Engine Specifications
The AGCO Allis 9635 tractor is powered by a strong Detroit Diesel engine.
Engine size, design, and rated power affect how the tractor performs in the field.
Engine Make & Model
You get a Detroit Diesel 7.6L six-cylinder diesel engine.
This engine is known for reliability and straightforward maintenance.
Detroit Diesel is well established for making strong, long-lasting tractor engines.
Model 9635 uses the “Series 40” engine, which is based on a trusted design.
This engine type is common in tractors that need steady horsepower for heavy work.
It is built for farm work, with a simple layout for easy access to engine parts.
Fuel Type & Emissions Tier
You will be using regular diesel fuel.
The AGCO Allis 9635 was built before current Tier 4 Final emissions rules.
So, it does not have DEF (diesel exhaust fluid) systems or complex emission filters you find in newer tractors.
This engine follows the less-strict emissions levels of its time.
It does not use electronic emissions controls.
The use of diesel allows for good fuel economy and reliability for long days in the field.
Low-sulfur diesel is recommended, but ultra-low sulfur diesel may sometimes be required, depending on fuels available in your region.
Cylinders / Displacement
Your engine is a six-cylinder inline configuration.
Inline-six designs help create smooth power delivery and low vibration.
The displacement is 7.6 liters (466 cubic inches).
Each cylinder has a bore of 4.30 inches and a stroke of 5.35 inches.
This balanced design allows the engine to create strong torque at lower RPMs.
Having a large displacement means the tractor can handle heavy loads, pulling implements, and difficult soils without losing performance.
Rated Horsepower (Gross & Net)
The rated engine output is 150 horsepower.
This figure is the gross horsepower at the engine flywheel and is achieved at a nominal speed of 2,200 rpm.
Net horsepower, which accounts for engine-driven accessories such as fans and alternators, is slightly lower but still close to this figure.
This level of power allows you to use many medium-to-large implements, run PTO-powered tools, and maintain good ground speed on large fields.
Peak Torque (Nm @ rpm)
The Detroit Diesel 7.6L engine delivers high peak torque at lower RPMs.
Peak engine torque is typically available around 530–550 lb-ft (approx. 720–750 Nm) at 1,400–1,600 rpm.
This means your tractor can push through tough soil or climb out of challenging spots without stalling.
The engine’s strong low-end torque helps keep wheels moving even when pulling heavy loads or operating in mud or hills.
Compression Ratio
Your engine features a compression ratio of about 16.5:1–17:1.
This high compression is common in diesel tractor engines.
High compression ratios improve fuel efficiency and increase the power output of every combustion cycle.
With this compression, the engine starts well in cold weather as long as you use the correct starting aids (such as ether injection).
The high ratio also means you must use good quality diesel fuel and avoid contaminants in the tank.
Cooling System & Capacity
The AGCO Allis 9635 uses a liquid-cooled system with a robust radiator and a belt-driven water pump.
This ensures that the large 7.6L engine stays within safe temperature ranges during long days of work.
Cooling capacity is important for a tractor of this size.
The system holds enough coolant to offer steady cooling even under heavy loads.

This power enables most heavy-duty PTO tasks on the farm.
The engine itself is rated around 150 hp, but not all of it is available at the PTO due to power losses through the drivetrain.
You can expect strong, steady performance at both main PTO speeds.
For field use, the consistent PTO output helps reduce lugging and provides a steady experience, even under load.
Proper maintenance is important to help keep your PTO power output close to its rated value.
PTO Type (Independent / Live / Economy)
The PTO on the AGCO Allis 9635 is independent.
This means the PTO is operated by a separate clutch system, allowing you to start or stop the PTO without stopping the tractor’s forward movement.
You do not need to depress the main clutch, which is helpful when operating machines like balers or spreaders that should only run at specific times.
This independent system is managed by a hydraulic wet disc clutch, offering smoother engagement and longer life than dry clutch setups.
It is also less likely to overheat or wear quickly.
There is no economy PTO on the 9635, so you always use standard PTO speeds.
By using an independent PTO, you can switch implement power on or off immediately when needed, making the tractor more versatile in the field.
PTO Speeds (540 / 1 000 rpm)
The AGCO Allis 9635 features a dual-speed rear PTO with both 540 and 1,000 rpm options. This versatility lets you operate a broader range of implements.
Each speed is selected by a mechanical lever, and both use a standard 1-3/8 inch shaft.
- 540 rpm: Used for lighter or older equipment, small mowers, or specific balers that need the lower speed.
- 1,000 rpm: Ideal for larger, high-power implements such as newer balers and bigger rotary cutters.
