Transmission & Drivetrain
The AGCO RT140 offers reliable power transfer, multiple gearing options, and a strong drive system for demanding work. Features like a robust transmission and choice of drive types help ensure traction and ease of use in a variety of tasks.
Transmission Type (Syncro, Powershift, CVT, HST)
The AGCO RT140 uses a continuously variable transmission (CVT). CVT systems allow you to select any speed within the operating range smoothly.
There are no fixed gear steps, allowing you to find the right speed for the job. This CVT uses advanced hydraulics for seamless shifting.
It is designed for tasks where precise control and variable speeds are important. You do not need to stop or clutch to change speeds.
The transmission is controlled by a simple lever or dial. The automatic nature of CVT can also help reduce operator fatigue.
Number of Gears / Ranges
Since the RT140 has a CVT, you do not work with traditional gear numbers or shift ranges. Instead, you can move from minimum to maximum speed fluidly.
The entire speed range is available at any time, so there are no ‘gaps’ between gears. Older tractors use fixed speeds with set gear ratios.
The RT140 removes this limitation, which can be helpful for jobs that need constant speed changes. You are not limited by a certain number of forward or reverse gears.
This makes the tractor flexible for both field work and transport jobs. In situations where you would normally have to shift repeatedly, the RT140’s CVT saves time and effort.
Top Transport Speed
The AGCO RT140 can reach a top transport speed of approximately 25 mph (about 40 km/h), depending on tires and final configuration. This speed allows you to move the tractor quickly between fields or down the road.
A higher road speed reduces travel time, especially if fields are spread out. You still benefit from stable handling at maximum speed.
With the ability to precisely control acceleration and deceleration, the tractor provides a smooth ride, even with heavy implements attached. The top speed is carefully matched to meet both safety standards and customer expectations for efficiency.
Drive (2WD / 4WD / AWD)
The AGCO RT140 is equipped with a standard 4WD (four-wheel drive) system. This feature provides better traction and control especially in soft, wet, or rough field conditions.
You can operate efficiently on uneven or slippery ground without losing pulling power. Four-wheel drive also improves steering control when working with heavy front or rear implements.
This can help minimize tire slippage, reducing wear on the tires. Switching between two- and four-wheel drive is not needed due to the permanent 4WD setup.
Differential-Lock & Final Drives
The AGCO RT140 comes with a differential lock. This feature ensures that both wheels on an axle rotate together when extra traction is needed, which helps you get unstuck or power through tough soil.
Final drives transfer the torque from the transmission to the wheels. On the RT140, these are heavy-duty and designed to handle both high torque and long hours.
They help maintain consistent performance under load. You engage the differential lock using a foot pedal or lever, making it easy to use when you notice wheel slip.
The rugged final drive components add strength and durability to the drivetrain, making it reliable for tough fieldwork.

Steering & Brakes
The AGCO RT140 tractor uses advanced systems for steering and braking. These systems help you control the tractor safely, even when working in tough field conditions.
Steering System (Hydrostatic / Power-Assisted / Mechanical)
You get power steering as a standard feature on the AGCO RT140. The system is hydrostatic, which means it uses hydraulic pressure to assist you in turning the steering wheel.
This makes your turns smooth and reduces strain during long workdays. This steering system helps provide precise control, so you can make sharp turns even with heavy loads.
Power steering gives you better response and less effort, important when working with large farm implements. The design also helps you steer if the tractor is moving at low speeds or when handling attachments.
For more stability, the AGCO RT140 uses a reliable front axle design. The components work together for both fieldwork and road driving.
With fewer mechanical linkages than older models, there is less wear and maintenance over time. These features ensure you experience steady, predictable handling in many situations.
Turning Radius (With Brakes)
The turning radius of the AGCO RT140 is compact for a 170 hp tractor. When you use the brakes, the turning radius gets even smaller.
This helps you maneuver easily at the end of rows or when working in tight spots. With brake-assisted turning, you can brake one rear wheel at a time.
This lets you pivot the tractor closer to its center and reduces the space you need to turn. On varied terrain or when making sharp field turns, this feature is helpful.
It improves your tractor’s ability to adjust its path quickly. This is essential for row crop farming, loader work, or making tight movements in barns and sheds.
Service Brakes (Wet Disc, Dry Drum, etc.)
The AGCO RT140 uses hydraulic wet disc brakes as its main service brakes. Wet disc brakes are fully enclosed within the axle, so dirt and water are kept out.
This design provides more consistent braking and longer service life compared to dry brakes. Hydraulic pressure applies equal force to all brake discs, giving you smooth, dependable stops even during heavy use.
