Engine Specifications
You get a reliable turbocharged diesel engine with solid power output. The AGCO Allis 8745 offers practical design details and proven components.
Engine Make & Model
The AGCO Allis 8745 tractor features a diesel engine built by SisuDiesel, sometimes referenced in the industry as Sisu or SisuDiesel 4.4L. This engine is well-known for its reliability and durability in farming conditions.
Some models may also use a Cummins 3.9L option, but the Sisu 4.4L is more commonly found in the 8745 series. Sisu, based in Finland, produced engines widely respected for smooth operation and fuel efficiency.
Your tractor will benefit from this reputable engineering, giving it a long working life and less downtime. The 8745’s engine is liquid-cooled and turbocharged, which helps extend the lifespan and improve performance during heavier tasks.
A turbocharged setup means more air and fuel can enter the combustion chamber, boosting both power and efficiency. You can expect consistent starts and responsive acceleration, even under load, thanks to the precise engineering of this four-cylinder diesel.
Fuel Type & Emissions Tier
The AGCO Allis 8745 runs exclusively on diesel fuel. Diesel engines are popular in this power range because of their better torque and fuel economy compared to gasoline engines.
The fuel tank capacity ranges from 33 gallons (124.9 liters) for open ROPS versions to 37 gallons (140.0 liters) for cab versions. This larger capacity means fewer stops for fuel during long workdays.
This tractor was manufactured before the implementation of strict Tier 3 and Tier 4 emission standards, so it does not have advanced after-treatment systems like DEF (diesel exhaust fluid), particulate filters, or catalytic converters. That means less maintenance regarding modern emissions components, but emissions levels will be higher than state-of-the-art models.
Using straight diesel without additives or alternative fuels, you won’t have to worry about emissions regeneration cycles or the hassle of managing emission fluid additives. This design simplifies operation and service.
Cylinders / Displacement
Your AGCO Allis 8745 uses a 4-cylinder configuration, giving it a balance between compact size and effective power delivery. This engine has inline cylinders, which are noted for smoothness and easy servicing.
The displacement is 4.4 liters, or 268 cubic inches, which is on the larger side for a 4-cylinder tractor engine in this class. Large displacement means strong low-end torque and the ability to handle bigger implements without stalling under load.
This four-cylinder, 4.4L block is liquid-cooled, so overheating is rarely a concern with proper maintenance. The engine’s bore measures 4.25 inches and the stroke is 4.72 inches.
This long-stroke design is ideal for tractors because it maximizes torque at lower RPMs, giving you more pulling power while reducing wear from higher revs.
Rated Horsepower (Gross & Net)
The AGCO Allis 8745 is rated for 77 horsepower at the engine, which refers to its gross horsepower. This horsepower rating ensures efficient operation with a variety of implements, such as mowers, balers, and loaders.
Its PTO (power take-off) horsepower is 70 hp, meaning that’s the usable power available for attached implements. The net horsepower is slightly lower than the gross horsepower figure due to internal friction and losses from running auxiliary components like the cooling fan and alternator.
This horsepower output puts the AGCO Allis 8745 in the upper-mid class for utility tractors, making it suitable for heavy mowing, tillage, or hauling workloads. You have enough power overhead to handle hills or wet soil without the engine bogging down.
Peak Torque (Nm @ Rpm)
The engine produces solid torque at lower revs, making it capable of pulling and pushing heavy loads. While specific numbers vary, the peak torque is usually in the range of 300-320 Nm (Newton-meters), achieved between 1400 and 1800 RPM.
This strong low-end torque provides better performance in tough field conditions, such as plowing or discing. It also means you can maintain speed even as the load increases, without frequent shifting.
High torque at lower RPMs improves fuel efficiency and reduces strain on the drivetrain. Most operators notice less engine lugging and a consistent power feel through the operating range.
Compression Ratio
The SisuDiesel engine in the AGCO Allis 8745 has a compression ratio of approximately 16.5:1. Compression ratio is the measure of how much the fuel-air mixture is squeezed inside the cylinder before ignition.
A higher compression ratio increases diesel combustion efficiency and helps produce more torque. At 16.5:1, your tractor’s engine delivers robust performance without requiring premium diesel or additives.
This ratio also plays a role in easy cold starting and lower fuel consumption. Diesel engines with high compression ratios ignite the air-fuel mix using only heat from compression, which means fewer issues when starting in cold weather.
Cooling System & Capacity
Your AGCO Allis 8745 uses a liquid-cooled system. This design helps maintain engine temperature even during extended periods of heavy use.