Most users find that the selector lever is positioned conveniently, making it quick to swap speeds as you change attachments.

The top transport speed for the AGCO Allis 9635 is typically in the range of 18–25 mph (about 29–40 km/h), depending on tire size, transmission setup, and market regulations.
You can expect to get from the field to the yard or job site with less downtime, which matters during busy seasons.
Transport performance is further improved by powershift operation, allowing you to safely change gears on the move without slowing down or stopping.
Drive (2WD / 4WD / AWD)
The AGCO Allis 9635 comes with an MFWD (Mechanical Front Wheel Drive), often called 4WD or AWD (All Wheel Drive). Both the front and rear axles receive power.
With 4WD, you get better traction, especially on wet, soft, or uneven ground. This is helpful for turning, pulling implements, and keeping steady movement in poor soil.
You can engage or disengage front-wheel drive, depending on the task. Field work with heavy equipment usually needs 4WD, while lighter road use may use just rear-wheel drive.
Differential-Lock & Final Drives
The tractor features a differential lock that can be engaged when extra traction is needed, like when one wheel begins slipping in mud or loose soil. This locks both rear wheels together to spin at the same speed, making it easier to power out of a sticky spot.
A final drive system in the AGCO Allis 9635 delivers torque to the wheels through planetary gears positioned in the axle housing. These gears lower the speed and increase the torque, reducing stress on the axles and drivetrain.
You can activate the differential lock with a foot pedal or switch. Always disengage it before making sharp turns to prevent drivetrain damage.

Steering System (Hydrostatic / Power-Assisted / Mechanical)
The AGCO Allis 9635 uses a hydrostatic power steering system. This setup gives you easy steering with very little effort, even when the tractor is fully loaded or moving at low speeds.
With power-assisted steering, you can make quick adjustments and keep control over the tractor, which is especially helpful during long work days or while making frequent turns in the field. You’ll notice that the steering wheel turns smoothly, and you don’t need to use extra force.
This type of steering improves comfort and reduces fatigue for the operator. The hydraulic system automatically adjusts to the load, giving you the right amount of assistance exactly when you need it.
Turning Radius (with brakes)
The AGCO Allis 9635 delivers a tight turning radius for its size, especially when you use the brakes to help turn. By applying the left or right brake, you can make sharper turns which are very useful in smaller fields or when working near obstacles.
This feature allows you to work efficiently in spaces that might otherwise be tough to navigate with a large tractor. The ability to pivot tightly cuts down on the time you spend repositioning the machine.
With the brakes assisting your turns, you can maintain a higher level of accuracy. The steering and brake system together provide enhanced maneuverability in demanding field conditions.
Service Brakes (Wet Disc, Dry Drum, etc.)
The service brakes on the 9635 are usually wet disc brakes. These brakes are sealed in oil, which helps keep them cool and reduces wear over time.
Wet disc brakes are known for their long life and reliable stopping power, even in muddy or wet conditions. The design also keeps out dirt and debris, which means less maintenance for you and fewer chances of brake failure in tough conditions.
The brake pedals are split, letting you control the left and right brakes independently. This setup allows for more precise turning and better control when you need it most.
Parking Brake Type
The parking brake on the AGCO Allis 9635 is typically an internal mechanical system, often using the same discs as the service brakes but with a separate locking mechanism. When you engage the parking brake lever, it locks the brakes securely so your tractor stays in place.
You can count on the parking brake to hold the tractor steady, even on slopes or when you’re leaving it attached to heavy equipment. The system is simple to use—just pull up on the lever and the parking brake engages right away.
This brake is built for safety, helping prevent rollaways in all environments.

The cab is made from strong materials to provide rollover protection in case of an accident, meeting key safety standards for farm equipment. The doors and windows are sealed well, helping to keep out noise, dust, and weather.
You can access the cab using wide, non-slip steps and firm handrails. Visibility is a strong point, with large windows that give you a clear view on all sides, reducing blind spots.
The cab is tall enough for most operators to move and turn without trouble, which lowers fatigue.
Climate Control (A/C, Heater, Filter)
Inside the 9635 cab, you get a complete climate control system with air conditioning, a powerful heater, and a cab air filter. The air conditioning system uses a refrigerant circulation unit, and some models include a thermostatic switch to regulate the temperature.
Large air vents are placed around the cab for even distribution. The heater pulls from the engine coolant, sending warm air through the vents quickly on cold days.
An air filter keeps most dust and pollen out, improving air quality and helping prevent allergies or respiratory problems in the cab. All control switches for the climate system are close to your seat, letting you adjust settings without taking your attention from the job.