Wet disc brakes are especially useful if you work on slopes or pull heavy loads, as they maintain their performance over long hours. Wet disc brakes also lower the risk of fade, which can happen with other brake types after repeated use.
Your stopping power stays strong, even if you’re hauling large trailers or implements. Maintenance is easier since the brakes are sealed and self-lubricating, requiring fewer adjustments and replacement parts.
Parking Brake Type
The parking brake on the AGCO RT140 is a manual, mechanically-activated system. It uses a lever inside the cab that engages the brake mechanism directly on the driveline or the rear axle.
This locks the wheels firmly in place when you’re parked on hills or flat ground. Mechanically-activated parking brakes are reliable because they don’t depend on hydraulic or electrical systems.
If power drops or there is a hydraulic issue, your tractor stays secure where you park it. You can apply or release the brake with a simple hand movement from the operator’s seat.
The mechanism is built for durability, so it holds the tractor even with heavy implements attached or when parked on inclines. You have clear feedback from the lever and can be confident your machine will stay put whenever it’s not in use.

Hydraulics
The AGCO RT140 tractor features a hydraulic system designed for heavy farm work. You get solid performance for both implements and steering, with strong flow rates and pressure to handle modern attachments.
System Type (Open-Center / Closed-Center / PFC)
The AGCO RT140 uses a closed-center hydraulic system. This kind of system keeps the hydraulic fluid pressurized and ready for immediate use.
Unlike open-center systems, the pump only works when you demand power, which improves efficiency. Closed-center hydraulics are common in high-horsepower tractors because they respond faster and can run several functions at once.
This design helps you when operating multiple implements. You get steady power, even if one function is temporarily demanding more flow or pressure.
The closed-center setup on the RT140 supports Precision Flow Control (PFC), so you can adjust flow rates as needed for different tasks. With PFC, you will not feel lag when switching between controls or activating attachments.
The system responds smoothly, letting you make precise adjustments in the field. Maintenance on closed-center systems is often easier, as the design limits unnecessary pump movement and extends component life.
Implement Pump Flow (L min⁻¹)
The implement pump handles all attachments that need hydraulic power, such as loaders or mowers. In the AGCO RT140, you will find a strong pump delivering about 110 liters per minute (L/min).
This high pump flow is key if you plan to run multiple implements or larger attachments. With this flow, you can expect fast reaction times and powerful hydraulic movement.
Rural work often demands quick response, and the RT140’s implement pump is sized to keep up. For example, when lifting heavy loads or operating complex machinery, steady and quick flow is crucial.
Using high-flow equipment is not an issue, as the RT140 can support most of today’s modern, high-demand implements. This high flow also helps keep operating temperatures under control, as the system moves fluid efficiently and reduces heat buildup.
Steering Pump Flow (If Separate)
On the AGCO RT140, steering and implement hydraulic systems may be integrated or separate, depending on final specifications. In many cases with closed-center PFC systems, steering has its own dedicated flow channel or pump.
If separate, the steering pump will often provide an additional 40–50 L/min flow just for steering and related controls. This means you do not lose steering power even if all hydraulic remotes are in use.
You can count on smooth, easy steering, even while running demanding implements. This is especially useful for row crop work or headland turns requiring fast, precise changes in direction.
If the steering shares a pump with implements, Precision Flow Control ensures that steering gets priority over other hydraulic functions, so safety and handling are never compromised.
Total Combined Flow
The total combined hydraulic flow tells you how much fluid the RT140 system can move all at once. For the AGCO RT140, total flow often ranges from 120 to 160 L/min, depending on the steering and implement pump configuration.
This total is important if you operate several hydraulic attachments at the same time. With this much flow, you can run large seeders, planters, or loaders without drop-off in power.
Efficient hydraulic flow means less waiting for cylinders to fill or attachments to react. The system can power up to six remotes, depending on configuration, so you have room to use several hydraulic-powered attachments without sacrificing performance.
System Pressure (bar / psi)
The RT140’s closed-center hydraulic system operates at a maximum pressure of about 200–210 bar (2,900–3,050 psi). High system pressure is needed for lifting heavy implements, fast loader movement, and working with demanding hydraulic tools.
This high pressure ensures precise control and strength. You get consistent lifting and digging force, which is especially useful for front loaders, backhoes, or other jobs that need reliable pressure.
Pressure relief valves in the system prevent over-pressurization, so you can operate safely. The system pressure level on the RT140 is standard for tractors in this horsepower class.
