Engine Make & Model
You will find that the AGCO RT140A uses a 6.6-liter engine manufactured by AGCO. This engine is based on a 6-cylinder in-line configuration, which is typical for large tractors in this class.
It uses 24 valves in total—4 valves per cylinder—for improved airflow and higher efficiency. The engine model often referenced is the AGCO Power 6.6L, sometimes branded or sourced from AGCO Sisu Power (previously Sisu Diesel).
The engine setup uses overhead camshaft technology, which supports improved timing and better fuel mixing. AGCO engines are known for their durability, especially in agricultural applications.
Fuel Type & Emissions Tier
This tractor runs on standard diesel fuel. Diesel engines are preferred for their higher torque and fuel economy, especially under heavy load.
The AGCO RT140A meets Tier 3 emissions standards. This was required for tractors manufactured after 2006, ensuring reduced levels of nitrogen oxides and particulates.
Tier 3 compliance was achieved by optimizing fuel injection timing and incorporating improved turbochargers and aftercoolers. For users operating in areas with emissions regulations, you can expect this model to be compliant and accepted for use.
Cylinders / Displacement
The engine features 6 cylinders in an in-line arrangement. This design provides a balance between smooth operation and power output.
Displacement for the RT140A engine is 402.5 cubic inches (ci) or 6.6 liters (L). Displacement refers to the total volume swept by all pistons inside the cylinders, and it directly affects how much air and fuel can be drawn in for combustion.
A larger displacement allows for more power and torque, which you will notice during heavy tillage or hauling work. Having 24 valves also improves air and fuel flow through the cylinders, supporting efficient combustion.
Rated Horsepower (Gross & Net)
You get a gross engine power of 170 horsepower (hp) or 126.8 kilowatts (kW). Gross power indicates the engine’s total output before losses from the transmission and auxiliary systems are considered.
The PTO (Power Take-Off) horsepower is rated at 140 hp (104.4 kW). PTO power is what’s available to drive implements like balers or mowers and is always lower than gross engine output because of mechanical losses.
In field tests, the drawbar power has been measured at about 127.7 hp (95.2 kW). These figures ensure you have sufficient power for a wide range of agricultural tasks, from tilling to transport.
Peak Torque (Nm @ Rpm)
The AGCO RT140A’s engine provides high torque for demanding work. While exact peak torque figures in Newton meters (Nm) are not always provided, engines of this size and rating typically produce between 680 and 750 Nm of torque.
Peak torque is generally available at around 1,400 to 1,600 rpm. This helps you maintain consistent pulling power under varying loads.
The broad torque curve enables you to keep working efficiently even when soil or crop conditions change. Higher torque at lower rpm also means fuel efficiency and less engine wear during continuous, heavy-duty use.
Compression Ratio
The engine in the RT140A uses a compression ratio of approximately 16.5:1. Compression ratio is the ratio of the cylinder volume when the piston is at the bottom of its stroke to the volume when the piston is at the top.

With 32 speeds, you can match engine output to a wide variety of tasks, from tillage to haymaking. The multiple ranges make it easy to fine-tune speed, whether you need slow, controlled movement or faster operation for lighter work.
The combination offers you more choices for optimal fuel efficiency. For controls, you use a lever or pushbuttons in the cab, so gear shifting is quick.
Whether you are maneuvering at low speeds or need to accelerate for transport, the high number of gears gives you the flexibility.
Top Transport Speed
The RT140A is capable of achieving a top transport speed that is typical for field tractors of its class. The actual transport speed will usually be around 25 mph (40 km/h), depending on your regional regulations and tire setup.
This maximum speed allows you to move between fields or along roads efficiently. It reduces time lost in transit and helps you manage large areas more productively.
If you’re frequently working over distances, this speed is sufficient for keeping up with most farm logistics. It is important to note that speed is electronically limited to meet local safety standards.
When towing implements or loaded trailers, maintaining stability at top speed is critical. The tractor’s transmission manages the power delivery to help ensure smooth acceleration without sudden jerks.
Drive (2WD / 4WD / AWD)
The AGCO RT140A is primarily available as a 4WD (four-wheel drive) tractor, improving traction and stability in a range of soil conditions. This makes it suitable for fieldwork in both wet and dry environments.
With 4WD engaged, you get more power to the ground, reducing slippage and increasing pulling capability. This is especially useful for heavy tillage or when the ground is less than ideal.
Some rare configurations could be 2WD, but these are uncommon. Most units in North America are equipped for four-wheel drive, catering to large-scale farm operations.
4WD ensures better weight distribution. You’ll also notice improved steering control and safety on inclines compared to 2WD.