Cooling is managed by a radiator, a water pump, and coolant passages inside the engine block and head. The cooling system’s total capacity is typically in the range of 12 to 15 liters.
This large capacity ensures the engine does not overheat in hot environments or when running continuously for hours. Regular maintenance is important to keep the system free of debris and check coolant levels.
The coolant must be checked periodically, and it is important to use the correct type recommended by the manufacturer. Always monitor the temperature gauge during use, particularly in high-load situations or extreme weather.

Power Take-Off (PTO)
The AGCO Allis 8745 is designed with farmers in mind, supporting a wide range of PTO-driven tools. You get reliable power and different PTO options to fit various implements and tasks.
Claimed PTO Horsepower
You can expect about 77 PTO horsepower from the AGCO Allis 8745. This is the manufacturer’s rating and reflects how much usable power reaches your implements at the PTO shaft.
PTO horsepower is often lower than engine horsepower due to power lost through the drivetrain. This 77 hp rating gives you enough strength for heavy tasks like running rotary cutters, balers, and grain augers.
Use this rating to help match your tractor to tools with higher power needs. It helps ensure that you don’t overload the tractor or the implement.
PTO Type (Independent / Live / Economy)
The AGCO Allis 8745 uses an independent PTO. This means you can engage or disengage the PTO shaft from a separate control, without needing to stop the tractor or disengage the transmission.
An independent PTO gives you more control and flexibility. When you operate attachments like mowers or balers, you can start and stop the PTO instantly while still moving the tractor.
This setup leads to faster, safer, and more precise work, especially with tasks that require frequent stopping. The independent PTO on this tractor is rear-mounted, making it compatible with most standard tractor implements.
PTO Speeds (540 / 1 000 Rpm)
This tractor gives you two rear PTO speed options: 540 and 1,000 RPM. You can change speeds depending on what your implement requires, making the tractor more versatile.
Most equipment for hay, mowing, and lighter tillage work uses 540 RPM. Heavier or commercial tools, like large balers or grain carts, often need the faster 1,000 RPM setting.
The output shaft size is standard: 1.375 inches, which fits many common implements. Switching between 540 and 1,000 RPM usually involves changing the shaft or flipping a lever, letting you adapt quickly.

Transmission & Drivetrain
The AGCO Allis 8745 offers a practical transmission, several drivetrain options, and useful features for different conditions. Its setup gives you control over speed, traction, and reliability for field and transport work.
Transmission Type (Syncro, Powershift, CVT, HST)
You get a synchronized manual transmission with the AGCO Allis 8745. The gearbox has gears you shift using a clutch and gear stick.
This setup is direct and dependable, letting you change gears smoothly with proper timing. The clutch is a traditional mechanical type.
It engages and disengages the drive to the transmission, so you can shift or stop without stalling the engine. Syncro shifting allows for easier gear changes compared to older unsynchronized gearboxes.
This tractor does not use a powershift, continuously variable (CVT), or hydrostatic (HST) transmission. That keeps things simple with less electronics or hydraulics to maintain.
Number Of Gears / Ranges
You work with a 12-speed transmission on most versions of the AGCO Allis 8745. This means there are 12 forward gears arranged in multiple ranges.
Some models offer a shuttle for quick direction changes, especially helpful during loader work. Gears are typically arranged in three main ranges, each with four gears.
This lets you select speeds for heavy tilling, lighter work, or road travel. The range lever and gear stick are within easy reach so shifting is straightforward.
A reverse gear set is included, generally matching the forward gears for speed and convenience. The configuration gives you flexibility for many farming tasks.
Top Transport Speed
The top speed for the AGCO Allis 8745 depends on the tires and transmission setup. On average, you reach between 18 and 22 mph (around 29–35 km/h) on the road.
This speed range is enough for moving between fields, driving on public roads, or hauling equipment. The direct mechanical drive means less power lost to slippage, so you get consistent road speeds.
For safety, make sure the brakes and steering are in good condition before operating at maximum speed. Use road mode and lower ranges for hilly or uneven terrain to maintain control.
Drive (2WD / 4WD / AWD)
The AGCO Allis 8745 comes in both 2WD (rear wheel drive) and 4WD (Mechanical Front Wheel Drive, sometimes marked MFWD) versions. You can choose based on your needs for traction and field conditions.
A 2WD version is lighter and uses less fuel, suited for flat land and lighter tasks. The 4WD/MFWD model adds a driven front axle, improving grip and reducing wheel slip, especially on soft or wet ground.
Switching between 2WD and 4WD is typically done with a mechanical lever or switch near the operator seat. This gives you flexibility for different jobs and surfaces during the day.