Remote Valves (Number & Type)
Remote valves, also called selective control valves (SCVs), allow you to connect and control external attachments. The AGCO RT140 can be equipped with up to 4–6 remotes.
You can choose between mechanical and electro-hydraulic (electric) remote valves. Mechanical remotes are simple and easy to maintain, using direct mechanical linkages.
Electro-hydraulic remotes offer push-button or joystick control. They provide more precise flow and timer functions, ideal for modern planters or sprayers.
Each remote is color-coded and can be locked in place for continuous operation. With up to six remotes, you can handle multiple machines at once, from balers to seeders to hydraulic top links.

| System Pressure | 200–210 bar (2,900–3,050 psi) | Lifts heavy loads, powers demanding tools, ensures safety |
| Remote Valves | 4–6 (mechanical/electro-hydraulic) | Connect, control, and run multiple attachments simultaneously |
Three-Point Hitch (3PH)
The AGCO RT140 comes equipped with a heavy-duty three-point hitch system that supports many agricultural implements. With high lift capacity and robust engineering, you can expect reliable performance for a range of field tasks.
Hitch Category (1 / 1N / 2 / 3)
This tractor’s three-point hitch is designed to fit Category II and IIIN implements. Category II hitches are common for large utility and mid-range row-crop tractors.
The IIIN (narrow) type allows you to use certain large implements that may require a narrower spacing. Using a Category II or IIIN hitch means you have access to a wide variety of equipment like plows, cultivators, sprayers, and more.
The hitch arms and pins are built for strength, so you can confidently attach heavier implements. Changing from one category to another only requires adjusting the hitch arms or changing the ball ends.
Make sure each implement matches the correct category to prevent issues with fit or safety during operation.
Lift Capacity @ Ball Ends
The AGCO RT140 three-point hitch has a substantial lift capacity, making it suitable for heavy-duty implements and attachments. Its lift capacity at 24 inches behind the ball ends is reported around 14,283 to 15,240 lbs (6,479 to 6,913 kg).
This high lift rating ensures you can handle large planters, heavier seed drills, disc harrows, or mounted sprayers without overloading your tractor’s hydraulic system. The strong lift also means you can quickly and safely raise and lower equipment while in the field.
Be sure to always check your implement’s weight and signal requirements, as trying to lift more than rated capacity can damage both the tractor and the implements.
Table: Three-Point Hitch Lift Capacity
| Lift Location | Capacity |
|---|---|
| 24″ behind ball ends | 14,283 – 15,240 lb |
| Maximum possible (est.) | Up to 15,240 lb |
Draft / Position Control
The RT140 is equipped with both draft control and position control systems. Draft control allows you to manage how deeply soil-engaging implements penetrate the soil by sensing the resistance on the hitch.
This makes plowing and tillage more consistent and helps avoid overloading the tractor. Position control lets you set and maintain a fixed height for your implements.
By adjusting the lever in the cab, you can raise or lower your implement to a precise level. This is useful for keeping seeders, sprayers, and other tools at the correct position for their work.
Both controls can usually be used together to get balanced performance, especially when working on uneven ground.
Top-Link Sensing (Yes/No)
The AGCO RT140’s three-point hitch includes top-link sensing as part of its advanced hydraulic control system. Top-link sensing means the tractor measures forces applied through the upper link of the hitch, rather than just through the lower arms.
This helps the tractor make faster and more accurate adjustments to implement depth, especially during heavy draft work like plowing. The system reacts when the implement hits tougher or softer ground, keeping your implement depth consistent and reducing soil compaction.
Top-link sensing improves traction control and enhances safety for you and your equipment. Make sure the top-link is properly set up and connected for the system to work effectively.

| Final-Drive Type | Planetary reduction gears | For robust power transfer and durability |
Maximum Front-Axle Load (kg)
The front axle of the AGCO RT140 is designed to manage substantial loads, especially when working with heavy front-mounted equipment or loaders. With an estimated limit near 5,000 kg, you can handle large implements, but it is vital to respect the actual rating listed in the operator’s manual for your specific tractor.
Loading above the recommended maximum leads to increased wear on axle bearings and steering components. Use proper ballast distribution, especially when you attach heavy implements to the three-point hitch, to maintain safe steering control and braking.
Frequent checks for tire air pressure, bearing temperature, and visible wear should be part of your maintenance routine. This helps avoid overloading and ensures that the front axle maintains its performance over time.
Maximum Rear-Axle Load (kg)
The rear axle is built to support the bulk of the tractor’s weight, including rear implements and any load transferred from towed equipment. On the AGCO RT140, the estimated maximum rear-axle load is about 9,000 kg.