Differential-Lock & Final Drives
Your RT140A includes a differential-lock feature to prevent wheel slip when working in tough or uneven conditions. This can be engaged when you need extra traction, such as pulling through mud or working on slopes.
The differential-lock works by forcing both wheels on an axle to rotate at the same speed, maximizing grip. This function is activated by a switch or lever in the cab and can be disengaged easily.
The final drives are designed for durability and transferring high levels of torque from the transmission to the wheels. The tractor uses inboard planetary final drives for strength and reliability, suited for heavy-duty applications.
Regular use of differential-lock is helpful when traction is critical. The system helps prevent spinning and uneven wear on tires, and the robust final drives contribute to long service life.

Steering & Brakes
The AGCO RT140A tractor features advanced steering and braking systems to improve control, comfort, and safety during field operations. These features are designed for demanding tasks and heavy workloads.
Steering System (Hydrostatic / Power-Assisted / Mechanical)
You get power steering as standard on the AGCO RT140A. This power-assisted steering system uses hydraulics to make turning the wheel easy, even when the tractor is loaded or moving at low speed.
The steering is precise and helps you maintain accurate rows, especially in tight field conditions. It reduces arm fatigue during long work hours.
The power steering system also includes a backup hydraulic pump for continued operation if the main system fails, increasing reliability. No manual-mechanical steering is used—power steering is standard.
You don’t need to fight the wheel or struggle to steer, even with front loaders or heavy implements attached.
Turning Radius (With Brakes)
A tight turning radius is important for working in small spaces and making accurate passes in the field. The AGCO RT140A offers a compact turning radius, which is improved when you apply the brakes.
When you use the individual (split) brakes, the inside rear wheel slows down, allowing the tractor to pivot more sharply. This makes headland turns and maneuvering at field edges much easier.
The turning radius is further helped by the power steering system, so you can steer quickly and safely. For row-crop work, orchard use, or narrow plots, this feature saves time and helps you avoid unnecessary double-passes or missed spots.
Service Brakes (Wet Disc, Dry Drum, etc.)
The AGCO RT140A uses hydraulic wet disc brakes. Wet disc brakes operate inside a sealed, oil-filled housing, which keeps the discs cool and clean.
This type of brake provides consistent stopping power and requires much less maintenance than dry drum or dry disc brakes. Wet disc brakes last longer because the oil prevents heat buildup and reduces wear.
They are also less likely to fade under repeated or prolonged braking, which is useful in hilly terrain or when towing heavy trailers. The hydraulic system provides even pressure to all wheels, so you get smooth, balanced braking.
These brakes are designed for reliability and safe operation under all farming conditions.
Parking Brake Type
The parking brake on the AGCO RT140A is a mechanical hand-operated brake, often working through the same wet disc system as the service brakes. You engage it using a lever inside the cab.
Once set, the parking brake locks the brakes firmly, preventing unintentional movement, even on slopes or uneven ground. This simple mechanical design ensures the brake stays engaged even if hydraulic pressure is lost.
You don’t have to worry about the tractor rolling away during loading, unloading, or maintenance. The hand lever is easy to reach from the operator’s seat for added convenience.
| Feature | Description | Benefit |
|---|---|---|
| Steering System | Power-assisted (hydrostatic); hydraulic backup pump | Easy, precise control; less operator fatigue |
| Turning Radius (with Brakes) | Tight turns using split brakes; quick maneuvering | Better for corners and narrow fields |

Hydraulics
The AGCO RT140A hydraulic system supports demanding implements and provides reliable, smooth performance in the field. You benefit from a solid mix of power, flow, and adaptability.
System Type (Open-Center / Closed-Center / PFC)
The AGCO RT140A is fitted with a closed-center, pressure and flow compensated (PFC) hydraulic system. This setup means hydraulic oil only flows when needed, which cuts down on wasted energy.
A PFC system helps save fuel and reduces heat buildup. When you operate multiple implements or functions at the same time, you can expect steady oil flow and pressure.
The closed-center design gives you quicker response and better control compared to older open-center systems. With the PFC system, you’re ready for modern implements that need strong and precise hydraulic power.
Maintenance is usually easier, and the system is quieter during operation.
Implement Pump Flow (L Min⁻¹)
The main implement pump on the RT140A supplies a high-flow rate, supporting efficient equipment operation. The pump can deliver about 110 liters per minute (L/min), which matches the requirements of most large implements.
You get consistent performance when lifting, lowering, or adjusting heavy equipment like planters, drills, or plows. This robust flow rate also helps avoid delays, letting you finish tasks more quickly.