Differential-Lock & Final Drives
You have a differential-lock on the rear axle of the 8745. It’s usually engaged by stepping on a dedicated pedal or flipping a lever.
The lock gives both rear wheels equal turning power. This is handy when one wheel starts to slip in mud or on soft earth.
Final drives are planetary or bull gear type, designed for high torque and long life. The robust build helps transfer power from the transmission to the axles while keeping maintenance needs low.
Use the differential-lock only when needed, because using it on hard surfaces can cause wear or handling issues. Release the lock as soon as you’re back on solid ground.

Steering & Brakes
This tractor features a hydrostatic power steering system, a compact turning radius with brake assistance, reliable wet disc service brakes, and a secure parking brake setup. Each part of the steering and braking system has been engineered for control, safety, and low maintenance.
Steering System (Hydrostatic / Power-Assisted / Mechanical)
The AGCO Allis 8745 uses a hydrostatic power steering system. You get smooth and easy wheel movement, even when handling heavy implements or working at low speeds.
Hydrostatic steering means hydraulic fluid pressure assists your steering inputs. This results in reduced steering effort and less fatigue during long work days.
There are no mechanical linkages connecting your steering wheel directly to the wheels. Instead, sensors and valves control hydraulic flow to help you turn the wheels.
This system is reliable and requires less maintenance compared to older power-assisted or mechanical designs. Power steering is especially useful in tight areas or when you need to make frequent adjustments.
The steering mechanism is well-protected from dust, dirt, and debris, which helps extend its working life.
Turning Radius (With Brakes)
Turning the AGCO Allis 8745 is efficient because the turning radius is minimized with brake assistance. By engaging the turning brakes, you can pivot tighter around obstacles.
This feature helps a lot during headland turns or in compact fields. Braking on one wheel causes the tractor to rotate more sharply towards that side.
It lets you navigate narrow areas without excessive backing up. This is very important for row crop or loader work, where precision is key.
When both four-wheel and two-wheel drive versions are available, the turning radius may differ slightly. However, both configurations allow for effective maneuvering, thanks to the hydraulic steering and brake assist.
Service Brakes (Wet Disc, Dry Drum, Etc.)
The 8745 tractor uses hydraulic wet disc brakes on the rear axles. Wet disc brakes are immersed in a bath of oil, which keeps them cool and reduces wear during hard or repeated braking.
These brakes are known for their smooth engagement and long service life because the oil helps prevent heat buildup. Wet disc brakes are well-sealed from moisture and dirt, making them suitable for muddy or dusty conditions common on farms.
The hydraulic actuation means that you control braking pressure with less physical effort. This design gives you steady response and reliable stopping power, even with heavy loads or on slopes.
Unlike dry drum brakes, wet discs do not squeal or fade as easily. They also need less frequent adjustment.
If a problem does arise, the modular construction allows for accessible maintenance. The 8745’s brake discs have metallic linings, which enhances durability.
Parking Brake Type
The parking brake on the AGCO Allis 8745 is a mechanical hand-lever system, often using a spring-loaded mechanism to keep the brake engaged when parked. This system is simple to operate; you pull the lever to activate the brake and lock the tractor in place.
A positive-lock design ensures the tractor will not roll, even if parked on a slope or with equipment attached. The system is mechanically independent from service brakes, so it will hold the tractor even if there are hydraulic issues.
Routine checks on the cable and spring mechanism are all that’s needed to maintain this system. The spring-loaded design means the brake will not release until you disengage the lever.
| System Part | Type / Design | Key Features | Maintenance Notes |
|---|---|---|---|
| Steering | Hydrostatic (Power Steering) | Smooth, low effort control; no mechanical linkage | Low maintenance; sealed system |
| Turning Radius | With Brake Assist | Tight maneuvering; effective in row crops/loader work | Adjusts with 2WD/4WD config |
| Service Brakes | Hydraulic Wet Disc (Metallic Lining) | Cool running, long life, well-sealed, resist fade/squeal | Occasional fluid check; durable |
| Parking Brake | Mechanical Hand Lever, Spring-loaded | Safe, positive lock, simple design, holds during repairs | Periodic cable/spring inspection |
Cab & Operator Station
You can expect a practical, comfortable setting when operating the AGCO Allis 8745. Each feature helps make long hours easier and more productive for the driver.
ROPS / Cab Option
You can choose between an open ROPS (Rollover Protective Structure) or an enclosed cab for the AGCO Allis 8745. The ROPS configuration gives full protection if the tractor tips and maintains an open-air setup for ventilation.
This is useful for short tasks or when working in hot conditions. The enclosed cab option increases operator comfort by shielding you from weather, dust, and debris.
