets you stay comfortable during any season, no matter what the weather is like outside.
Seat & Suspension
The seat in the AGCO RT100A cab is designed for comfort and support during long hours. It is cushioned, adjustable for height and tilt, and features a suspension base to absorb bumps from rough terrain.
Ergonomic controls let you find the best position with minimal effort. Armrests and lumbar support are included to help reduce back strain and fatigue.
Seat suspension helps keep your ride smooth over uneven ground. This attention to seating comfort means you can stay focused and efficient throughout your work.
Noise Level (dB A @ Operator Ear)
Noise levels inside the AGCO RT100A cab are kept low with insulation and careful design. The cab walls and doors have seals that block out much of the engine and transmission noise.
Sound levels at the operator’s ear remain within a comfortable range, allowing you to talk on a radio or phone without shouting. Less noise also means less operator fatigue, especially during long shifts.
For those choosing the ROPS version, noise may be higher since there is less sound insulation and more exposure to outside sources. Ear protection is recommended if working in loud environments.
Hydraulics
The AGCO RT100A tractor uses a closed-center, load-sensing hydraulics system. This allows for efficient power delivery, strong implement response, and steady operation for various attachments.
System Type (Open-Center / Closed-Center / PFC)
The RT100A features a closed-center, pressure and flow compensated (PFC) hydraulics system. This means hydraulic pressure is maintained until a demand is placed on the system.
When you use an implement, the system provides both the pressure and flow required, no more or less. A closed-center PFC system reduces wasted energy because the pump only works when needed.
This can help save fuel and lower heat buildup during long work periods. Operators benefit from fast, dependable hydraulic response for tools like loaders, mowers, or plows.
You get more consistent performance under varying loads. Whether you operate a single cylinder or several at once, the system is designed to sense and supply what each function needs.
Implement Pump Flow (L min⁻¹)
The primary hydraulic pump for the RT100A delivers about 109.8 liters per minute (L/min), which converts to roughly 29 gallons per minute (gpm). This pump flow is higher than many tractors in its class.
With this rate, you can run large or demanding implements, including balers, multi-section planters, or hydraulic rakes. The robust flow supports smooth and quick operation of equipment even when using several hydraulic features at once.
This rate of flow helps reduce wait times when raising or lowering heavy implements. You’ll notice the difference most during jobs that need frequent hydraulic adjustments, such as loader work or row crop cultivation.
Steering Pump Flow (If Separate)
On some tractors, the steering system may have its own hydraulic pump. For the AGCO RT100A, steering is integrated with the closed-center hydraulic system and is hydrostatically powered.
This means you benefit from a steady supply of pressure to the steering system. The steering remains smooth and responsive, even if you are running multiple hydraulic tools at the same time.
There is no need to worry about sluggish response or heavy feel on the wheel due to the system’s capacity. If you often make tight turns, especially in loader or fieldwork, this makes daily operation more comfortable and precise.
Total Combined Flow
With a total combined hydraulic flow rate of 109.8 L/min (29 gpm), all hydraulic functions on the tractor can draw from this capacity as needed. The closed-center design ensures flow is split efficiently between steering and remote valves or implements.
Here’s how combined flow is divided:
- Steering uses a portion of the flow whenever you turn the wheel
- The remainder goes to remotes and lift circuits when needed
You can lift, steer, and operate an implement without performance loss or slowdowns. For multi-tasking jobs, this combined flow is especially valuable.
System Pressure (bar / psi)
The system runs at a maximum pressure of about 200 bar (2,900 psi). This high-pressure level ensures you get strong lift and force for heavy implements.
With the closed-center PFC system, pressure is instantly available on demand. You get smooth loader lifts, fast implement cycling, and steady down-force for tillage equipment.
Higher pressure also means you can use more powerful attachments or larger cylinders without overloading the hydraulic system. The tractor remains steady and safe, even when performing challenging jobs like subsoiling or heavy material handling.
Remote Valves (Number & Type)
The RT100A usually comes equipped with three or four remote hydraulic valves. These are selective control valves (SCVs), which let you run several implements at the same time.
