Engine Specifications
The AGCO RT135 uses a strong 6-cylinder Cummins diesel motor. You get reliable horsepower, responsive torque, and a design made for modern farming.
Engine Make & Model
Your AGCO RT135 is powered by a Cummins turbocharged diesel engine. Cummins is a respected name in heavy equipment, known for building engines that last and provide consistent performance.
The specific model in this tractor is a Cummins 6.7L, 6-cylinder inline, which uses advanced turbocharging for more power and efficiency. This engine is widely used in agricultural equipment because it is built for high-demand work and features a good balance between output and fuel efficiency.
Having a Cummins engine means easier access to parts and service, along with an established track record of durability. The design makes it suited for repeated heavy use over many seasons.
Fuel Type & Emissions Tier
You will use diesel fuel to run the AGCO RT135. The tractor’s engine is designed for high-torque needs often found in modern farm work.
Depending on your region and the production year, this model meets certain emissions standards required for agricultural machines. Most RT135 tractors are classified within EPA’s Tier 2 or equivalent stage, depending on where and when it was sold.
Diesel offers better energy density than gasoline, which means more power output per gallon. The Cummins engine in the RT135 balances performance with emissions controls, using technology like direct injection and turbocharging to maintain strong output while reducing pollutants.
Cylinders / Displacement
There are 6 cylinders in the engine, arranged in a straight line (inline-6). This format helps provide smooth operation and balanced power delivery.
Inline-6 engines are popular in larger tractors because they minimize vibration and stress on moving components. The displacement of the engine is 6.7 liters (or 408 cubic inches).
Displacement tells you the total volume all the pistons move through during one cycle. Larger displacement means more air and fuel can be burned, giving you more torque and horsepower.
A 6.7L displacement in a farm tractor is designed for pulling heavy loads and operating large implements. This engine size is enough to handle most fieldwork without being overly heavy or inefficient.
Rated Horsepower (Gross & Net)
You get a rated gross horsepower typically advertised around 135 hp. Some sources note a maximum or estimated output of up to 144 hp, but the standard rating remains 135.
When measured at the drawbar or PTO (the places it matters during work), you see actual usable horsepower. PTO (tested): about 135 hp.
Drawbar (tested): about 108-110 hp, depending on test conditions. The net horsepower is usually a few points lower than gross because it accounts for the power needed to run engine accessories.
It’s important to use the PTO and drawbar numbers to know what the tractor can actually do on your implements and attachments.
Peak Torque (Nm @ rpm)
Maximum torque defines how much rotational force the tractor engine can deliver. The RT135’s Cummins engine produces about 720 Nm (531 lb-ft) at its rated peak, according to independent sources.
Peak torque usually happens at medium engine speeds, giving you the pulling force needed when starting under load or working tough soil. High torque at lower RPMs means you can drive heavy implements without the engine bogging down.
This engine’s torque curve is flat, which helps you maintain power across a wide working range. Tractors with this much torque are suited for heavy secondary tillage, pulling planters, and other intensive operations.
Compression Ratio
The RT135’s Cummins engine typically uses a compression ratio of around 17.3:1. Compression ratio means how much the fuel/air mixture is squeezed in the cylinder before ignition.
A higher ratio like this is common for diesels, allowing the engine to extract more energy per explosion and operate efficiently with diesel fuel. This improves fuel economy and boosts overall engine efficiency.
Because diesels ignite through pressure and heat, not spark, the higher compression ratio leads to more low-end power and reliability. Maintenance is key, since high-ratio engines need robust components to handle the stress.
Cooling System & Capacity
A liquid-cooled system ensures the engine temperature stays within safe limits, even at high loads. The RT135 uses a radiator and coolant mix, which circulates throughout the engine to absorb and remove heat.
The cooling system capacity is typically sized to handle prolonged fieldwork. The actual capacity in the RT135 is approximately 20-25 liters (about 5-6.5 gallons), which is sufficient for its displacement and power rating.
A well-designed cooling system helps prevent overheating, reduces wear, and supports longer service intervals. You will need to check coolant levels and system condition as part of regular tractor maintenance.

Power Take-Off (PTO)
The AGCO RT135 provides multiple PTO features important for operating various types of farm equipment. You can use it with implements that need different horsepower and speed settings.