This figure depends on your tire setup, use of duals, and ballast configuration. You should never exceed this load, as doing so can stress not just the axle but also the entire driveline and frame.
Overweight conditions might also lead to poor traction, reduced stability, and potential failure of rear components. Monitor your implement weights and payloads carefully using weight charts and manufacturer recommendations.
If you often operate near the maximum load, increase your inspection frequency and keep a record of wear or signs of fatigue on the axle and housing.
Final-Drive Type
The AGCO RT140 uses planetary reduction gears in the final drive. This system multiplies the axle torque while allowing for strong, steady power delivery to the wheels.
It is known for its durability and efficiency under high-load situations. Planetary reduction gears are enclosed and protected from dirt and moisture, which reduces maintenance needs.
The design spreads forces evenly, decreasing stress on single gears and increasing lifespan. For you, this means consistent performance even when hauling or working in challenging field conditions.
The combination of a reliable final-drive and robust axles lets the tractor handle high-horsepower applications without risking premature breakdowns.

The AGCO RT140 can be equipped with different front tire sizes based on the job. For standard agriculture tasks, common sizes include 14.9R28 or 380/85R28.
These provide strong traction and are built for durability while working with heavy implements. If you plan to work on grass or turf, larger and softer tires such as 21.5L-16.1 are available.
Turf tires spread the weight out and minimize ground damage, which is important for landscaping or light-duty field work. Industrial front tires (12.5/80-18) are made for strength and puncture resistance.
These are useful in projects that require frequent movement on gravel, roads, or construction sites. Always match your front tires to your primary field conditions for best results.
Standard Rear Tire Size
For the rear, standard AG tires like 18.4R38 or 460/85R38 are typical on the RT140. These large, deep-lug tires offer the grip needed to pull heavy loads and support mounted implements.
The tire size helps spread the weight for better stability and less soil compaction. Rear turf tires are available but less common, mainly for special applications where ground preservation is key.
If you need more load support, reinforced versions exist with increased ply ratings. Selecting the right rear tires ensures the tractor operates smoothly.
Pay attention to rim width and tire inflation, as both affect performance and longevity.
Optional Duals / Tracks / Flotation Kits
You can fit the RT140 with dual rear wheels to increase traction and stability, particularly in wet or loose soils. Duals are often identical to the standard rear tire size (18.4R38), simply mounted in pairs.
Rubber track kits are sometimes supported. Tracks reduce soil compaction even more than flotation tires by increasing surface contact.
They’re ideal for muddy or soft ground, as they greatly minimize rutting and help the tractor avoid getting stuck. Flotation kits use wider tires on both the front and rear axles.
These kits spread out the tractor’s weight across a bigger footprint. This is an advantage when working in soft fields or on freshly planted ground, as it helps prevent soil damage and keeps yields high.
Proper adjustment of these setups is critical for optimal tractor control.

For 4WD models, the wheelbase is slightly shorter at 117.9 inches (299 cm). This can help with tighter turns and added traction when working in the field.
A longer wheelbase increases ride comfort, but a shorter one can often improve maneuverability. When planning field layout or transport routes, these measurements help you know what to expect from your tractor’s footprint.
Overall Length
The overall length of the AGCO RT140 is about 210 inches. This can vary slightly based on tires and attachments.
Knowing the tractor’s length makes it easier to plan barn storage. It also impacts how easily you can maneuver in tighter working areas or around farm equipment.
A tractor of this length tends to have a larger turning radius. If you opt for front weights or additional implements, the total length may increase by several inches.
Overall Width (Minimum Tread)
Width affects stability and the ability to move through narrow rows or gate openings. The minimum tread width for the AGCO RT140 typically ranges from 92 to 96 inches, depending on wheel adjustments.
Your tractor’s minimum width is set by the narrowest rear wheel spacing. Wider settings offer more stability, which is useful when working on slopes.
Check your property’s narrowest passages before setting your tread width. Some models allow additional width adjustments for special applications.
Height to ROPS / Cab
Cab and Roll-Over Protective Structure (ROPS) height dictates how much vertical space you need for storage or when working under trees and other low objects. The AGCO RT140 stands about 120 to 124 inches tall at the cab top, depending on tires and roof option.
This height keeps you visible in the field and provides headroom in the operator cab. If you work in barns with low doors or store equipment inside, measure your entrances carefully.
If extra roof attachments or beacons are installed, add a few more inches to this measurement. Some models come with foldable ROPS, helping reduce height for transport or storage.
Ground Clearance
Ground clearance is important for working over rough terrain or row crops. The AGCO RT140 typically provides about 22 inches of clearance, giving room for moderate debris, stubble, or uneven ground.