The remotes are typically double-acting, which is needed for most farm implements. The valves are easy to reach from the cab.
You can use them for attachments like rear augers, hydraulic top links, or grain carts. Extra remotes can be added if your attachments require more connections.
The setup allows flexibility in managing multiple hydraulic circuits for different implements. This supports a wide range of field and loader tasks.

Three-Point Hitch (3PH)
The AGCO RT100A tractor uses a three-point hitch system designed for heavy farm work. This hitch type is important for lifting, controlling, and attaching various implements like plows, mowers, and seeders.
| Feature | Description |
|---|---|
| Hitch Category | Category 2 |
| Lift Capacity @ Ball Ends | ~6,000–7,000 lbs (varies by spec) |
| Draft / Position Control | Yes (usually both functions built-in) |
| Top-Link Sensing | No top-link sensing (typically) |
Hitch Category (1 / 1N / 2 / 3)
The tractor hitch on the AGCO RT100A is Category 2. This category is commonly used on medium and large tractors in the 80–150 horsepower range.
It features pins that are 1 inch in diameter and arms spaced 32 inches apart. Category 2 hitches handle larger and heavier implements than Category 1.
This allows you to attach a wider range of field implements, including heavy-duty tillers, planters, and medium plows. Category 2 is ideal for the RT100A tractor’s power level.
You will want to be sure your implements use Category 2 connections. Some implements come with conversion bushings, but using the correct category is safest and ensures better control.
Lift Capacity @ Ball Ends
The lift capacity at the ball ends refers to how much weight the three-point hitch can safely raise and hold at the rear arms’ end. On the AGCO RT100A, this capacity usually ranges from about 6,000 to 7,000 pounds, depending on configuration and hydraulic system health.
This higher lift capacity means you can operate large, heavy implements like big rotary cutters, mulchers, and chisel plows. Always check the tractor’s manual for exact capacity at the ball ends to avoid overloading.
The actual usable capacity is slightly less when lifting farther from the tractor’s center. Only attach equipment within the rated limit for safe operation and long machine life.
Draft / Position Control
The RT100A’s three-point hitch supports both draft and position control functions. These controls help you keep implements at a constant depth or height as you work in the field.
Position control keeps the implement at the height you set using the hitch lever. This is useful for mowing or operating above-ground tools.
Draft control adjusts the hitch automatically to keep your plow or tillage tool at a steady soil depth, even if ground resistance changes. Being able to use both controls gives you greater versatility.
Select draft control for field work such as tillage. Switch to position control for jobs like grading or mowing fields.
Top-Link Sensing (Yes/No)
The AGCO RT100A does not typically include top-link sensing in its standard three-point hitch system. Top-link sensing is found on more advanced tractors and allows for even finer draft control, especially for sensitive tillage.
Without top-link sensing, the RT100A uses lower link arms to measure draft force. For most implement work, this system is reliable and straightforward.
You will not need special sensors or electronic connections for top-link tasks. Top-link sensing is usually important only for high-end precision agriculture or extremely sensitive soil conditions.
| Subsection | Key Details |
|---|---|
| Hitch Category | Category 2, 1″ pins, 32″ spacing |
| Lift Capacity | 6,000–7,000 lbs at ball ends |
| Draft/Position Control | Both available; ideal for depth-height adjustments |
| Top-Link Sensing | No; uses lower link sensing for draft control |
Axles & Load Limits
You need to understand the axle specifications and load limits of the AGCO RT100A to make sure you operate it efficiently and safely on any job site. Properly following these limits prevents damage to the tractor and increases its lifespan.
Maximum Front-Axle Load (kg)
The front axle of the AGCO RT100A must handle a significant part of the tractor’s weight, especially during heavy fieldwork and with attachments. Although published data does not specify an exact maximum load, you should remember that front axle load limits are typically set by the manufacturer to ensure safe operation.
Staying within this limit is crucial when using heavy front-mounted implements or loaders. Exceeding this load can cause premature wear or failure of axles and steering components.
For similar tractors, the manufacturer often recommends not exceeding axle design loads, which might be between 3,500 kg and 4,000 kg for the front axle in this class. Always check the operator’s manual or contact a certified dealer for the exact value and never estimate based on tire ratings alone.
