Engine Specifications
The AGCO Allis 7630 tractor is powered by a reliable diesel engine known for its strong performance in heavy-duty fieldwork. Its core specifications, including configuration, power, fuel, and cooling system, set it up for capable service on medium to large farms.
Engine Make & Model
The AGCO Allis 7630 uses a 6-cylinder diesel engine. This engine is a direct injection, naturally aspirated unit designed to give consistent power in demanding tasks.
The engine was engineered to provide good fuel efficiency and straightforward maintenance. It is built for agricultural use, where reliability is essential during long workdays.
AGCO sourced this engine to deliver a balance between performance and durability. Service access points are accessible for daily checks and scheduled maintenance.
Fuel Type & Emissions Tier
Your 7630 tractor runs on conventional diesel fuel. Diesel is chosen for its energy density and efficiency, especially under continuous, heavy loads.
The AGCO Allis 7630 predates strict emissions standards found in modern tractors. It does not meet current Tier 4 emissions regulations.
Instead, it operates under older standards, so exhaust treatment systems like DEF or DPF are not required. Operators can expect straightforward fueling and few emissions-related maintenance requirements.
However, this also means it produces higher emissions compared to new models with advanced emissions controls.
Cylinders / Displacement
The engine features 6 cylinders, providing smooth power delivery and better balance at various RPMs. Having six cylinders makes the engine capable of sustaining high loads.
Engine displacement is 380.34 cubic inches (6.2 liters). This large displacement allows the tractor to develop strong low-end torque and hold speed under heavy loads.
The 6.2L capacity means you get both muscle and capacity for heavier equipment and longer operational periods. Fewer small parts also make it easier to service as needed.
Rated Horsepower (Gross & Net)
The AGCO Allis 7630 has a gross engine output of 122.2 horsepower (91.1 kW). The PTO (Power Take-Off) horsepower is rated at 115 hp.
PTO horsepower is what you use for running implements such as balers and mowers. Net engine horsepower figures are not always published, but you can expect it to be slightly lower than gross ratings due to losses in the driveline.
Peak Torque (Nm @ Rpm)
Torque is an important factor for a tractor. While official peak torque numbers (in Nm at specific RPMs) for the AGCO Allis 7630 are not widely published, tractors in this class offer high torque output at low to mid RPM ranges.
You can expect peak torque in the range of 400–500 Nm (approximately 295–370 lb-ft). The peak is usually achieved at a modest engine speed, providing the pulling power required for tillage or hauling tasks.
Thanks to its 6-cylinder, 6.2L engine, the 7630 maintains good torque under load, which is essential for field operations that need constant pulling force.
Compression Ratio
The precise compression ratio for the AGCO Allis 7630 engine is not often featured in summary listings, but diesel engines of this era and size typically have a compression ratio between 16:1 and 18:1.
This relatively high compression allows for efficient combustion of diesel fuel, helping both power output and fuel economy. Higher compression ratios are typical in agricultural diesel engines, supporting better cold starts and smoother running.
You should follow recommended maintenance and use quality diesel to maintain proper compression and engine health over time.
Cooling System & Capacity
The AGCO Allis 7630 uses an air-cooled diesel engine. This system relies on airflow around the engine to remove excess heat, rather than a liquid-based radiator found in most modern tractors.
The air-cooling design means fewer components compared to a liquid-cooled system—no radiators, water pumps, or coolant hoses. This translates into less frequent cooling system maintenance but requires that engine fins and shrouds remain clean.
The engine’s overall oil capacity is approximately 23.1 gallons (87.4 liters) for the hydraulic and cooling systems combined. Regular inspection and cleaning of air passages are important to prevent overheating during peak operation.

The AGCO Allis 7630 tractor features a robust power take-off system for running a variety of implements. You get flexibility with horsepower, PTO types, and speed settings for efficient performance.
Claimed PTO Horsepower
The AGCO Allis 7630 is rated for around 104 to 110 PTO horsepower, depending on the specific model year and testing method. This rating lets you operate most moderate-to-large implements, such as rotary mowers, balers, and tillers, effectively.
You should always check the actual PTO horsepower measured from the tractor’s output, since engine horsepower is usually higher. Losses occur due to mechanical transfer through the driveline.
Having about 104–110 hp at the PTO output means the tractor can handle most implements intended for tractors in the 120-engine-hp class. Different attachments have different requirements.
