Steering System (Hydrostatic / Power-Assisted / Mechanical)
Your AGCO Allis 8775 tractor comes with power steering. The system is hydrostatic and electro-hydraulic, which means steering takes very little effort, even with a heavy load or when using front-end attachments.
You control the tractor with minimal force thanks to hydraulic pressure assisting your inputs. This type of system helps you make smooth, precise turns at all speeds.
There is also a differential lock included, which you can activate electronically. It’s helpful for added traction when conditions are slippery or uneven.
You get more control and stability, especially useful in tough field work.
Turning Radius (With Brakes)
The turning radius on the 8775 is tight for a tractor of its size, given its utility in row-crop and loader work. When you apply the brakes on one side, you can make even sharper turns than using the steering alone.
This design helps maneuver in smaller farmyards or headland turns. The turning system, combined with brake assistance, reduces the number of passes you need to make in the field.
You benefit from quick maneuverability, which saves time and reduces soil compaction. Less reversing and repositioning are needed during tight operations.
Service Brakes (Wet Disc, Dry Drum, Etc.)
The tractor uses hydraulic wet disc brakes on the rear axle. Wet disc brakes are known for their reliability and long service life, since the braking surfaces stay lubricated and cool due to being bathed in hydraulic fluid.
These brakes offer smooth stops, even under heavy loads or repeated use. The system allows you to expect consistent performance, lower maintenance, and less risk of brake fade compared to dry drum brakes.
Wet disc brakes are also easier to modulate, so you can make controlled stops in both road and field conditions. This is especially important when moving large implements or fully loaded trailers.
Parking Brake Type
The parking brake on the AGCO Allis 8775 is a mechanical system. You set it manually using a handle or lever in the cab.
Mechanical parking brakes are direct and dependable: once engaged, they lock the brake mechanism so the tractor stays in place. The design has few parts to fail and doesn’t rely on hydraulic pressure.
Your tractor won’t roll if hydraulic pressure drops after the engine is off. This adds to safety during maintenance or when the tractor is parked, especially on inclines.
You can rely on the mechanical parking brake to hold the tractor steady overnight or during extended stops in the field.

ROPS / Cab Option
You can choose between an open ROPS (Roll-Over Protection Structure) or an enclosed cab on the AGCO Allis 8775. The open ROPS is designed for users needing quick on-and-off access and maximum visibility in the field.
It provides basic operator protection during rollovers and is lighter in weight. The enclosed cab option gives you better protection from weather, dust, and noise.
It comes with wide doors and large windows for easy entry and clear sightlines. Controls are within arm’s reach, and lighting is improved for night work.
The cab version adds more comfort, especially for long work hours. The cab was available from the factory, and you can usually identify units with full cab by the sealed glass and roof design.
Climate Control (A/C, Heater, Filter)
If you select the enclosed cab, you also get a climate control system that includes heating, air conditioning (A/C), and filtered airflow. The heater helps you stay warm in cool weather, while the A/C keeps you cool in hot conditions.
Large air vents direct airflow throughout the cab. A built-in air filter system keeps dust and pollen from entering, which is helpful if you work in dry or dusty fields.
The controls are placed on the dash or side panel, and you can adjust fan speed, temperature, and air direction. The heating and cooling system is designed to maintain a steady temperature.
Seat & Suspension
The operator seat in the AGCO Allis 8775 is adjustable to fit your height and reach. It usually includes mechanical or air-spring suspension.
This type of seat absorbs shocks and vibrations from rough ground, keeping you more comfortable. You can adjust the seat position and suspension firmness using simple levers and dials.
Many models also have a swiveling seat for easier turning and better access to rear controls. Armrests and lumbar support can be included for extra comfort.
Proper seat design reduces the risk of back and leg fatigue, which is especially important if you spend many hours per day in the cab. Suspension absorbs most bumps before they reach your body.
Noise Level (Db A @ Operator Ear)
Inside the cab, the noise level typically ranges from 77 to 82 decibels (dB A) at the operator’s ear. This noise comes from the engine, hydraulic pumps, and external conditions.
The cab’s insulation panels and rubber seals help lower interior noise compared to the ROPS version. Lower noise levels make it easier to hear the radio, communicate with others, and reduce fatigue from constant engine sound.
If you choose the open ROPS version, you’ll notice higher noise since there’s no glass or insulation blocking engine and field sounds. Wearing hearing protection is still recommended for extended use, especially when working with implements or at high engine speed.
Hydraulics
The AGCO Allis 8775 uses a versatile hydraulic system to support a variety of implements and attachments. The features focus on consistent flow, reliable pressure, and operator-friendly controls.
System Type (Open-Center / Closed-Center / PFC)
You will find that the 8775 uses an open-center hydraulic system, which means the fluid constantly circulates through the pump when the system is not in use. This is a straightforward, durable system commonly used on tractors in this power range.