Use proper counterweights when necessary to help balance the load. Inspect the front axle regularly for signs of stress, especially after using heavy implements.
Maximum Rear-Axle Load (kg)
The rear axle carries the bulk of the tractor’s weight, particularly when using implements on the three-point hitch. There is no public information about the exact maximum rear axle load for the RT100A, but typical values in this category can range from 5,000 kg to 6,500 kg.
This axle supports the 3-point hitch system, which has a lift capacity of about 8,500 lbs (3,856 kg) at 24 inches behind the ball ends. If you exceed the rear axle load limit, you risk damage to the axle, bearings, and rear final drives.
To prevent overload, always account for the combined weight of the tractor, ballast, and any attached implements or trailers. Make sure the overall load, including fluids in tires or wheel weights, does not exceed the manufacturer’s limits.
Regularly monitor axle conditions, especially after heavy hauling or tillage.
Final-Drive Type
The AGCO RT100A uses a robust final-drive system designed for durability and effective power transfer. The final drive is typically an outboard planetary or inboard reduction system, both aimed at increasing torque and reducing strain on axle shafts.
A good final-drive system is essential for maximizing traction and extending axle life. The RT100A’s closed center PFC hydraulics and strong transmission work with the final drive to deliver consistent power under load.
Regular maintenance of this system helps prevent breakdowns and minimizes costly repairs. Proper lubrication and routine checks are needed to ensure gears and bearings inside the final drive remain in good condition.
If you use the tractor for heavy work such as pulling or deep tillage, these checks become even more important.

Tires & Track Options
The AGCO RT100A Tractor lets you fit your tractor for your specific tasks and field conditions. Different front and rear tire sizes are offered, and you can add optional kits that change floatation, traction, and ground pressure.
Standard Front Tire Size (Ag / Turf / Industrial)
On the AGCO RT100A Tractor, front tire sizes are built for your operation type—agriculture, turf, or industrial. For most row crop work, you will use agricultural front tires such as 14.9R28 or 380/85R28.
These provide good traction in tilled fields. If you work on grass or want to reduce ground impact, turf tires can be selected.
Sizes like 16.9-24 or similar may be available, offering wider tread to prevent damage. For industrial or utility work, industrial tread front tires with a heavier pattern improve performance on gravel or packed surfaces.
Make sure to match tire selection to your needs, as wider or different-tread options can affect steering response and fuel use.
Standard Rear Tire Size
The standard rear tires for the RT100A are larger than the fronts for good power transfer. Most common sizes are 18.4R38 or 460/85R38 agricultural tires, which handle heavy loads and provide grip.
These sizes are suited to fieldwork, towing, and ground-engaging implements. Turf rear tires in sizes like 21.5L-16.1 are sometimes available for sod farms or sports fields, letting you work without rutting or damaging the ground.
For heavy-duty uses, industrial rears may be fitted. The type you choose should fit both the size and the tread type needed for your environment.
Optional Duals / Tracks / Flotation Kits
You can equip your AGCO RT100A with aftermarket duals, tracks, or flotation options. Duals allow you to mount a second tire on each side of the rear axle, which spreads weight and improves traction in soft ground.
Track kits, while not standard, can be installed by specialty shops. These give even lower ground pressure and help you work in wet or sandy soils.
Flotation tires or kits come with extra-wide tires, reducing rutting and letting you operate on delicate surfaces. Options depend on your dealer or third-party suppliers.
Always check your tractor’s axle ratings and clearances before adding duals or tracks. Proper installation keeps you safe and protects your machine from stress.

Fuel & Fluids
Managing fuels and fluids is key to keeping your AGCO RT100A running strong. Each system uses different fluids and has specific capacities you need to know for proper care and operation.
Fuel-Tank Capacity
The AGCO RT100A is fitted with a large 70-gallon (265-liter) diesel fuel tank. This extra fuel storage helps you work long hours in the field without stopping to refuel too often.
The tank is made of durable material and is mounted safely to avoid leaks or damage during harsh use. A bigger tank can be especially important for heavy-duty tasks when the engine is running at higher power.