Always match the attachment’s minimum PTO horsepower needs with what the tractor provides to prevent overloading or poor performance.
PTO Type (Independent / Live / Economy)
Your AGCO Allis 7630 is equipped with an independent PTO system. This means you can engage or disengage the PTO using a switch or lever, even if the transmission is running or stopped.
You do not need to operate the clutch to use the PTO. This independent type is especially useful for work like baling or running mowers.
You can start and stop the implement smoothly without affecting the tractor’s movement. The system uses a hydraulic wet disc clutch for added durability and reduced maintenance.
Having an independent PTO saves you time during fieldwork and makes it safer when connecting or disconnecting various implements. It also allows you to maintain a steady implement speed even when changing tractor speeds.
PTO Speeds (540 / 1 000 Rpm)
The AGCO Allis 7630 provides both 540 and 1,000 rpm PTO speeds. This dual speed is selectable, often by changing a shaft or moving a lever, depending on which implement you are using.
The 540 rpm setting is most common for tools like smaller rotary mowers, post-hole diggers, and spreaders. The 1,000 rpm setting is used for larger implements such as heavy-duty balers, forage choppers, and many commercial tools that demand higher speeds.
The tractor’s PTO shaft is 1.375 inches in diameter, fitting most standard attachments. Using the right PTO speed helps prevent damage to implements and ensures good work quality.
Always check your implement’s required PTO speed before hooking up.

Transmission & Drivetrain
The AGCO Allis 7630 tractor uses a synchromesh transmission, paired with a multi-range gearing system, to deliver flexible performance for various field and transport tasks. Features like multi-wheel drive, a differential lock, and a sturdy clutch make this tractor well suited for demanding jobs where traction and control are important.
Transmission Type (Syncro, Powershift, CVT, HST)
The AGCO Allis 7630 comes equipped with a synchromesh transmission. This type allows you to shift gears smoothly with the help of synchronizers that match shaft speeds.
You do not have to bring the tractor to a complete stop to change gears, which makes fieldwork and road transport more efficient. The clutch system in the 7630 uses a hydraulic cerametallic disc that measures 350mm in diameter.
This disc is designed for durability and can handle the tractor’s higher power output. A hydraulic clutch gives you smooth engagement and helps reduce wear over time.
The synchromesh design means maintenance is straightforward and breakdowns are less likely compared to more complex transmissions like CVT or powershift.
Number Of Gears / Ranges
The tractor features a 24-speed transmission with 24 forward gears and 12 reverse gears. The ample number of gears gives you the flexibility to select the right speed and power for any job, whether it’s heavy fieldwork or lighter transport duties.
Gears are split into several mechanical ranges, usually High, Medium, and Low. These ranges, along with the number of gears, make it easier to keep the tractor working in its optimal power band.
Shifting between ranges is done mechanically, but the synchromesh system helps keep changes smooth. This gear setup lets you maintain efficient ground speed even under varying loads or changing field conditions.
You can match your speed more closely to the implement you’re using, reducing fuel waste and improving job quality.
Top Transport Speed
The AGCO Allis 7630 is designed for work in the field and for road transport between sites. The top transport speed is generally around 25-30 km/h (15-19 mph), depending on tires and local regulations.
Having a higher transport speed means you spend less time moving between fields. This is especially helpful if you manage multiple plots that are not next to each other.
Stable road handling at these speeds is important for safety and efficiency. At top speed, the transmission’s gearing keeps the engine within a safe RPM range, protecting both the motor and the transmission components from extra wear.
You should always check your operator’s manual and follow any guidelines for safe transport speeds to avoid accidents or damage.
Drive (2WD / 4WD / AWD)
The AGCO Allis 7630 is typically available with mechanical front-wheel drive (MFWD), often called 4WD. This drive system powers both the front and rear axles, giving you better traction in wet, muddy, or uneven ground conditions.
You can select and disengage front-wheel drive using a simple lever or switch in the cab. This allows you to maximize fuel efficiency when full traction isn’t needed.
4WD also improves brake performance and load handling, especially when pulling heavy implements or operating on slopes. Rear-wheel drive is still available for situations where turning radius and fuel efficiency are more important.
The MFWD system is built for durability, enabling steady operation in tough field conditions.
Differential-Lock & Final Drives
The AGCO Allis 7630 includes a differential-lock feature on the rear axle. You can engage this manually to ensure both rear wheels turn at the same speed.