The cab is sealed well, which supports efficient climate control and keeps the inside air cleaner.
Seat & Suspension
Seating in the 9635 is designed for comfort and support during long hours. The main seat has adjustable suspension to absorb shocks and bumps from rough fields or roads.

Hydraulics
The AGCO Allis 9635 features a powerful hydraulic system suited for demanding fieldwork using modern implements. Its system components provide strong flow rates, reliable pressure, and enough remotes to manage a wide range of farming equipment.
| Hydraulic Feature | Specification / Detail |
|---|---|
| System Type | Pressure Flow Compensated (PFC) |
| Implement Pump Flow | Approx. 110 L/min (29 GPM) |
| Steering Pump Flow | Separate pump; specific value not published |
| Total Combined Flow | Over 110 L/min (implement + steering) |
| System Pressure | About 200–210 bar (2900–3050 psi) |
| Remote Valves | 2-4 rear, double-acting, electro-hydraulic control |
System Type (Open-Center / Closed-Center / PFC)
The 9635 uses a Pressure Flow Compensated (PFC) hydraulic system. This design provides precise control by delivering oil where and when it is needed based on demand instead of running full output all the time.
With a PFC system, you get faster response for loader work or changing implement needs. The system reduces power loss because it only uses as much oil flow as needed.
This also helps keep hydraulic oil cooler and reduces wear on the pump. A PFC system is preferred over open-center layouts for tasks that need multiple functions at once, such as running several hydraulic remotes while also raising or lowering an implement.
You may notice quieter operation and more consistent hydraulic force as demand increases or decreases.
Implement Pump Flow (L min⁻¹)
The AGCO Allis 9635 is equipped with an implement pump rated at about 110 liters per minute (approximately 29 gallons per minute). This high flow rate ensures you can operate large implements, such as air seeders or modern planters, that require steady and strong hydraulic supply.
If you are using demanding attachments like hydraulic motors or large cylinders, this amount of flow minimizes delays and keeps work moving quickly. Large implements with multiple actuators benefit from faster cycle times for lifting, extending, or folding.
Hydraulic flow of 110 L/min also gives you flexibility to power several smaller tools at once without slowing down.
Steering Pump Flow (if separate)
The steering system on the AGCO Allis 9635 uses a dedicated pump that is separate from the main implement hydraulics. This helps guarantee smooth and unaffected steering performance no matter how much hydraulic demand is placed on other systems.
A separate steering pump ensures steering is always prioritized, providing both power steering and safe operation. If you are running high-demand implements, you will still have responsive steering at all engine speeds.
The specific flow rate is not widely published, but it is designed to match the tractor’s size and weight. Routine operation, even with maximum hydraulic use elsewhere, will not cause steering delays or heaviness.
This is especially important if you transport heavy trailers, use front loaders, or make tight turns at the end of rows.
Total Combined Flow
When considering both the implement and steering pumps, your total available hydraulic flow exceeds 110 liters per minute. The main implement pump supplies most of this capacity, while the steering system has its own pump to provide uninterrupted function.
Having separate hydraulic circuits for steering and implement reduces the risk of “lag” or sudden drop in performance during demanding work. Total flow is especially important for operating attachments with both hydraulic motors and cylinder actions, such as planters with hydraulic-driven fans.
System Pressure (bar / psi)
The system operates at a maximum pressure of approximately 200 to 210 bar, which equals about 2900 to 3050 psi. High-pressure capability ensures that hydraulic functions are powerful and can overcome heavy loads or stubborn implements.
Stable high pressure also improves performance of hydraulic remotes connected to modern tools. For example, it allows for the use of down-pressure systems on planters and keeps loader arms moving smoothly under full load.
With pressure held by the PFC system, you’ll notice fewer drops in force even with multiple solenoids open at once.
Remote Valves (number & type)
The 9635 typically includes two to four rear remote valves. Each valve is double-acting and controlled electro-hydraulically from the cab.
The number of remote valves you have depends on the tractor’s configuration and setup at purchase. These remotes allow you to operate a sizable range of implements, such as row markers, fold systems, hydraulic motors, or transport wheels.
Electro-hydraulic controls provide fingertip convenience and quicker adjustments compared to mechanical levers. Each remote comes with its own set of couplers, making it easy to connect and disconnect attachments without spilling oil.
Having extra remotes increases your flexibility on the farm, letting you switch implements quickly and handle multiple jobs throughout the day.
Three-Point Hitch (3PH)
The AGCO Allis 9635 tractor offers a strong and versatile three-point hitch system with features made for heavy-duty work. You can connect a wide range of implements and gain precise control over lifting and lowering tasks.