Keeping the tank clean and using quality diesel fuel reduces clogging or wear in the fuel system. Always check the fuel gauge regularly, especially during long workdays.
When filling up, make sure the fuel cap is tight to prevent water or dirt from getting inside. Clean fuel helps maximize both performance and engine life.
DEF-Tank Capacity (If Applicable)
The AGCO RT100A tractor does not use a DEF (Diesel Exhaust Fluid) system. DEF is a newer emissions technology found mostly in tractors built after the emissions standards changed in the late 2000s and 2010s.
Since your RT100A predates these changes, there is no tank to fill or maintain. You do not need to purchase, store, or monitor DEF for this tractor.
That makes regular maintenance and operation simpler compared to models that require DEF. Even though DEF is not needed on this model, remember to always follow all local rules for emissions and fuel quality to protect both the tractor and the environment.
Engine Oil Capacity
The engine oil system on your AGCO RT100A holds about 22 quarts (around 20.8 liters) of oil. The engine uses high-quality diesel motor oil recommended by the manufacturer.
Check the oil level before starting a new day of work, especially if the tractor is being used heavily or in very hot or cold weather. Change the engine oil and filter at regular intervals to prevent wear.
Fresh, clean oil is critical for the Sisu 6.6L, 6-cylinder diesel engine’s performance and lifespan. Always use the correct grade and specification of oil listed in the owner’s manual.
Avoid overfilling or underfilling, as both can hurt the engine.
Hydraulic/Transmission Oil Capacity
The hydraulic and transmission system on the RT100A can hold a large amount of oil, around 18-20 gallons (approximately 68-75 liters), depending on options or attachments. This system uses a combined reservoir, so the same oil supports both tractor hydraulics and gearbox operation.
Always use the fluid type recommended by AGCO for both safety and efficiency. Low or dirty hydraulic oil can cause slow lifting, noisy pumps, or even damage expensive internal parts.
Check the fluid level and condition regularly. If you notice leaks, address them quickly to avoid major repairs and maintain smooth operation in the field.
Fluid & Fuel Capacity Table
| System | Type of Fluid | Capacity | Key Notes |
|---|---|---|---|
| Fuel Tank | Diesel | 70 gal (265 L) | Check for leaks, keep cap tight |
| DEF Tank | N/A | N/A | Not needed on this model |
| Engine Oil | Diesel Motor Oil (per manual) | 22 qt (20.8 L) | Regular checks and changes important |
| Hydraulic/Transmission System | AGCO Approved Hydraulic Oil | 18-20 gal (68-75 L) | Use correct fluid, monitor levels and cleanliness |
Electrical System
The AGCO RT100A tractor uses a modern electrical system designed to support reliable operation and power its accessories. The arrangement includes a negative ground, a strong alternator, and a high-capacity battery with a solid cold cranking amp (CCA) rating.
| Feature | Specification | Notes |
|---|---|---|
| Ground Type | Negative | Standard for most tractors and equipment |
| Alternator Output | 120 amps (typical) | May vary by region or installed options |
| Battery Voltage | 12V | Compatible with modern tractor electrical systems |
| Battery CCA | 950–1000 CCA (typical) | High capacity for consistent cold starts |
Ground Type (Negative / Positive)
The AGCO RT100A uses a negative ground electrical system. Negative ground is the most common setup for farm tractors built after the 1970s.
A negative ground means that the tractor’s frame and chassis are connected directly to the battery’s negative terminal. This allows simpler wiring and safer operation.
Most electrical accessories you add or replace will be made for negative ground systems. This arrangement supports easier troubleshooting.
It’s also safer compared to positive ground, which is rare in equipment of this size and age. If you ever use a battery charger, always connect the negative clamp to the chassis for proper grounding.
Alternator / Charging System
The RT100A has a robust alternator-based charging system, keeping your battery topped up and electrical equipment running even under heavy load. The alternator is belt-driven by the engine, turning mechanical energy into electrical energy for the whole tractor.
Modern tractors like this use alternators instead of generators for charging because alternators are more efficient at low engine speeds. This means your battery charges well even if the engine is idling.