The open-center design is easy to maintain, with fewer parts compared to closed-center or pressure-flow compensated (PFC) setups. This layout helps keep your hydraulic functions responsive and minimizes downtime since repairs are simpler and less costly.
With this system, hydraulic oil flows continuously when levers are in neutral. This continuous flow makes it reliable for most farm work, though it may offer less efficiency if you are running several demanding hydraulic functions at the same time.
Implement Pump Flow (L Min⁻¹)
The implement pump on the AGCO Allis 8775 delivers a consistent flow rate suitable for typical loader and implement use. Pump output is approximately 60 liters per minute (L/min).
This flow rate means you can operate most attachments, such as loaders, plows, or balers, without lag or hesitation. If you run multiple hydraulic implements at once, the pump flow should be strong enough for most jobs in this tractor’s class.
You’ll see quick operation of cylinder functions, which helps speed up tasks like lifting or lowering equipment. The pump is gear-driven, which adds to the system’s reliability and ease of service.
Steering Pump Flow (If Separate)
On the AGCO Allis 8775, the steering circuit uses the same hydraulic system as other functions and does not have a separate dedicated steering pump. Instead, the flow is internally divided to prioritize steering when needed.
This means that steering remains light and responsive, even if you are operating other hydraulics at the same time. The tractor uses power steering, so you won’t need a lot of force to steer, even at low speeds or with a heavy front loader.
Hydraulic pressure is always available for steering actions. You may notice only minimal impact on steering effort, even when additional hydraulic implements are running.
Total Combined Flow
Total combined flow for all hydraulic functions on the AGCO Allis 8775 is about 60 liters per minute. This includes both the main implement circuits and steering.
This combined output supports simultaneous tasks, such as using a loader while steering and operating other tools at the rear remotes. The system is optimized to share flow based on demand, so you rarely experience interruptions in power.
If you run high-flow attachments, the total capacity should be considered to prevent slowdowns. For typical farm operations, this combined flow rate is effective and predictable.
System Pressure (Bar / Psi)
The maximum working pressure for the hydraulic system is about 180 bar (approximately 2,600 psi). This level supports strong and consistent operation for a wide range of implements.
At 180 bar, you get sufficient force for heavy lifting, powering rams, and running hydraulic motors on attachments. The system’s pressure is regulated by an internal relief valve to prevent overload, which also protects hoses and valves from damage.
Pressure stability keeps your hydraulic tools working consistently. If you use implements requiring a specific pressure, you can depend on this system to meet most agricultural demands.
Remote Valves (Number & Type)
The AGCO Allis 8775 is commonly equipped with three rear remote valves as standard, though some models may offer different configurations. All are double-acting, which allow oil flow in both directions for operating cylinders in both directions.
You can control each remote independently with in-cab levers. These remotes are suitable for running a variety of attachments, including mowers, seeders, or hydraulic top links.
The valves come with quick-connect couplers for easy attachment changes. The design makes it efficient to switch implements or connect additional hydraulic-powered equipment without tools.

Most modern farm equipment for 100+ horsepower tractors will match with Category II without needing adapters. This hitch category helps you attach and detach implements easily.
Quick-hitch compatibility is often available, saving time during implement changes.
Lift Capacity @ Ball Ends
The rear three-point hitch lift capacity of the AGCO Allis 8775 is about 7,700 pounds (3,493 kg) at the ball ends. This maximum lift capacity allows you to mount large implements without overloading your tractor.
Hydraulic power behind the hitch system ensures that even full loads can be lifted smoothly. Heavy attachments, such as multi-row planters or 3-point mounted sprayers, are supported within this range.
Pay attention to the placement of implements for the safest lifting. Always use the lift capacity rated at the ball ends, not at different points, for the most accurate matching.
Draft / Position Control
You control the height and depth of the three-point hitch using both draft and position control systems. Draft control automatically adjusts hitch height to keep consistent soil engagement for ground-working tools.
Position control lets you set the hitch to a specific height and hold it steady. This is important for tasks like transport or when you need to keep attachments lifted at a set level.
Switching between draft and position control is straightforward with the lever controls in the cab. This setup helps you get better traction and more precise implement performance, especially in varying field conditions.
Top-Link Sensing (Yes/No)
The AGCO Allis 8775 uses top-link sensing for draft control. This feature detects the resistance from the implement through the top link and adjusts the hitch as needed.
Top-link sensing makes draft control more responsive because changes in soil resistance are quickly detected. This helps maintain a steady working depth when pulling tillage tools.
If you work in uneven soils or need consistent performance while plowing or cultivating, top-link sensing improves the overall control and efficiency of your operation. This sensing is standard on the 8775 model.
