Power Take-Off (PTO)
The AGCO RT120 features a robust power take-off system that supports a wide range of implements. Its PTO delivers strong horsepower, offers flexible connection options, and supports multiple speeds to match different farming needs.
| Feature | Details |
|---|---|
| Claimed PTO HP | 120 hp (claimed), 122.2 hp (tested) |
| PTO Type | Independent, Rear PTO |
| PTO Speeds | 540 / 1000 RPM |
| Front PTO | Optional |
| Control | Mechanical lever or electronic (model dependent) |
Claimed PTO Horsepower
The AGCO RT120 tractor lists a claimed PTO horsepower of 120 hp. This means you can expect the power take-off shaft to deliver up to 120 horsepower to your implements, such as balers, mowers, or sprayers.
On test stands, some reports show slightly higher results, with a tested PTO horsepower around 122.2 hp. This gives you some assurance that the machine can maintain strength under actual working loads.
PTO Type (Independent / Live / Economy)
The RT120 uses an independent rear PTO system, which allows you to control the PTO separately from the tractor’s main transmission. This type offers convenient operation because you don’t need to engage or disengage the main clutch to start or stop the PTO shaft.
The PTO is typically operated by a dedicated lever or control switch. This setup means you can power your implements while the tractor is stopped or moving, giving you more control and efficiency.
The rear PTO is standard, while a front PTO is available as an option for those who use front-mounted equipment. Independent PTOs are common on modern row-crop tractors and are preferred for their ease of use.
You can also find Economy PTO options on some models, which allow operation at reduced engine speed. This can be useful for light-duty work, helping to save on fuel and reduce wear.
PTO Speeds (540 / 1 000 Rpm)
The RT120 supports multiple rear PTO speeds: 540 and 1000 rpm. This dual-speed system allows you to match the PTO shaft speed to the implement’s requirements.
Many smaller implements and traditional farm tools use the 540 rpm shaft. More modern or high-capacity equipment often uses the 1000 rpm speed for greater power transfer and efficiency.
Switching between the two speeds is usually done by adjusting the PTO shaft or selector, depending on your implement. If you choose the optional front PTO, it may have different speed settings to fit front-mounted tools.
Transmission & Drivetrain
The AGCO RT120 comes with advanced features for smooth power delivery and traction. You get reliable performance in the field and on the road thanks to multiple transmission and drive options.
Transmission Type (Syncro, Powershift, CVT, HST)
The AGCO RT120 is equipped with a Continuously Variable Transmission (CVT), known as the PowerMaxx CVT. This transmission allows you to change speed seamlessly without the need to shift between set gears.
With CVT, you can find the exact speed needed for different tasks, whether you’re planting, tilling, or transporting. CVT systems like this use advanced hydraulics and planetary gear sets to provide smooth acceleration and efficient power transfer.
Unlike manual or Synchro transmissions, you never have to worry about grinding gears or losing momentum during a shift. This setup gives you full control with less effort, making long days behind the wheel less tiring.
Some models of the RT series are available with a 24-speed partial powershift or even a 32-speed partial powershift. The PowerMaxx CVT is especially valued for use in row-crop and heavy fieldwork because of its ability to maintain constant speed under changing loads.
Number Of Gears / Ranges
If your AGCO RT120 is fitted with the PowerMaxx CVT, you don’t select gears in the traditional sense. Instead, the CVT offers infinite speed choices within a set operating range.
This means you can smoothly move from a crawl to top speed without distinct gear steps. Other available transmissions include a 24-speed or 32-speed partial powershift.
These gearboxes provide several gear ranges, letting you shift through numerous gears within fast and slow ranges. The 24-speed partial powershift allows for semi-automatic shifts under load, making it easier to match your speed to the job without stopping.
Here’s a basic comparison:
| Transmission Type | Gear Count | Shifting Method |
|---|---|---|
| PowerMaxx CVT | Infinite (within range) | Stepless |
| 24-speed partial powershift | 24 | Semi-automatic |
| 32-speed partial powershift | 32 | Semi-automatic |
Top Transport Speed
The top transport speed of the AGCO RT120 tractor can reach around 25 mph (40 km/h), depending on tire size and transmission setup. The CVT makes it possible to maintain any speed up to this limit, which is useful if you need to travel long distances between fields or along public roads.
A higher transport speed reduces the time you spend moving from one location to another, increasing your productivity during the busiest seasons. This speed is competitive for its size class and matches or exceeds many similar tractors.
You have the ability to precisely control low speeds for implement work, but you can also reach max speed quickly and comfortably for highway driving. This flexibility is an important reason why CVT tractors are preferred for both farm and transport work.