The tractor is designed for flexibility and dependability during PTO use.
Claimed PTO Horsepower
The AGCO RT135 tractor has a claimed PTO horsepower of 135 hp (100.7 kW). This means the tractor can deliver up to 135 horsepower to your implements through the PTO shaft.
This rating is essential for running heavy-duty tools like balers, mowers, and grain augers. You can operate larger and more demanding equipment thanks to this level of power.
When working with high-resistance implements, you will have enough horsepower to handle fieldwork efficiently. The 135 PTO horsepower is a reliable measure used by equipment makers to match machines to your needs.
The PTO horsepower is tested separately from the engine horsepower, which is why the PTO power may appear lower. This is normal and is due to energy lost between the engine and the PTO system.
The rating supplies accurate expectations for actual work performance.
PTO Type (Independent / Live / Economy)
The AGCO RT135 uses an independent rear PTO system. This type allows you to control the PTO separately from the tractor’s movement.
You can engage or disengage the PTO at any time, even while the tractor is standing still or in motion. An independent PTO gives you flexibility for starting and stopping implements without affecting your travel speed.
This is helpful for processes like baling, mowing, or when you need to quickly stop a piece of equipment for safety reasons. You operate the PTO through a direct control lever or switch.
This feature improves safety and efficiency, especially in tough farm conditions. The RT135 does not have an economy or live PTO option as standard, so all PTO control is fully independent for direct and reliable operation.
PTO Speeds (540 / 1 000 rpm)
The AGCO RT135 offers two rear PTO speed options: 540 and 1,000 rpm. These are the most common PTO speeds, letting you work with a variety of attachments based on their requirements.
The dual-speed setup is practical for both light and heavy tasks. You can select the speed by a mechanical shift or lever, depending on your implement’s needs.
Some tools, like small mowers, often use the 540 rpm setting. Larger and more power-hungry equipment will use 1,000 rpm for optimal results.
Switching between speeds lets you match the PTO output to your tool’s rated input. This helps protect both the tractor and the equipment from damage.
It also improves energy efficiency during operation by using the right power setting for each job.

|---|---|---|
| Claimed PTO Horsepower | 135 hp (100.7 kW) | Maximum power delivered at the PTO shaft |
| PTO Type | Independent | Engage/disengage PTO regardless of tractor movement |
| PTO Speeds | 540 / 1,000 rpm | Two selectable speeds for different implements |
| PTO Control | Lever/Switch | Control method depending on model |
| PTO Shaft Location | Rear | Standard rear PTO shaft |
Transmission & Drivetrain
The AGCO RT135 gives you high power and flexibility through its advanced transmission and drivetrain. You get strong pulling ability, smooth operation, and control across different field and road conditions.
Transmission Type (Syncro, Powershift, CVT, HST)
The AGCO RT135 features two main transmission types depending on the configuration you choose: a 32-speed partial powershift and a continuously variable transmission (CVT). The powershift transmission allows you to shift between gears without clutching, which saves time and reduces fatigue, especially during heavy work or frequent speed changes.
The CVT, or continuously variable transmission, provides smooth, step-less speed adjustments. It lets you pick any speed within its range for maximum fuel efficiency and precision.
Many operators prefer the CVT for loader work or applications that require frequent changes in speed and direction. Each type is designed for durability and long service life, even with heavy daily use.
Number of Gears / Ranges
With the partial powershift transmission, you get 32 forward and 32 reverse gears. This wide range gives you fine control over your speed.
You can match the tractor’s pace with your job, whether you are tilling, planting, or transporting. Each range is easy to select without complex shifting steps.
The number of gears allows you to pick the best speed and torque for any field or road condition. The CVT takes another approach, letting you move seamlessly from low to high speed without a fixed set of gears.
Top Transport Speed
Your AGCO RT135 can reach a top transport speed of about 25 to 30 mph (40 to 48 km/h), depending on the transmission type and tire setup. This fast road speed is helpful for moving between fields or traveling on public roads.
The CVT version often makes it easier to reach and hold higher transport speeds, as it doesn’t require you to shift through gears or ranges manually. Safe handling at high speeds is supported by responsive brakes and stable steering.
Drive (2WD / 4WD / AWD)
The AGCO RT135 is available in both two-wheel drive (2WD) and mechanical front-wheel drive (4WD or MFWD) versions. Most models are ordered with MFWD for better traction, stability, and power transfer during field work.