Axles & Load Limits
The AGCO Allis 8775 offers strong axle support to handle heavy equipment and attachments. Its axle capacities and robust final-drive system are key to safe operation and high performance.
Maximum Front-Axle Load (Kg)

Tires & Track Options
Choosing the right tires is essential for getting the best performance from your AGCO Allis 8775 tractor. Different tire setups affect traction, ride comfort, and the tractor’s ability to work in various field conditions.
Standard Front Tire Size (Ag / Turf / Industrial)
The typical front tire size for the AGCO Allis 8775 is 11.00-16 when equipped for agricultural work (Ag tires). These Ag tires are designed for traction in soft or muddy fields and help minimize soil compaction.
If you plan to use the tractor on grass or lawns, you may use turf tires, which offer a wider contact patch and smoother tread. Turf tires help prevent damage to the surface but are less common as standard equipment for this tractor.
Industrial front tires are available as an option in some markets. These generally have a tough, heavy tread better suited for mixed or hard-surface use but may not offer the same level of traction in muddy conditions.
Always check your tractor’s rim size and compatibility before changing tire types.
Standard Rear Tire Size
Most AGCO Allis 8775 tractors use 16.9R-38 tires on the rear axle as standard equipment. These larger rear tires are crucial for delivering the tractor’s 105 horsepower efficiently to the ground.
The radial design (noted by the “R” in the size) provides good flexibility, better ride comfort, and improved traction. These rear tires are typically Ag types, optimized for soft fields and row-crop work.
If you need to operate on turf or paved surfaces, you can look for turf or industrial rear tire options, but you’ll need to confirm fit and load ratings. Proper inflation is key for maximum traction and tire life.
Always refer to the manufacturer’s recommendations when checking or setting rear tire pressures. Running too low or too high can harm performance or cause premature wear.
Optional Duals / Tracks / Flotation Kits
For heavy pulling or to reduce soil compaction, you can add dual wheels to the rear axle of the 8775. Duals mount another tire alongside the main wheel, spreading weight over a larger area for more stability and less compaction.
Flotation kits are available for working in wet or soft soils. These kits usually include wider tires or special wheels that are designed to “float” over the ground, rather than digging in.
Using flotation tires is best when you need to minimize ruts or ground disturbance. The AGCO Allis 8775 is not commonly fitted for tracks from the factory, but some aftermarket systems allow the installation of rubber tracks in place of rear tires.
Tracks provide excellent flotation and can be helpful in challenging field conditions. They tend to be more expensive and may require additional adjustments to the tractor.
| Option | Front Tires | Rear Tires | Description / Benefit |
|---|---|---|---|
| Standard Ag | 11.00-16 | 16.9R-38 | Best for field traction and general farm use |
| Turf | Varies | Varies | Wide, smooth tread for lawns and minimal surface damage |
| Industrial | Varies | Varies | Durable tread for hard or mixed surfaces |
| Rear Duals | N/A | Dual 16.9R-38 | More stability, reduced compaction for heavy-duty work |
| Flotation Tires / Kits | Wide (optional) | Wide (optional) | Minimized soil impact in wet or soft conditions |
| Tracks (Aftermarket) | — | Rubber Tracks | Best traction and flotation; specialized use cases |

Length matters when you are planning storage or transport. If you are parking the tractor in a barn or moving it on a trailer, you need this exact measurement.
The length also affects stability when you use heavy equipment or loads. Knowing the length in both feet and inches makes it easier to compare with other tractors or check available space in your sheds and trailers.
Overall Width (Minimum Tread)
The overall width at minimum tread is 88 inches (223 cm). This is the narrowest setting for the tractor’s rear wheels, not counting the optional duals or spacers.
Minimum tread width is important when moving between rows, traveling on narrow roads, or loading onto trailers. A width of 88 inches provides a good balance, making the 8775 stable in the field while still narrow enough for many standard gates.
Pay attention to this width if you are using the tractor in areas with limited space or where rows are close together.
Height To ROPS / Cab
The height to the top of the cab (also called to ROPS—rollover protective structure) is 109 inches (276 cm). This is the maximum height and affects the ability to enter low doorways, storage areas, or under trees.
If your barn has low doors, or if you often work under structures or in wooded areas, this measurement is important. Always check your highest point, which is usually the exhaust or cab roof.
The height is high enough to allow good operator visibility and provide room for the ROPS or cab, which protect you during rollovers.
Ground Clearance
Ground clearance is important for working on rough land, but a specific measurement isn’t listed in the main sources. This tractor’s clearance is typical for row-crop tractors in its class, which usually ranges between 17 to 22 inches.
Higher clearance helps you avoid damaging crops when cultivating and protects the parts under the tractor from rocks or stumps.