Drive (2WD / 4WD / AWD)
The AGCO RT120 is available in both 2WD and 4WD (all-wheel drive) configurations. Most users choose the 4WD version, as it offers better traction and stability—especially in soft or muddy fields, hilly terrain, or when pulling heavy implements.
With 4WD, power is delivered to both front and rear wheels. This feature helps you avoid getting stuck in wet soil and ensures smooth operation during tough field conditions.
If you plan to use your RT120 mainly for light transport or on paved surfaces, 2WD can be an option. For heavy fieldwork and all-season use, 4WD is recommended.
The 4WD system can usually be engaged or disengaged as needed. This lets you switch between modes if you want to save fuel during lighter work or on dry ground.
Differential-Lock & Final Drives
The differential lock on the AGCO RT120 helps you keep moving in slippery conditions. When engaged, it locks both wheels on the same axle together, so they turn at the same speed.
This is important if one wheel starts spinning in mud or on loose soil. Engaging the lock gives you extra traction until you get back on firm ground.
Most controls are foot or hand-operated for quick use when needed. Some RT120 models come with automatic differential locks that engage and disengage based on wheel slip.
The final drives on the AGCO RT120 use heavy-duty gears and axles. These are designed to handle the high power output without excessive maintenance or failure.
Robust final drives ensure effective transfer of engine power to the wheels, especially under heavy load and over rough terrain.

Steering & Brakes
The AGCO RT120 tractor uses a combination of advanced steering and robust braking systems to provide better control and safety. You get systems designed for easy handling in the field, along with reliable stopping power in a range of conditions.
Steering System (Hydrostatic / Power-Assisted / Mechanical)
The RT120 is equipped with a hydrostatic power steering system. This system uses hydraulic power to make turning the steering wheel much easier, especially when you are operating at lower speeds or moving heavy loads.
Hydrostatic steering allows precise control with less effort from you, which is essential for tasks like row-crop farming or tight maneuvering. You do not have to worry about old-fashioned mechanical or manual steering fatigue with this model.
Power-assisted steering also reduces wear and tear on your arms and shoulders after long hours in the cab. The system is designed to adapt to different driving conditions, maintaining steady and smooth performance on rough and uneven ground.
Hydrostatic steering makes it possible for you to turn the tractor with accuracy even while stationary or moving at low speeds. This is especially beneficial in confined spaces.
Turning Radius (With Brakes)
The turning radius of the AGCO RT120 is designed to be tight enough for you to maneuver easily in smaller fields or around obstacles. When using the brakes in combination with the steering system, you can make even sharper turns.
This is known as “brake-assisted turning.” By pressing one of the individual brake pedals, you can slow down just one of the rear wheels.
This allows the tractor to pivot more sharply around the slowed wheel, reducing the overall turning radius. This feature is helpful when you need to line up precisely at the end of a row or navigate around tight corners.
While direct specifications for the turning radius vary based on tire size and wheelbase, the addition of brake-assisted turning gives you greater flexibility during fieldwork. This precise handling is a major advantage when working in layouts with lots of obstacles or narrow headland spaces.
Service Brakes (Wet Disc, Dry Drum, Etc.)
The AGCO RT120 comes standard with hydraulic wet disc brakes. Wet disc brakes are sealed in oil, which keeps them cool and clean.
This reduces brake wear and gives you more consistent braking performance, even when operating under heavy loads or on slopes. Hydraulic actuation means that braking power is applied evenly to all wheels, which improves your control and safety.
Wet disc brakes need less frequent maintenance than dry drum brakes, which can be affected by dust and dirt buildup. These brakes are especially useful during repeated stops or when you are descending hills with heavy implements.
The sealed system also protects against moisture and mud that can compromise other types of brakes. This reliability is important if you regularly work in damp or uneven fields where traction can change quickly.
Parking Brake Type
Your AGCO RT120 uses an independent parking brake system, typically engaged by a hand lever within easy reach inside the cab. This system is designed to keep the tractor securely in place when parked, even on inclines.
The mechanism often connects directly to the rear wheels through additional wet disc assemblies or an integrated locking system. When set, it locks the tractor’s movement completely, giving you peace of mind when leaving the machine unattended.
The independent design also means you can set the parking brake without relying on the service brakes, ensuring there is no hydraulic pressure loss over time. Regular inspection of the parking brake linkage is important for reliable operation, especially if the tractor is parked on uneven ground or near machinery.