The alternator is usually mounted on the engine block, making it easy to check and service. Most RT100A models come with a built-in voltage regulator, which keeps charging voltage stable.
This protects electrical systems from overcharging and helps extend battery life.
Charging Output (Amps)
The RT100A’s alternator usually provides about 120 amps of output when running at full speed. Some versions may offer slightly different amperage, depending on the region or if optional equipment is installed.
A charging output of 120 amps is large enough to power standard lighting, cab electronics, and even some extra accessories like auxiliary work lights or aftermarket radios. It ensures your battery stays full during long days in the field, even with multiple systems running.
When maintaining the electrical system, check for secure alternator belt tension and listen for bearing noise. Regular checks help you avoid unexpected downtime due to charging issues.
Battery Voltage
The AGCO RT100A tractor uses a 12-volt electrical system, which matches the vast majority of farm tractors made since the 1980s. This system voltage is compatible with most attachments and replacement parts.
A 12V system allows you to use modern lighting, radios, GPS devices, and other electronics without worry. If you ever need to jump-start the tractor, you can use another 12V battery, making emergency starts safer and easier.
Make sure that any electrical upgrades, like switching to LED lights, are 12V rated to match the rest of your system.
Battery CCA Rating
The RT100A uses a large-capacity, heavy-duty 12V battery, usually with a CCA (Cold Cranking Amps) rating in the 950 to 1000 CCA range. This high CCA ensures reliable cranking, especially in cold weather or after the tractor has been sitting for long periods.
A high CCA rating is critical for tractors like the RT100A because diesel engines need a lot of power to start—especially when the engine or weather is cold. If you live in a harsh climate, using a battery in the higher end of the recommended CCA range ensures more consistent starts.
Always check the CCA rating printed on your battery if you need to replace it. Using a battery with a lower CCA than recommended can make starting difficult or even damage the starter motor.

Recommended Service Intervals
You should follow a routine service schedule to keep your RT100A reliable. Change the engine oil and oil filter every 250 hours or at least once a year, whichever comes first.
Check and replace the air filter as needed, usually every 200-300 hours or more often in dusty environments. Clean or replace the fuel filter every 500 hours.
Hydraulic and transmission oil should be replaced about every 1,000 hours. Grease fittings—like those on the front axle and steering—should be lubricated every 50 hours.
Check coolant levels weekly and flush the cooling system every 2 years. Always use parts and fluids that meet AGCO specifications.
Keep records of all services to help with warranty claims and resale.
Estimated Annual Maintenance Cost
You can expect to spend between $2,000 and $3,000 per year to maintain an AGCO RT100A if you use it about 700-800 hours each year. This estimate covers routine parts like filters and fluids, as well as tires, belts, and batteries.
Labor for mechanic work is included in this range if you use a dealership for all services. If you do basic maintenance yourself, you might save money.
Repairs from unexpected breakdowns or major components replacement can push costs higher. Prices may vary depending on your region, service provider, and equipment use.
Depreciation Curve (% Per Year)
The AGCO RT100A typically depreciates about 10% of its value per year over its first 5 years. The rate slows to 8% or less per year after that, as long as the tractor is kept in good working condition.
For example, a tractor bought new for $80,000 will be worth about $48,000 after 5 years if depreciation is 10% per year. Depreciation is fastest in the first 2-3 years, mostly due to the drop once the tractor is no longer considered “new.”
After 10 years, most RT100As keep about 35%-40% of their original value if well maintained. Keeping accurate maintenance records can help your tractor hold its value.
Fuel Consumption @ Rated Load (L hr⁻¹)
When working at full engine load, the RT100A typically uses between 18 and 23 liters of diesel fuel each hour. The actual amount depends on the specific task, terrain, operator habits, and how well the tractor is maintained.
Fieldwork with heavy implements may mean you are closer to the high end of this range. Light transport or lighter field tasks will use less fuel per hour.
Monitoring your fuel use can uncover issues like dirty filters or tire slip, which can waste fuel and money. Measuring average fuel consumption for your main activities lets you estimate total yearly fuel costs.