With 4WD engaged, you get improved grip in muddy, uneven, or loose soil conditions. The tractor can shift between 2WD and 4WD as needed, so you can match the drive mode to your current task.
This flexibility helps reduce tire wear and fuel use when 4WD isn’t necessary.
Differential-Lock & Final Drives
The rear and front axles both have electro-hydraulic differential locks on the AGCO RT135. This means you can engage the diff-lock with a button, helping both wheels turn at the same speed to prevent slipping in tough spots.
Final drives are heavy-duty and designed to handle the tractor’s full power. By spreading the torque evenly, they help avoid wear and tear.
These features keep the AGCO RT135 steady under load and reduce downtime from getting stuck or damaging driveline parts.

|---|---|
| Transmission Type | 32-speed partial powershift or continuously variable transmission (CVT) |
| Number of Gears/Ranges | 32 forward, 32 reverse (powershift); infinite in range with CVT |
| Top Transport Speed | 25–30 mph (40–48 km/h) |
| Drive Options | 2WD or mechanical front-wheel drive (MFWD/4WD) |
| Differential Lock | Electro-hydraulic front and rear; engaged by button |
| Final Drives | Heavy-duty, designed for even power distribution and long service life |
Steering & Brakes
The AGCO RT135 offers modern steering and reliable braking features. Systems are designed for smooth handling and safe operation, whether maneuvering in tight spaces or handling heavy loads.
Steering System (Hydrostatic / Power-Assisted / Mechanical)
You get hydrostatic power steering with the AGCO RT135. This system uses hydraulic pressure to assist your steering, which means you need less effort to turn the wheel, especially at low speeds or while stationary.
Power steering makes it easier to handle attachments or heavy trailers. A hydrostatic system responds quickly, providing immediate feedback.
The wheel remains easy to turn during long workdays and reduces arm fatigue. Built for reliability, the components are protected in the cab area and less likely to fail in tough conditions.
The power steering design means you also gain improved safety, because you retain more control, even if one system fails. Mechanical steering is not used on this model, and manual effort is minimized compared to older tractors.
Turning Radius (With Brakes)
The tractor’s turning radius is enhanced by the ability to engage brakes on the inside wheel during sharp turns, also known as brake-assisted turning. This feature helps you work efficiently in smaller fields or barns, where space is limited.
With the brakes applied during a turn, the turning circle is reduced further. This is especially helpful when using a front-end loader or attaching implements.
Even at low speeds, this system delivers precise cornering without skidding, and heavy loads do not limit your ability to turn sharply. If you regularly need to navigate through gates, around obstacles, or in tight rows, this brake-assisted turning saves time and reduces soil disturbance.
Service Brakes (Wet Disc, Dry Drum, etc.)
The RT135 uses hydraulic wet disc brakes. This design keeps the braking components sealed in oil, which reduces wear and prevents overheating.
You benefit from reliable stopping power, even when working on slopes or transporting heavy loads. Wet disc brakes require less maintenance than dry drum brakes and work well in muddy or damp conditions.
The oil bath extends the life of the brakes and maintains their performance over years of use. Braking action is smooth and consistent, reducing the risk of skids or loss of control.
Hydraulic actuation means you get even pressure and a predictable response each time you press the pedal.
Parking Brake Type
The parking brake on the RT135 is also designed for safety and reliability. It uses a mechanically activated brake system that locks the transmission, preventing the tractor from rolling when left on a slope.
You can set or release the parking brake using a lever within easy reach in the cab. It holds the tractor securely, even when attached to heavy implements or parked on soft ground.
The design is sturdy and does not easily wear out. This feature ensures peace of mind when you need to leave the tractor unattended, whether you are working on a hill or loading and unloading hay.

|---|---|---|
| Steering System | Hydrostatic Power Steering | Less effort, easy maneuverability |
| Turning Radius | Brake-assisted, sharp turns | Better control in tight spaces |
| Service Brakes | Hydraulic Wet Disc | Strong stopping, low maintenance |
| Parking Brake Type | Mechanical, transmission lock | Safe on slopes, reliable holding |
Cab & Operator Station
You will find that the AGCO RT135’s operator station is designed to help you work longer with less fatigue. The cab comes with several features for comfort and safety, including a sealed environment, advanced climate control, and an ergonomic seat with modern suspension.