Cab & Operator Station
AGCO RT120 tractors place a strong emphasis on the comfort, safety, and control of the operator. Features in the cab are designed to improve your working conditions during long hours in the field.
| Feature | Description | Benefit |
|---|---|---|
| ROPS / Cab Option | Enclosed cab or open ROPS | Safety, Operator Preference |
| Climate Control | Air conditioning, heater, cab air filter | All-weather comfort, Clean air |
| Seat & Suspension | Adjustable seat, suspension system, ergonomic controls | Reduced fatigue, Comfort |
| Noise Level | Approx. 78-83 dB(A) measured at operator’s position | Less stress, Easier communication |
ROPS / Cab Option
You can choose between an open ROPS (Roll-Over Protective Structure) or a fully enclosed cab on the AGCO RT120. The cab is built with strong materials for safety in case of rollover.
An enclosed cab gives more protection against weather, dust, and noise. If you choose the ROPS configuration, you get an open-air experience.
This setup offers more visibility and airflow but less protection from rain or extreme temperatures. Both options come standard with safety features such as seat belts and easy exit points.
The cab version is usually preferred for longer work periods and harsh weather, providing a more comfortable environment throughout your day.
Climate Control (A/C, Heater, Filter)
Inside the enclosed cab, you will find a complete climate control system. The air conditioning helps keep you cool in hot weather, while a strong heater provides warmth in colder months.
The system uses a cab air filter to reduce dust, pollen, and other particles from getting inside. Air vents are placed for even airflow, so you get comfort no matter where you sit in the cab.
You can adjust the temperature to your liking with user-friendly controls. Even in areas with extreme weather swings, this climate control system helps you stay comfortable so you can focus on your work.
The cab filter should be checked and replaced as needed for the best air quality. Proper maintenance keeps the inside of your tractor clean and comfortable, improving your health and work results.
Seat & Suspension
The operator seat on the AGCO RT120 is built for comfort and support. It includes an adjustable suspension system to reduce bumps and jolts when driving over rough fields.
You can move the seat forward, backward, up, or down to match your size and preferred driving position. Armrests and lumbar support are available to reduce fatigue on long days.
Controls for the tractor are within easy reach, so you can make quick adjustments without straining. The steering column often tilts and telescopes, letting you set it for your comfort.
Noise Level (dB A @ Operator Ear)
Noise levels in the AGCO RT120 cab usually range from 78 to 83 decibels at the operator’s ear, depending on engine speed and load. The enclosed cab includes insulation and tight seals that reduce noise from the engine and field equipment.
Lower noise makes it easier for you to communicate with others by radio or in person. Hearing protection may still be recommended for all-day use, especially at higher engine speeds.
The ROPS model is generally louder because it lacks insulation. Longer exposure to high noise may cause fatigue, so choosing the cab version can help ensure you work in a quieter space.
Hydraulics
The AGCO RT120 uses a modern hydraulic system designed for both efficient power and precise control. Key specs like system type, flow rates, pressure, and valve setup all play an important role in how you use implements and attachments.
System Type (Open-Center / Closed-Center / PFC)
This tractor features a closed center, pressure flow compensating (PFC) hydraulic system. In a closed center setup, hydraulic fluid does not flow constantly; instead, it is pressurized and only moves as needed.
The PFC aspect means the pump responds to demand, maintaining pressure but saving on energy when the full flow isn’t needed. This setup offers you quicker and more efficient response for hydraulic implements.
It reduces wasted energy, leading to less heat buildup and lower fuel consumption. Closed center PFC systems are also quieter and last longer compared to older open center designs.
Implement Pump Flow (L Min⁻¹)
For the RT120, the primary implement pump delivers strong flow rates to your attachments. With a maximum implement pump flow typically around 98-110 liters per minute, you have more than enough hydraulic power for most row-crop and loader work.
Higher flow rates ensure that cylinders extend and retract quickly under load, so tasks are finished faster. This flow rate also allows you to run multiple hydraulic functions at the same time, useful if you need to raise an implement while adjusting another.
For heavy implements—such as big planters or front loaders—the high flow prevents slowdowns and keeps performance predictable. Your attachments respond promptly to every control input.
Steering Pump Flow (If Separate)
The steering system on the RT120 tractor is separate from the main hydraulic pump, using its own dedicated hydrostatic pump. This design ensures consistent steering response, even if other hydraulic functions are demanding high flow.
A separate hydrostatic power steering pump means steering remains easy and predictable regardless of what the implement circuit is doing. In fieldwork or transport, your steering wheel effort stays light, so fatigue is reduced, and safety is improved.
Even at slow engine speeds or heavy hydraulic load, you never lose effective steering power.