This is especially useful when you need extra traction in mud or soft ground where one wheel might otherwise spin. The final drives transfer power from the axles to the wheels.
On the 7630, these are built to handle the tractor’s 122 horsepower and deliver long service life. The combination of strong final drives and a robust differential lock reduces wheel slip and helps protect your soil by minimizing uneven tire spins.
Routine maintenance of the differential-lock mechanism and final drives is important. Keeping these systems in good condition means less downtime and better overall performance in the field.

Steering & Brakes
The AGCO Allis 7630 uses a reliable steering and brake system built for tough field work. The design helps you handle the tractor safely while giving you good control, even with heavy loads or uneven ground.
Steering System (Hydrostatic / Power-Assisted / Mechanical)
You get hydrostatic power steering on the AGCO Allis 7630. This means the steering uses hydraulic power, making it much easier to turn the front wheels.
Even at low speeds or when holding a load, you won’t need much effort to steer. The system features a dedicated hydraulic pump for the steering circuit.
This helps prevent the steering from getting stiff, even if you are using other hydraulic functions at the same time. Power-assisted steering also reduces operator fatigue on long days in the field.
Hydrostatic systems tend to need less maintenance than mechanical linkages. If problems ever occur, most issues are with hydraulic fluid, hoses, or the steering cylinder.
Regular checks for leaks or low hydraulic oil keep your steering working smoothly.
Turning Radius (With Brakes)
The AGCO Allis 7630 has a tight turning radius for a four-wheel drive tractor. This helps when you’re working in small fields or need to maneuver around obstacles.
Using the individual brake pedals lets you make even tighter turns. Turning with brakes (brake-assisted turning) allows each rear wheel to slow down or stop independently.
Stepping on the left or right brake pedal makes the tractor pivot around that wheel. This is helpful for sharp corners, row crop work, or getting in and out of tight spots.
The typical turning radius for the 7630 is about 13-14 feet (4-4.3 meters), but using the brakes can make the turn even sharper. You can handle headlands and close quarters without backing up often.
Service Brakes (Wet Disc, Dry Drum, etc.)
Your AGCO Allis 7630 tractor uses hydraulic wet disc brakes for service braking. Wet disc brakes have metal discs running in oil, which improves cooling and extends the life of the brakes.
This type of brake is more effective in harsh or muddy conditions and provides smoother stops. The brakes are foot-operated and split for left/right control.
The design allows the brakes to be used individually or locked together, depending on your needs. Wet disc brakes also need less frequent adjustment compared to dry drum brakes.
You should still check brake fluid and watch for oil leaks. Proper care helps avoid brake fade and keeps stopping performance strong.
Parking Brake Type
The AGCO Allis 7630 is equipped with a mechanical parking brake. This system is separate from the main service brakes and is designed to keep the tractor securely stopped, even on slopes.
You engage the parking brake with a solid hand lever in the cab. When set, it holds the brake discs in position, preventing wheel movement.
Because it is mechanical, you do not have to rely on hydraulic pressure to keep the tractor parked. Regularly check the parking brake linkage for wear or adjustment needs.
Keeping it in good shape guards against unexpected rolling or movement when you leave the tractor parked.

ROPS / Cab Option
The AGCO Allis 7630 offers both cab and open station setups. Most models come standard with a cab featuring integrated Roll-Over Protective Structure (ROPS).
This means you are protected from rollovers, a critical safety feature, especially on uneven ground. If you prefer more visibility or simplicity, open station designs are available.
These lack the climate features of a cab but give you easier entry and exit. The cab design uses large glass panels for good visibility and a secure environment.
ROPS in both configurations meets modern farm safety standards. Doors on the cab are wide, letting you enter and exit without trouble.
The cab also keeps dust and debris out, making long days safer and more comfortable.
Climate Control (A/C, Heater, Filter)
Inside the cab, you have access to both air conditioning and heating. This combination allows you to work year-round in comfort, even during peak summer or in cold winter conditions.
The heater system is built into the main controls and pushes warm air evenly across the cab. The air conditioning helps cool the interior quickly on hot days.
Both are controlled by simple and reachable switches. A fresh air filter is included, blocking dust and pollen from entering the operator space.
This makes a noticeable difference in air quality, letting you work longer without discomfort or allergies acting up.
Seat & Suspension
You sit on a fully adjustable suspension seat designed to reduce fatigue over long workdays. The seat can be moved forward, back, and adjusted in height.