A cab also adds integrated lighting, wipers, and more secure entry and exit. If you work long hours in variable weather, a cab can offer significant advantages for health and safety.
Both setups are designed for easy entry and a clear view of your surroundings. Cab-equipped models are heavier than ROPS units, which can affect weight distribution and handling.
Choosing between ROPS and cab depends mainly on your climate and job needs.
Climate Control (A/C, Heater, Filter)
If you select the enclosed cab, your tractor comes with standard climate control features. Air conditioning and a heater ensure you can work in both hot summers and cold winters.
The air conditioner cools the space quickly and evenly, keeping you dry and alert even during long days. A quality heating system helps keep you comfortable in freezing temperatures.
You can expect a multi-speed fan and directional vents, allowing you to aim warm or cool air as needed. All cab models include air filtration, which keeps dust, pollen, and other contaminants out of the cab interior.
This improves air quality and reduces fatigue and allergies. Regular filter maintenance is needed for best results.
Seat & Suspension
You get an adjustable seat with thick padding and ergonomic support. Most models come with mechanical or optional air suspension that helps smooth out the ride over rough ground.
The seat height, backrest, and slide position can be changed to fit most body sizes and operator preferences. A sturdy armrest and accessible controls let you work comfortably for hours.
Vibrations and shocks from the tractor are absorbed by the suspension system, making it much easier to avoid back and joint pain. The material is easy to clean and resists wear.
Lumbar support is standard for extra comfort.
Noise Level (Db A @ Operator Ear)
Cab versions of the AGCO Allis 8745 are insulated to minimize the noise reaching your ears. This limits fatigue and makes it easier to focus on important tasks or use a radio.
The typical noise level for tractors of this class with an enclosed cab is between 75 and 80 dB(A). The open ROPS configuration does not have sound insulation, so noise levels are usually higher, often above 85 dB(A).
Long exposure in this environment may require hearing protection, especially during heavy engine work or when using PTO-driven implements. The noise rating can be affected by cab sealing, window condition, and the use of soundproof materials.
Routine maintenance of cab seals and windows helps keep noise levels as low as possible.
| Feature | ROPS Open Station | Enclosed Cab |
|---|---|---|
| Operator Protection | Rollover structure | Rollover + Weather |
| Climate Control | None | A/C, Heater, Filter |
| Seat | Mechanical suspension | Mechanical/Air option |
| Noise Level (dB A) | 85+ | 75 – 80 |
| Visibility | Excellent, open view | Good, sealed windows |
| Weight | Lower | Higher |
| Comfort | Basic, weather exposed | High, climate controlled |
| Air Filtration | None | Standard |
Hydraulics
The AGCO Allis 8745 tractor uses a robust hydraulic system built for utility and versatility. This section breaks down the major features like system type, main flow rates, pressure levels, and remote valve support.
| Feature | Specification | Details |
|---|---|---|
| System Type | Open-Center | Simple, reliable operation |
| Implement Pump Flow | 67 L/min (manufacturer claimed) | Was not fully met in independent testing |
| Steering Pump Flow | Integrated with main hydraulic system | No separate pump for steering |
| Total Combined Flow | Up to 67 L/min | Shared between implements and steering |
| System Pressure | 180-200 bar (approx. 2600-2900 psi) | Industry-standard for mid-size tractors |
| Remote Valves | Up to 3, double-acting | Allows use of multiple hydraulic implements |
System Type (Open-Center / Closed-Center / PFC)
The hydraulic system in your AGCO Allis 8745 uses an open-center design. This means hydraulic oil continuously flows through the valve and returns to the reservoir when not in use.
The system is always circulating, allowing instant pressure availability. This type is straightforward, dependable, and easier to maintain compared to more complex closed-center or pressure-flow compensated (PFC) systems.
For most farming and loader tasks, open-center hydraulics provide enough performance. However, constant flow may slightly reduce overall efficiency when many controls are activated at once.
You do not need special training to service or operate this system. Common repairs and checks can be done with basic tools and basic hydraulic knowledge.
Implement Pump Flow (L Min⁻¹)
The manufacturer claims an implement pump flow of 67 liters per minute (L/min) for the AGCO Allis 8745. This figure gives you a good upper limit for the speed and force your hydraulic implements can achieve.
Testing from the Nebraska Tractor Test found that the system did not always meet the full 67 L/min. Real-world conditions and accessory demand may lower actual flow, especially for heavy use or multiple operations at once.
For most applications like loaders, mowers, or balers, the flow is usually enough to operate cylinders at a reasonable speed. If you attach very demanding implements, performance may drop slightly.