Total Combined Flow
By combining the implement pump and steering pump, total hydraulic flow available is significant. On the AGCO RT120, you may see a total combined flow of up to 120 liters per minute (implement plus steering).
Having a high total flow is important when running many hydraulic functions together. For example, when pulling a complicated planter with several hydraulic motors and also using the loader or lift, you don’t lose performance in any area.
| Feature | Specification |
|---|---|
| System Type | Closed Center, Pressure Flow Compensating (PFC) |
| Implement Pump Flow | 98 – 110 liters/minute |
| Steering Pump Flow | Hydrostatic (separate), approx. 20 liters/minute |
| Total Combined Flow | Up to 120 liters/minute |
| System Pressure | 200 bar (2,900 psi) |
| Remote Valves | Up to 4, double-acting with ISO couplers |
System Pressure (Bar / Psi)
The RT120’s hydraulic system is built to handle demanding jobs. Maximum system pressure is 2,900 psi (200 bar), which allows the tractor to lift heavy implements, run large cylinders, or operate hydraulically-powered motors without trouble.
This high pressure gives you more force when using hydraulic equipment. The system is designed with built-in relief valves to keep pressure within safe limits and protect both the pump and your attachments.
Remote Valves (Number & Type)
The RT120 can be fitted with up to four rear remote valves. Each remote is double-acting and uses standard ISO-style couplers so they work with most farm attachments.
These valves control functions like raising/lowering implement cylinders or adjusting hydraulic motors. More available remotes mean you can connect several implements at the same time without switching hoses.
The double-acting design means you can supply pressure to both extend and retract functions on your implement, giving you full control for operations like loader work, adjusters, or splitters. Remotes are usually operated by easy-to-reach levers or fingertip controls in the cab.
| Subtopic | Main Feature | Benefit to You |
|---|---|---|
| System Type | Closed Center, PFC System | Efficiency and fast hydraulic response |
| Implement Pump Flow | 98-110 L/min | Faster implement movement |
| Steering Pump Flow | Separate hydrostatic pump | Steering stays reliable under heavy load |
| Total Combined Flow | Up to 120 L/min | Multiple hydraulic functions at once |
| System Pressure | 2,900 psi (200 bar) | Handles large implements with ease |
| Remote Valves | Up to 4, double-acting, ISO couplers | Connect/control several attachments easily |
Three-Point Hitch (3PH)
The AGCO RT120 tractor is equipped with a robust three-point hitch system. It provides versatile implement handling, strong lifting capacity, and precise control for a range of field tasks.
| Feature | Specification/Detail |
|---|---|
| Hitch Category | Category 3 |
| Lift Capacity @ Ball Ends | ~8,000–9,000 lbs (varies by specific configuration) |
| Draft / Position Control | Electronic, with adjustable position and draft |
| Top-Link Sensing | Yes (supports draft control functions) |
Hitch Category (1 / 1N / 2 / 3)
The AGCO RT120 uses a Category 3 three-point hitch at the rear. This hitch type works with larger implements designed for mid- to high-horsepower tractors.
You can attach large plows, heavy cultivators, and broad tillage equipment. Category 3 pins are 1-1/4 inches (32 mm) in diameter, and the link spacing is wider than Category 2.
This means you can move heavier loads and connect to commercial-grade equipment used in row cropping or hay production. Unlike smaller tractors, a Category 3 hitch allows you to use attachments with higher power requirements.
Lift Capacity @ Ball Ends
Lift capacity at the ball ends for the AGCO RT120 falls around 8,000 to 9,000 pounds. This rating measures the strongest point of lift, where the implement attaches to the hitch arms.
You can safely handle most large rear-mounted implements such as heavy mowers, multi-row planters, or large fertilizer spreaders. If you use drawn implements, the tractor’s drawbar rating supports pulling wide equipment in demanding conditions.
The combination of strong rear lift and pull force lets you perform deep tillage or lift large pieces of equipment without worry about hydraulic strain. The higher lift capacity means you are less restricted by the weight of compatible implements.
Draft / Position Control
The RT120 gives you electronic draft and position control for the rear hitch. Position control lets you set the specific height of the attachment, so you can maintain even working depth across the field.
Draft control, supported by sensing systems on the hitch, automatically adjusts the hitch height in response to changing soil resistance. This keeps implements at a constant depth, improving traction and reducing engine load.
You can fine-tune both functions with in-cab controls. These systems work together to help you get smooth, efficient results and prevent damage to your tractor hitch or mounted tools.
Top-Link Sensing (Yes/No)
The AGCO RT120 comes equipped with top-link sensing as standard, allowing real-time draft control. With a sensor in the top link, the tractor can accurately detect changes in load and soil conditions.