Suspension absorbs shocks from rough ground, protecting your back and legs from strain. Armrests are standard, and padding is thick and supportive.
The seat material is easy to clean and stands up to daily use. Controls for adjusting the seat are simple and placed within arm’s reach.
If you share the tractor with other operators, multiple adjustments make it easy to fit any body size. The seat’s vibrations and bumps are kept low by quality suspension, meaning you stay focused and comfortable throughout your shift.
Noise Level (dB A @ Operator Ear)
Noise inside the cab or operator station varies depending on setup. In the fully enclosed cab, noise levels are reduced thanks to insulation and sealed doors.
You can expect values around 80–85 dB A, typical for tractors of this size. In open station models, noise is higher.
Engine and implement sounds are more noticeable, which can increase fatigue during long hours. Using hearing protection is advised if you operate with the cab open for extended periods.
The sound system inside the cab is designed to let you hear radio or alerts without too much background engine noise. This balance helps you stay alert to both your machine and any external hazards.

Hydraulics
The AGCO Allis 7630 tractor uses an open-center hydraulic system built for reliability and straightforward operation. Understanding the specific capacity, pressure, and controls of this system is important when planning for different tasks and implements.
System Type (Open-Center / Closed-Center / PFC)
Your tractor features an open-center hydraulic system. Oil flows continually through the system and returns to the reservoir when not in use.
Open-center systems are common in this power range and are valued for their simplicity and ease of maintenance. This type of system means hydraulic functions operate sequentially rather than simultaneously at full demand.
While more basic than closed-center or pressure-flow compensated (PFC) systems, open-center offers dependable performance for most farm tasks. You should expect consistent operation when running one hydraulic function at a time.
Implement Pump Flow (L Min⁻¹)
The AGCO Allis 7630 hydraulic system delivers a main pump flow of approximately 23.1 gallons per minute (87.4 liters per minute) for implement operation. This pump capacity supports most implements, such as loaders, planters, and mowers.
If you use equipment that requires a high continuous flow, double-check the implement’s requirements to avoid slow cycle times. Adequate flow ensures quicker lifting, lowering, and cycling of implements.
For multi-function tasks that stretch system capacity, you may notice slower responses since the open-center flow is shared.
Steering Pump Flow (If Separate)
On the 7630, the hydraulic system uses a shared pump for both implement and steering functions, meaning there is no separate dedicated steering pump. Steering and hydraulic implement operations use flow from the same system.
While steering gets priority through a priority valve, simultaneous heavy use of both functions could lead to slight decreases in steering response during maximum hydraulic demand. For normal operation, you should notice smooth steering and consistent implement movement.
Awareness of total flow limits will help prevent steering lag in demanding situations.
Total Combined Flow
Because your implement and steering circuits are both fed by the same pump, the total combined hydraulic flow is 87.4 liters per minute (23.1 GPM). This total output covers all auxiliary hydraulic needs, including remote valves and steering.
When using several hydraulic features at once, pump output is divided, so total available flow can be stretched thin during peak demand. If performance drops while operating multiple functions, you can plan to prioritize the most important operations one at a time to maintain steady pressure and flow.
System Pressure (Bar / Psi)
The AGCO Allis 7630 hydraulic system operates at a maximum pressure of around 185 bar (approximately 2,700 psi). This pressure rating is standard for tractors of this size and ensures reliable lifting and implement control.
Pressure helps determine the lifting and breakout force available to your attachments. High system pressure is important for heavy tasks such as loader work or when running hydraulic cylinders on larger implements.
Regular maintenance of hoses and fittings is important to keep pressure performance at expected levels.
Remote Valves (Number & Type)
Your tractor is equipped with two or more standard remote hydraulic valves, commonly referred to as “remotes” or “SCVs” (Selective Control Valves). These outlets let you power a variety of hydraulic implements.
Valves are typically double-acting and allow you to control cylinders or hydraulic motors in both directions. Additional remotes may be installed depending on model options.
Control levers in the cab let you manage each valve independently. Check your implement connections and always use compatible fittings to prevent leaks or damage.

Three-Point Hitch (3PH)
The AGCO Allis 7630 features a rear-mounted three-point hitch that offers versatility for a wide range of agricultural tasks. Key aspects include the hitch category, lift capacity, control systems, and whether top-link sensing is provided.
| Feature | Details |
|---|---|
| Hitch Category | Category 2 |
| Lift Capacity @ Ball Ends | Approx. 6,000–7,000 lbs |
| Draft / Position Control | Standard: Position & Draft Control |
| Top-Link Sensing | No (Conventional setup) |
Hitch Category (1 / 1N / 2 / 3)
The AGCO Allis 7630 uses a Category 2 three-point hitch. This category is common for mid- to large-size tractors in the 100+ horsepower range.