ROPS / Cab Option
The AGCO RT135 provides a fully enclosed cab as standard equipment. This cab gives you protection from weather, dust, and noise.
For safety, it has a built-in Roll Over Protective Structure (ROPS) to help guard you during rollovers and accidents. You can expect windows with good visibility and doors that seal well, keeping out unwanted air and debris.
The controls for cab entry are easy to reach, and you can open and close the cab without much effort. The cab is also designed to be spacious, so operators of varying heights and sizes can work comfortably.
The ROPS is approved and tested for agricultural use. This adds to your peace of mind, especially when working on uneven or sloped ground.
Some models may offer open station options in specific markets, but the enclosed cab with ROPS is most common.
Climate Control (A/C, Heater, Filter)
Inside the cab, you get an automatic climate control system as an option. This system keeps the air cool in the summer with air conditioning (A/C) and warm in the winter with a reliable heater.
You can set and maintain the temperature using simple controls, letting you focus on your work instead of worrying about comfort. Clean air is important.
The system includes air filters that reduce dust, pollen, and small particles inside the cab. Even if you are working in very dusty fields, the filters keep the air inside cleaner and healthier to breathe.
You can adjust the air vents to direct airflow where you need it. The fan speeds and temperature are also simple to control, so you can make fast changes as needed.
These features let you stay productive in any season or weather condition.
Seat & Suspension
The operator seat in the AGCO RT135 is designed with comfort in mind. It features a suspension system that helps absorb shocks and bumps from rough fields or uneven terrain.
This reduces back strain and tiredness, even after hours of use. You can adjust the seat height, tilt, and position.
Armrests, lumbar support, and seat rotation functions are included on most models. This makes it easier to find the best position for your body size and reach all controls easily.
Many seats come with a mechanical or air suspension system. This feature “floats” the seat above the floor, taking the worst hits from rough operating conditions.
Seat covers use tough, easy-to-clean material in case of spills or dirt from boots and clothing.
Noise Level (dB A @ Operator Ear)
The cab is sealed and insulated to lower outside noise. Sound levels at the operator’s ear are typically around 72–76 dB(A) during most operations.
This is quiet for tractors in this horsepower class. The quiet environment helps you focus and reduces tiredness from long days in the field.
Window seals, insulation material, and a thick cab floor all work together to cut down on engine and transmission noise. You are protected from noisy implements, making cab conversations and use of radios much easier.
Ear protection is not required for normal use. The design reduces both overall sound and annoying high-frequency noises.

Hydraulics
The AGCO RT135 tractor uses a hydraulic system built for tasks that need reliable power. You get dependable control with pressure, flow, and remote features that let you handle various attachments and jobs.
System Type (Open-Center / Closed-Center / PFC)
The RT135 tractor is equipped with a closed-center, load sensing hydraulic system. This type of system helps you use hydraulic power efficiently by providing oil only when it’s needed.
The closed-center design also allows for precise control, which is important when running equipment like loaders or hydraulic tools. With load sensing, you can run multiple hydraulic functions at the same time without a drop in performance.
The system adjusts the flow and pressure based on the demand from your implement, which keeps the tractor from wasting power. This kind of system is especially useful in jobs that need both the loader and rear remotes to work at the same time, so you keep control under any load.
Implement Pump Flow (L Min⁻¹)
The RT135 has a strong implement hydraulic pump that supplies plenty of oil flow for running your implements. The implement (main) pump flow is around 98 liters per minute (L/min), which gives you enough flow for demanding tools such as large planters, air seeders, or hydraulic motors.
High pump flow is important if you operate implements that need constant or high-volume flow, like a baler or loader. This level of performance also means that you can raise and lower heavy implements without delay or slow cycling.
Steering Pump Flow (If Separate)
On the AGCO RT135, the steering pump is not completely separate from the main hydraulic system. Instead, it uses a load-sensing system that prioritizes steering so you always have control when turning.
You get reliable steering response even while using hydraulic tools at the same time. The hydraulic system automatically directs the right amount of flow to the steering if needed, which is key for safety.