Hitch Category (1 / 1N / 2 / 3)
The AGCO Allis 9635 is equipped with a Category 3 three-point hitch, which supports large and heavy implements commonly used in field operations such as plowing, planting, and cultivating. Category 3 hitches use pins that are 1 1/4 inches (32 mm) in diameter for both the top link and lower lift arms.
This category is meant for higher-horsepower tractors like the 9635 and is compatible with most heavy-duty agricultural tools. The robust construction reduces flexing under load, letting you handle larger implements with better stability and safety.
Category 3 hitches are not compatible with smaller Category 1 or 2 implements unless adapters are used. The configuration is suitable for row crop operations, hay equipment, and large planters.
You should always check implement compatibility before attachment.
Lift Capacity @ Ball Ends
The lift capacity of the three-point hitch is one of the key specifications for matching implements to your tractor. The AGCO Allis 9635 typically features a lift capacity at the ball ends of about 8,000 to 10,000 pounds, depending on optional equipment or configuration.
This level of lift capacity allows you to operate with heavier and wider implements, ensuring effective ground engagement and operation on rugged terrain. High lift capacity is ideal for subsoilers, large discs, and big grain drills.
For safety, always keep the implement weight within the hitch’s rated limit. Too much weight can affect stability and steering, especially on hills or during transport.
Draft / Position Control
The draft and position control system on the AGCO Allis 9635 three-point hitch ensures you get precise regulation of implement depth and height. Draft control automatically raises or lowers the implement based on changes in soil resistance.
This is beneficial when plowing, as the system keeps the implement at a steady working depth even if soil conditions change. Position control lets you manually set and keep the hitch at a desired height.
This is useful when operating equipment that needs to stay at the same position above the ground, like mowers or sprayers. These features help improve field consistency, save time on adjustments, and preserve soil structure by reducing unnecessary lifting or pressure.
Top-Link Sensing (Yes/No)
The AGCO Allis 9635 includes top-link sensing. This system detects forces on the top link of the hitch and feeds this information to the draft control system.
As a result, the tractor responds more quickly to changes in load, adjusting the hitch for steady implement depth and smooth operation across variable field conditions. Top-link sensing enhances traction, especially during heavy tillage.
It also helps reduce wheel slip and increases fuel efficiency since less power is wasted. Operators working in mixed or rough soils benefit from top-link sensing because it provides a consistent depth and helps protect implements from sudden stress.
| Feature | Details |
|---|---|
| Hitch Category | Category 3 (1 1/4″ pins, heavy-duty implements) |
| Lift Capacity @ Ball Ends | 8,000–10,000 lbs (depends on setup) |
| Draft Control / Position Control | Both systems standard for depth and height control |
| Top-Link Sensing | Yes; improves draft response and depth consistency |
Axles & Load Limits
Understanding the axles and load limits is important for getting the best performance and safety from your AGCO Allis 9635. Key specifications for the front and rear axles, along with the final-drive system, make a direct impact on how much weight the tractor can safely support and how it moves power to the ground.
Maximum Front-Axle Load (kg)
The front axle is designed to support the weight from the front-end loader, ballast, and front-mounted implements. For the AGCO Allis 9635, the maximum front-axle load typically ranges between 4300 to 4800 kg, depending on factors like front tire size and optional equipment.
You should always check the manufacturer’s specifications, especially if using the 4WD version. Using the weight limits properly prevents excess wear and lowers the risk of axle damage.
Avoid overloading with heavy front attachments or stacked weights so you do not compromise steering and braking. If you frequently use a loader or heavy front implements, spread loads evenly across the axle and check tire inflation regularly.
This helps you keep both handling and safety in check during operation.
Maximum Rear-Axle Load (kg)
The rear axle bears most of the tractor’s working load, especially when pulling large implements or transporting heavy trailers. For the AGCO Allis 9635, the maximum rear-axle load is often set between 7000 and 7600 kg.
Always use rear weights or ballast carefully and avoid overloading beyond factory-recommended limits. Overloading the rear axle can cause axle housing damage, wheel slippage, and reduced braking efficiency.
If using dual wheels or additional ballast, factor in the total combined weight for safety and performance. Pay attention to field conditions.
Operating on slopes or with large planters adds to rear axle strain. Regular checks and proper maintenance will extend axle life and reduce repair costs.
Final-Drive Type
The final drive is responsible for transferring the engine’s power to the wheels efficiently. The AGCO Allis 9635 uses a planetary final-drive system, which is designed for high torque and durability.