Category 2 hitches have lift arm pin diameters of 1 inch and top link pins of 1 inch. This hitch type lets you easily attach a broad selection of implements and tools.
If you use heavy tillage equipment, mowers, or larger field implements, Category 2 is well-suited. You should make sure your implements match the hitch size to ensure safe, effective operation.
Lift Capacity @ Ball Ends
You can expect a lift capacity at the ball ends of about 6,000 to 7,000 pounds on the AGCO Allis 7630. This strong lifting power lets you handle heavy implements such as large plows, cultivators, and planters.
The lift arms run hydraulically, controlled from the operator’s station. You should always check the weight of your attachments and confirm they fall within the hitch’s rated limit.
For uneven terrain or heavy loads, lifting performance may vary. Proper ballast and careful operation help you make full use of the hitch’s strength.
Draft / Position Control
The AGCO Allis 7630 three-point hitch includes both position and draft control. Position control lets you set your implement height accurately.
This is useful for finishing, mowing, or planting, as it keeps tools at a set depth above the ground. Draft control is designed for soil-working tools like plows.
It senses the pull or drag and automatically raises or lowers the hitch to maintain a steady working depth. Using both systems together helps provide smoother field work.
You can switch systems using the tractor’s in-cab controls, fitting your needs for different types of jobs.
Top-Link Sensing (Yes/No)
The AGCO Allis 7630 does not include top-link sensing in its standard 3-point hitch system. Top-link sensing is more commonly found in newer or advanced tractors with electronic hitch control.
Instead, the 7630 uses a mechanical system based on the lower link arms for draft sensing. You do not get automatic top-link feedback for load adjustment.
If you require precise top-link sensing, you may need an aftermarket system or a tractor model with this feature. For most field applications, the lower-link sensing is sufficient.
Axles & Load Limits
You need to know the specific axle ratings and how the final-drive design affects performance. These details help you safely operate the AGCO Allis 7630 at its full potential and protect its critical components during heavy work.
| Specification | Value/Type | Importance |
|---|---|---|
| Maximum Front-Axle Load | ~3,600–4,500 kg* | Supports weight from front ballast/load |
| Maximum Rear-Axle Load | ~5,500–7,000 kg* | Handles majority of towed implement load |
| Final-Drive Type | Flange Rear Axle | Directly affects durability and use |
*Approximate typical range for this tractor class.
Maximum Front-Axle Load (Kg)
The front axle on the AGCO Allis 7630 supports the engine weight, fuel tank, and any front-mounted equipment or weights. It is essential to avoid exceeding the front-axle load limit to maintain steering ability and reduce wear.
Typical front-axle load limits for tractors of this size range from about 3,600 kg to 4,500 kg. You should check your operator’s manual or the data plate on the axle to confirm your model’s exact rating.
Staying within these limits is especially important if you use front loaders or heavy ballast. Not following the maximum front-axle load limit can cause premature axle or bearing failure.
It can also impact the stability of your tractor, increasing the risk of accidents.
Maximum Rear-Axle Load (Kg)
The rear axle on the 7630 bears most of the load during field work, especially when pulling equipment and carrying mounted implements. This axle must handle more weight than the front, especially when the three-point hitch and drawbar are in use.
Typical maximum rear-axle load ratings for row-crop tractors like the 7630 fall between 5,500 kg and 7,000 kg. Heavy loads beyond this can harm the axle, reduce traction, and damage rear tires.
Always make sure not to overload, particularly when transporting bales or heavy attachments. Properly distributing the load between the front and rear axles will help keep your tractor balanced.
Excessive load on the rear axle can lead to rear-end wear or even axle breakage.
Final-Drive Type
The AGCO Allis 7630 comes equipped with a flange-type rear axle. This design offers increased durability and a wider axle base compared to some other types.
Flange axles are often chosen for row-crop tractors because they offer good strength for mounting wide tires and handling heavy implements. The flange design also makes it easier to adjust the tread width to match crop rows or field conditions.
It supports the weight of large rear wheels and helps distribute force more evenly along the axle. Many users prefer this setup for its reliability in demanding field work.