If you are doing loader work or working in tight areas, the system makes sure the steering remains light and accurate. You won’t notice any lag or stiffness in the steering wheel when using hydraulics for other implements.
Total Combined Flow
When you combine the main implement pump flow and the oil available for steering, you get a total hydraulic flow of about 100 liters per minute. This total combined flow means you can multitask with multiple hydraulic circuits, especially when using implements with several hydraulic needs.
The high combined flow rate gives you flexibility with tools like drills or air seeders that use both rear remotes and load-sensing lines. You do not have to worry about slow operation when multitasking, since the system delivers steady flow to every part that needs it.
System Pressure (bar / psi)
The hydraulic system of the RT135 runs at a maximum pressure of about 200 bar (2,900 psi). This high pressure lets your implements work with full force, giving better lifting and pushing performance.
With up to 200 bar available in the circuit, even tough hydraulic tasks are possible, such as lifting heavy 3-point implements or using large loader attachments. The pressure rating is set so you have the power for both small and large implements.
Safe but powerful, the system uses wet disc brakes that run on hydraulic power, so stopping is smooth and controlled even under tough conditions.
Remote Valves (Number & Type)
The AGCO RT135 features up to four rear remote hydraulic valves as standard or optional equipment. These valves are electro-hydraulic, meaning you operate them with switches or levers in the cab for simple control.
Remote valves let you run attachments like balers, rakes, or hydraulic lift trailers. You can have dual-function remotes for tools that need both raising/lowering and powering hydraulic motors.
The number and type of remotes can vary based on the RT135’s options, but most units have at least three, with the fourth available for high-demand users. Extra remotes add flexibility, so you can change tools without stopping or swapping hoses.
| Hydraulic Feature | Specification |
|---|---|
| System Type | Closed-center, load-sensing |
| Implement Pump Flow | ~98 L/min |
| Steering Pump Flow | Load sensing, prioritized from main |
| Total Combined Flow | ~100 L/min |
| System Pressure | 200 bar (2,900 psi) |
| Remote Valves | 3–4 electro-hydraulic (rear) |
Three-Point Hitch (3PH)
The AGCO RT135 comes with a heavy-duty three-point hitch system designed for large implements. You get precise control, a strong lift system, and flexible compatibility for many types of equipment.
Hitch Category (1 / 1N / 2 / 3)
You get a Category II/IIIN rear hitch on the AGCO RT135. This means you can attach implements built for both standard Category II and the wider Category IIIN sizes.
A Cat II hitch fits most medium to large implements up to about 150 horsepower. The IIIN option offers an even wider connection, making it easier to work with modern equipment that may have a wider stance.
Common Category II implements include plows, cultivators, and larger mowers. For specialty tools or broad implements, the IIIN option increases your choices.
The hitch arms and stabilizers are built strong for tough workloads, giving you a secure attachment point even in rough field conditions.
Lift Capacity @ Ball Ends
The rear three-point hitch lift capacity at the ball ends is up to 14,500 lbs (6,577 kg) for the RT135. If your tractor has a CVT (continuously variable transmission), expect a slightly lower rating, around 12,500 lbs (5,670 kg).
With this high lift capacity, you can operate heavy implements like multi-row planters, large disk harrows, and big round balers without overload. Hydraulic lift cylinders make it possible to smoothly raise and lower loads without abrupt drops or unsafe movements.
The strength at the ball ends means you won’t have to worry about frame stress, even with heavier equipment.
Draft / Position Control
Your RT135 uses electronic lower-link control for both position and draft management. Position control keeps implements at the exact height you set, helpful for mowing, spreading, or grading.
Draft control adjusts implement height automatically when the tractor senses changes in soil resistance. This keeps tillage equipment working at a consistent depth no matter how hard or soft the ground is.
The system allows you to fine-tune sensitivity so that heavy plows or rippers stay exactly where you want, even in uneven or tough fields. With electronic controls, you get better accuracy and easier adjustments from the cab.
Top-Link Sensing (Yes/No)
Top-link sensing is available on the RT135’s three-point hitch. This feature lets the tractor measure the load on the top link as you work.
With top-link sensing, draft control becomes much more accurate, as the system constantly adjusts to changing ground conditions. This helps you maintain the right working depth for fieldwork and reduces wheel slip.