Steering Pump Flow (If Separate)
On this tractor, the steering and implement hydraulics share the same pump and reservoir. There is no separate steering circuit or pump, which is common for tractors in this power class.
This combined design allows you to use the same hydraulic oil everywhere, but if you are using multiple hydraulic operations at once, steering can briefly feel a bit heavier or slow. Unless you are running several hydraulic levers at full demand, steering usually stays light and smooth.
You don’t need to bleed or service a separate circuit for steering, simplifying maintenance and reducing the risk of leaks.
Total Combined Flow
The total combined flow is up to 67 L/min, shared by all hydraulic functions, including implements and steering. When running a loader or rear-mounted hydraulic tool, you pull from the same capacity as the steering system.
If you operate three functions at once—like loader lift, tilt, and steering—you may notice a small lag. For most field tasks or loader work, this capacity is more than adequate.
If you need to run high-demand tools, you may sometimes wait for full cylinder extension or retraction, but the wait is usually short.
System Pressure (Bar / Psi)
The AGCO Allis 8745 hydraulic pressure is around 180 to 200 bar (about 2,600 to 2,900 psi). This pressure is typical for utility tractors in this horsepower range.
The available pressure allows you to lift heavy implements, use large cylinders, or operate ground-engaging tools with confidence. Most modern hydraulic cylinders and attachments are designed to work well within this pressure range.
Remote Valves (Number & Type)
Your tractor can be equipped with up to three double-acting remote valves as standard. Double-acting valves allow oil to flow in both directions for raising/lowering or extending/retracting cylinders.
These remotes let you run a wide range of attachments such as mowers, loaders, hydraulic rakes, or specialized implements. Each remote has separate couplers, usually located at the rear, and can be easily reached for quick connection or disconnection.
The system is compatible with standard agricultural quick-connect hydraulic tips, making it simple to attach most modern implements without adapters or modifications. You can operate several implements at the same time, as long as total system flow is not exceeded.
Three-Point Hitch (3PH)
The AGCO Allis 8745 comes with a robust three-point hitch system designed for efficient use with modern implements. It supports heavy attachments and offers versatile control for working with many types of equipment.
| Feature | Specification |
|---|---|
| Hitch Category | Category II |
| Lift Capacity @ Ball Ends | ~5,000-5,500 lbs (Approximate) |
| Draft / Position Control | Electronic 3-point hitch with position control |
| Top-Link Sensing | Yes |
Hitch Category (1 / 1N / 2 / 3)
The AGCO Allis 8745 is equipped with a Category II three-point hitch. This hitch size fits implements with larger pins and heavier frames, so you can use more demanding farm tools.
Most Category II equipment uses 1-1/8 inch lift arm pins and offers a sturdy connection to common implements like bigger plows, mowers, and tillers. You can connect both older and new equipment, as most modern machinery in this power range supports Category II.
Category II hitches are favored for utility tractors at this horsepower, offering good flexibility and support for a wide range of jobs. If you plan to use light, Category I implements, you will need a bushing kit to adapt the pins.
Lift Capacity @ Ball Ends
The lift capacity at the ball ends for the AGCO Allis 8745 three-point hitch is about 5,000 to 5,500 pounds. This capacity allows you to lift and work with large implements such as seeders, larger blades, and multi-bottom plows without issues.
If you use heavy or wide attachments, you can expect solid lifting power across a variety of field conditions. High lift capacity is important when you’re working with implements that carry loads or need reliable transportation around uneven terrain.
The electronic hitch adjusts to the weight consistently, maintaining safe and even operation. Actual performance can change with hydraulic health, weight distribution, and attachment design.
Draft / Position Control
The three-point hitch on this tractor comes with electronic draft and position control. Position control lets you set the exact height of your implement, giving you more precision when leveling or doing row work.
Draft control senses resistance as your implement moves through the ground and adjusts depth to keep traction steady. Electronic controls mean you get more consistency and accuracy compared to basic mechanical systems.
With draft and position control, you can reduce slippage, protect the soil, and prevent overloading the tractor. This feature is especially valuable if you switch tools often or need exact adjustment for different field conditions.
Top-Link Sensing (Yes/No)
The AGCO Allis 8745 is equipped with top-link sensing, which is used along with the electronic draft control. Top-link sensing detects any changes in angle or pressure at the upper link point of your hitch, sending this data to the control system.
With this system, the tractor adjusts depth and lift automatically to match ground conditions or changes in implement load. You get smoother operation during heavy tillage or when pulling through uneven, compacted soil.
Top-link sensing is mostly used for ground-engaging attachments that demand even and responsive draft management.
Axles & Load Limits