This information lets the electronic control system make instant adjustments. With top-link sensing, the draft system reacts faster to rises or dips in ground resistance.
This keeps the implement level and lowers the chances of wheel slip or uneven depth, especially in difficult ground. You do not have to keep making manual corrections.
Top-link sensing supports efficient fieldwork, helps extend the life of rear implements, and reduces strain on your tractor frame and lift arms.
Axles & Load Limits
You need to understand axle capacities, load restrictions, and drive design to make sure the AGCO RT120 tractor works safely and effectively in the field. Knowing these details helps prevent equipment damage and supports long-term reliability.
Maximum Front-Axle Load (Kg)
The front axle needs to handle much of the tractor’s weight, especially when lifting heavy implements. For the AGCO RT120, the maximum front-axle load is approximately 3000 kg.
This means you should not exceed this weight on the front axle to avoid stress that can cause wear or failure. Attaching front weights or heavy loaders adds extra force to this section of the tractor.
Keep in mind that tire inflation should also be monitored and kept at the recommended pressure (typically around 160 kPa) to support this load. If you frequently use front-mounted equipment, check axle and tire condition often.
Overloading the front axle can result in steering problems and increased maintenance costs.
Maximum Rear-Axle Load (Kg)
The rear axle on the RT120 supports the majority of field implements and the bulk of the tractor’s power transmission. Its maximum load is generally rated higher than the front.
The rear axle load limit on the AGCO RT120 is about 5000 kg. This higher limit allows you to use heavy three-point hitch implements, large planters, or significant towed loads without over-stressing the rear components.
Proper ballasting and weight distribution remain important to keep the rear wheels grounded and maintain stable traction. Monitor axle hubs and rear tires for signs of excess stress, like abnormal wear or overheating.
Exceeding the rear axle load can cause premature failures or even axle breakage.
Final-Drive Type
The AGCO RT120 features a planetary final-drive system. This design uses a combination of gears to distribute the engine’s power efficiently to the wheels.
Planetary drives are known for being strong, dependable, and able to handle high torque from the 6-cylinder Cummins engine. You benefit from improved durability with this setup.

Tires & Track Options
Tire and track options on the AGCO RT120 play an essential role in how your tractor performs in different field and work conditions. The right choice can improve your traction, reduce soil compaction, and even lower your fuel costs.
Standard Front Tire Size (Ag / Turf / Industrial)
The AGCO RT120 usually comes with standard front agricultural (Ag) tires sized around 14.9R28. These provide strong grip for fieldwork and paddock use.
For use on lawns or sports turf, you may opt for turf tires in sizes like 380/70R28, which are wider and designed to reduce marks and ground disturbance. Some operations need industrial tires.
These are often in the size range of 12.5/80-18. They work better for mixed-use tasks, such as loader work and road transport because they have a tougher sidewall and different tread pattern.
All three types are tubeless for easier repairs and better performance. Proper inflation is important for each type.
Ag tires may need to be set lower for field use, while industrial and turf options need higher pressures for carrying loads on hard surfaces. Be sure to check your manual for the correct PSI for the front tire type you choose.
Standard Rear Tire Size
For the rear wheels, the most common Ag tire size is 18.4R38 or 480/80R38. These tires help transfer the RT120’s horsepower to the ground, especially important for heavy field tasks like plowing or tillage.
Wider tires like 520/85R38 are available for additional floatation, which helps in softer soils. Rear turf tire sizes are typically wider, for example, 520/70R38.
These distribute weight better when working on turf and reduce ground damage. If you require versatility, industrial rear tires often come in similar sizes to the front, like 18.4-38, but feature heavier construction.
Load capacity should match your maximum expected rear ballast and implements. Improper fit or a mismatch between front and rear sizes can lead to drivetrain wear or reduced performance.
Optional Duals / Tracks / Flotation Kits
Dual wheels can be fitted on both front and rear axles for better traction and stability, especially in soft or muddy fields. They are often used for heavy tillage or where slip must be minimized.
Installation typically requires wheel spacers or hubs, which must be compatible with the RT120’s axle specs. Track conversion kits are becoming more common, especially in high compaction or wet soil zones.
Aftermarket kits allow swapping standard wheels for rubber tracks, which increase floatation and reduce rutting. Tracks are recommended for certain crops and when you need to avoid sinking.
Flotation kits may include extra-wide tires or special rims, further reducing ground pressure. You can order these kits as factory options or through aftermarket suppliers.
Matching these kits to your intended use ensures you get the maximum benefit in tricky field conditions.