High flow means you’re able to use hydraulic motors and functions that need strong, continuous oil flow. Even when using multiple hydraulic outlets, flow remains steady thanks to the well-designed pump.
Steering Pump Flow (If Separate)
The steering circuit on the RT140A is separate from the main hydraulic pump. This setup ensures that steering won’t be affected either by implement use or by heavy hydraulic demand.
The steering pump has a dedicated flow, typically around 45–50 L/min. This keeps your steering stable and responsive at all times, even if you’re operating several hydraulic remotes.
Separation of steering and implement pumps increases safety. It also reduces driver fatigue, as you do not have to fight steering lag under load.
Total Combined Flow
When combining pump outputs, the AGCO RT140A can reach a total hydraulic flow (implement plus steering systems) of up to 160 L/min. For simultaneous use of steering and implements, this combined output is crucial.
You have enough power and oil flow for running demanding tools, even when turning or cycling equipment simultaneously. Large planters, air seeders, and loaders all benefit from this combined high-flow system.
It reduces downtime and allows for precise, responsive operation of hydraulically controlled features.
System Pressure (Bar / Psi)
Peak system pressure for the RT140A’s closed-center hydraulic setup is about 200–210 bar (around 2,900–3,050 psi). This high pressure supports the use of heavy-duty cylinders and high-force implements.
You can raise, lower, and control large equipment smoothly without pressure drops. High pressure also helps run functions that depend on strength, such as lifting or down-force adjustments.
The hydraulic lines and components are engineered to handle this pressure safely. Proper pressure settings help your equipment last longer and perform more reliably.
Remote Valves (Number & Type)
The tractor is equipped with up to four rear remote valves as standard. These are electrohydraulic, which means you can control them with switches or levers from the cab.
Each valve supports single- or double-acting operation. You can hook up multiple implements at once, including those that need live hydraulic flow.
Flow for each valve is adjustable, letting you match performance to each tool. Having four valves gives you flexibility for using planters, mowers, or trailers.
The electrohydraulic type lets you control multiple functions precisely and intuitively.

Three-Point Hitch (3PH)
The AGCO RT140A is equipped with a robust three-point hitch that supports a wide range of implements. This system is designed for reliable performance, high lift capacity, and precise control.
Hitch Category (1 / 1N / 2 / 3)
You will find the AGCO RT140A comes with a Category 3 three-point hitch. This size is meant for heavy-duty agricultural use and can handle larger implements such as plows, cultivators, and planters.
Category 3 hitches feature lift arms and pins with a 1.25-inch diameter. The spacing between the lift arms is also standard for Cat 3, about 38 inches.
Using this hitch, you can attach most large implements found on commercial farms without modification. The hitch type and dimensions are important because they make sure your implements fit securely and work safely on your tractor.
If you use smaller or lighter implements, adapters for different categories are available, but the Category 3 system is built for serious field work.
Lift Capacity @ Ball Ends
The rated lift capacity at the ball ends for the AGCO RT140A’s 3PH is designed to meet demanding tasks. It often exceeds 8,000 pounds, giving you the ability to handle large, heavy attachments like large disks, chisel plows, and drills.
A higher lift capacity means you can work with implements that have heavier frames or larger working widths. This helps you cover more acres per pass and get more done in less time.
The lift arms are robust to provide stability and safe lifting even with challenging terrain.
| Feature | Value |
|---|---|
| Hitch Category | Category 3 |
| Lift Capacity @ Balls | 8,000+ lbs (approximate) |
| Draft/Position Control | Both available |
| Top-Link Sensing | Yes |
Draft / Position Control
Your RT140A includes both draft and position control as part of its hitch system. Draft control automatically adjusts the depth of soil-engaging implements, such as plows, to maintain a constant load by sensing resistance from the soil and raising or lowering the implement as needed.
Position control lets you set and hold the precise height of your implement, no matter the working conditions. You simply adjust the lever in the cab, and the system raises or lowers the hitch to your chosen position.
Both controls increase your efficiency and make sure you achieve uniform results in the field. They also help reduce operator fatigue because you make fewer manual adjustments from the cab.
Top-Link Sensing (Yes/No)
The AGCO RT140A is equipped with top-link sensing. This feature works with draft control to enhance how the tractor controls the depth of tillage tools.
Top-link sensing uses a sensor on the top link of the hitch to measure the force the implement applies back toward the tractor. When resistance changes—like when hitting hard soil—the sensor tells the hitch to raise or lower the implement to keep the load steady.
You benefit from top-link sensing because it helps even out your work, produces smoother seedbeds, reduces wheel slippage, and helps protect both the tractor and the implement from overload. This technology is important when using large cultivators or plows.