With this amount of clearance, you are less likely to get stuck on field objects. For most traditional field work, this should be sufficient.
If you regularly drive across ditches or larger obstacles, a higher clearance might be needed. Tire selection and inflation can also slightly affect actual ground clearance.
Shipping Weight
The shipping weight of the AGCO RT140 ranges from 14,300 to 15,100 pounds. This is the weight of the tractor without fluids, ballast, and additional equipment.
You must know this weight for transport planning, especially when using trailers or dealing with weight limits on bridges. Heavier weights can affect fuel consumption during shipping as well.
When ordering a tractor, shipping weight influences delivery charges and may require special handling equipment. Always refer to your tractor’s serial plate or manual for the exact shipping weight of your chosen configuration.

Using only ultra-low sulfur diesel fuel is suggested to keep the fuel system clean and meet emissions standards. The engine uses electronic common rail injection, so it needs clean, quality diesel to protect sensitive parts.
Always check for water or dirt buildup in the fuel system. Replacing the fuel filter as recommended by the manufacturer also helps avoid costly engine problems.
DEF-Tank Capacity (If Applicable)
The AGCO RT140 does not use a DEF (Diesel Exhaust Fluid) system. This model meets its emissions requirements using other engine technologies, so you don’t have to manage or refill a DEF tank.
Since there is no DEF on this tractor, this means there is less maintenance. You will not need to source DEF or clean DEF lines.
If you use other later AGCO models with DEF, always check the DEF level and use only high-purity fluid. But for the RT140, you do not have to worry about it.
Engine Oil Capacity
Your AGCO RT140 needs regular engine oil changes to keep running in peak condition. The engine oil system holds about 5.3 gallons (20 liters) of high-quality diesel engine oil.
Check your engine oil with the dipstick before each major use. When changing the oil, always use the grade and type recommended in your operator’s manual.
Most users select oil that meets or exceeds API CJ-4 specs or newer. Cold weather, hard use, or dusty conditions may require you to change the oil more often.
Be sure to replace the oil filter at every oil change. This protects your engine from damage and keeps oil flowing smoothly to key parts.
Hydraulic/Transmission Oil Capacity
The hydraulic and transmission system in your RT140 is a closed, shared-loop system. The total oil capacity for the hydraulics and transmission is about 37 gallons (140 liters).
You must use AGCO-approved hydraulic/transmission fluid. This fluid powers the loader, three-point hitch, and powershift transmission.
Check fluid levels on the dipstick or sight glass every week, especially before heavy work. Change the hydraulic/transmission oil on the schedule in your manual.
Dirty or low oil can cause slow hydraulic response, noisy pumps, or even expensive repairs. Regular filter changes and inspections help you catch problems before they get worse.

Proper function is crucial for preventing battery drain during extended use or in cold temperatures.
Charging Output (Amps)
The charging output usually falls between 120 to 150 amps depending on the tractor’s configuration and optional equipment. This output is necessary to support high electrical loads, especially when using features like air conditioning, heated mirrors, and extra lighting.
With higher amp output, your tractor can maintain battery charge efficiently even when using many electrical accessories. If you install aftermarket electronics such as GPS, extra work lights, or a two-way radio, this output keeps voltage levels steady and reduces the risk of undercharging.
If your alternator output falls below specifications, you may notice dim lights or slow battery recharge. Regular checks are recommended to keep the system in top shape.
Battery Voltage
The AGCO RT140 uses a standard 12-volt battery system. This is the industry norm for most farm tractors today.
A 12-volt platform allows consistent performance for all starting, lighting, and accessory circuits. When you check the battery, measure voltage with the engine off.
A healthy battery should read around 12.6 volts at rest. Charging or starting will show slightly higher numbers.
If you see numbers below 12 volts, the battery may not hold enough charge for reliable starting. Most 12-volt systems are compatible with a wide range of aftermarket batteries, but it’s best to use one that meets or exceeds factory ratings.
Battery CCA Rating
Cold cranking amps (CCA) measure a battery’s ability to start the engine in low temperatures. The battery for the AGCO RT140 is usually rated between 950 and 1200 CCA.
This range ensures the tractor will start in harsh weather, even during freezing conditions. High CCA is important on large diesel engines like the RT140’s because it takes more power to turn the engine at cold temperatures.
Always check the CCA rating before replacement. Using a battery with insufficient CCA can cause hard starts or prevent the tractor from starting at all.
Battery connections should be kept clean and tight, especially before the winter season when CCA performance is most critical.