You get more consistent results with less manual intervention. This system is especially useful for large tillage tools and other ground-engaging equipment, as it helps protect the tractor and implement from sudden loads.

Axles & Load Limits
When considering the AGCO RT135 150 hp tractor, it’s important to understand how its axles and load capacities affect performance and safety during heavy jobs. The specifications for front and rear axle loading, as well as the final-drive design, play a key role in daily operations.
| Aspect | Value/Detail | Notes |
|---|---|---|
| Maximum Front-Axle Load | Not specified (see below) | Standard for class |
| Maximum Rear-Axle Load | Not specified (see below) | Supports heavy implements |
| Rear Lift Capacity | Up to 14,500 lbs (6577 kg) | At 24 inches behind hitch |
| Final-Drive Type | Not specified | Heavy-duty, typical for class |
Maximum Front-Axle Load (kg)
The AGCO RT135’s maximum front-axle load is not directly stated in public materials, but you can expect it to be robust for a tractor in the 150-horsepower range. This axle is designed to support the weight from front-end attachments and provide stability during loader work or when traveling with full ballast.
Modern front axles on tractors like the RT135 often use high-strength steel and advanced engineering to resist flexing under stress. For best results, you should avoid overloading the front with attachments heavier than recommended for this tractor’s class.
Always distribute weight evenly when adding weights or using front-mounted tools. Front-axle load limits protect steering components, tires, and axles from premature wear or damage.
Exceeding these limits can shorten the life of your tractor and cause safety issues during operation, especially on uneven ground or when transporting loads at higher speeds.
Maximum Rear-Axle Load (kg)
The rear axle on the AGCO RT135 is built for handling high loads, especially when working with heavy implements or when pulling large loads. While a specific maximum rear-axle load is not provided in the referenced sources, the tractor’s rear lift at 24 inches—the standard measurement point—reaches up to 14,500 lbs (6577 kg).
This impressive lift capacity is ideal if you work with large plows, seeders, or other demanding implements. To maintain performance, ensure the load at the rear hitch or on trailers does not exceed the rated limits.
Rear-axle load affects traction, braking, and overall stability. Distributing weight across both axles, and using the correct tire pressure, will help you achieve safer transport and field performance.
Properly managing rear-axle loads reduces the risk of tipping and preserves the integrity of the axle and drivetrain. Heavy rear weights should be balanced with adequate front ballast, especially when traveling at speed or on slopes.
Final-Drive Type
The final drive of the AGCO RT135 uses a heavy-duty design typical for tractors of its power and size. While specific technical details are not listed in the provided sources, these tractors generally feature planetary or inboard final drives that deliver power smoothly and withstand constant high torque and rough ground conditions.
This type of final drive provides efficient torque transfer from the transmission to the wheels, ensuring reliable traction and decreased drivetrain stress.

Electrical System
The AGCO RT135 tractor features a practical and robust electrical system that supports essential operations for fieldwork and daily activities. Key aspects include the ground setup, alternator design, battery power, and output capabilities.
Ground Type (Negative / Positive)
The AGCO RT135 uses a negative ground electrical system, which is standard for most modern tractors. In a negative ground system, the negative terminal on the battery is connected directly to the chassis of the tractor.
This design improves the efficiency of the electrical circuits. It helps reduce corrosion issues for electrical connections and makes finding replacement parts easier.
You will find it easier to work with testing equipment, accessories, and replacement components, since most tools are designed for negative ground systems. This setup also lowers the risk of polarity-related damage when you hook up additional electrical parts or replace the battery.
Alternator / Charging System
Your AGCO RT135 is equipped with a standard alternator-based charging system. The alternator is responsible for generating electricity while the engine runs.
Its primary role is to keep the batteries charged and run the tractor’s electrical accessories. OEM alternators for the RT135 often come from trusted brands, such as Nippondenso, Bosch, Delco Remy, and Mitsubishi.
These alternators are designed to perform reliably in harsh environments. The alternator’s mounting location allows for access during service, and the drive system usually consists of a belt connected to the engine.
This straightforward design keeps maintenance simple.
Charging Output (Amps)
The alternator on the AGCO RT135 provides a charging output of 120 amps. This high output supports all the major electrical functions and accessories of the tractor.
A 120-amp alternator can easily handle extra lighting, electronic controls, and cab systems. It also supports added implements that require electrical power.
