| PTO Type | Independent |
| PTO Speeds | 540 rpm, 1,000 rpm |
Claimed PTO Horsepower
The AGCO Allis 5660 offers a claimed PTO horsepower of 56.9 hp (42.4 kW). This rating lets you know how much power is available to drive attached implements like rotary cutters, balers, or tillers.
The PTO horsepower is measured at the power take-off shaft, not just the engine. This distinction is important, because the PTO transfers actual usable power to your equipment.
The value of 56.9 hp means you can operate most medium-sized implements without difficulty. If you need to run more demanding equipment, knowing your tractor’s PTO rating helps prevent overloading.
PTO Type (Independent / Live / Economy)
The 5660 is equipped with an independent PTO. With this system, you control the PTO shaft operation separately from the transmission and ground speed.
Engaging or disengaging the PTO does not require depressing the clutch or stopping the tractor. An independent PTO gives you flexibility.
For example, if you need to slow down or stop for an obstacle, the implement keeps running. This is especially useful when working with equipment like mowers or balers, since stopping the PTO can leave unfinished spots or jam the machine.
Having an independent PTO also makes connecting or disconnecting implements easier and safer. You can keep the tractor stopped while operating the PTO.
PTO Speeds (540 / 1 000 Rpm)
The AGCO Allis 5660 comes with both 540 rpm and 1,000 rpm PTO speeds. This dual-speed setup means you can match the PTO speed to the needs of a wider range of implements.
Most small and medium implements work at 540 rpm, including many mowers and small balers. Large or higher-capacity implements often require 1,000 rpm to operate efficiently.
Switching between speeds usually involves changing the PTO shaft or selecting a lever, depending on your tractor’s configuration. This versatility allows you to use the same tractor for different jobs.
Transmission & Drivetrain
The AGCO Allis 5660 uses a mechanical transmission and a sturdy drivetrain system to transfer its 63 hp engine power to the ground. It is designed for reliable shifting, efficient field work, and solid traction control across different farm environments.
Transmission Type (Syncro, Powershift, CVT, HST)
You will find a synchromesh (syncro) transmission on the AGCO Allis 5660. This system allows you to shift gears with less grinding compared to older gear designs.
Gears mesh together smoothly while moving, which reduces wear and makes operation easier for long days in the cab. Syncro transmissions are popular in mid-size tractors like the 5660 because they balance simplicity and function.
You still need to use the clutch to change between gears, but the process feels smoother than with a sliding-gear box. This transmission type is built for durability and ease of repair if problems occur.
The AGCO Allis 5660 does not use a powershift, CVT, or hydrostatic (HST) transmission. If you prefer hands-on, mechanical gear control, this syncro design is fitting.
Number Of Gears / Ranges
The transmission on the Allis 5660 is built with versatility in mind. It typically features 8 forward gears and 2 reverse gears.
These gears are arranged across multiple ranges to give you flexibility for both fieldwork and transport. You can choose the right gear for every job, from slow speeds for tillage to faster speeds for travel between fields.
The gear lever is mounted in a position that is easy to reach. This setup ensures you have good control over speed and power.
The gear ratios are designed to help you use the engine’s power efficiently.
Top Transport Speed
The top transport speed of the 5660 is generally around 18 to 20 miles per hour (about 29 to 32 kilometers per hour). This allows you to move the tractor between job sites quickly and safely on roads or farm lanes.
You get enough speed for short trips without sacrificing stability or control. The brakes and steering are matched to the transport speed for safety.
This is fast enough for most farm needs but not suited for highway travel.
Drive (2WD / 4WD / AWD)
You can get the AGCO Allis 5660 in either standard 2-wheel drive (2WD) or mechanical front wheel drive (MFWD), which is Allis’s version of 4WD. The MFWD model gives extra traction in tough or slippery conditions by powering both front and rear axles.
When you use MFWD, it improves pulling power and reduces slippage, especially when working in wet fields or with large implements. The 2WD model is lighter and has a tighter turning radius, making it good for flat fields, dry ground, or loader work.
The 4WD (MFWD) is preferred when operating in hilly or muddy areas, hauling heavier loads, or performing deep tillage.
Differential-Lock & Final Drives
This tractor comes with a mechanical differential lock. You can manually engage it by pressing a foot pedal or lever.
The differential lock ensures both wheels on an axle turn together, letting you keep traction when one wheel starts to slip. For heavy-duty work or when traction is critical—such as when pulling out of muddy ruts—the differential lock becomes essential.
Final drives on the 5660 are composed of heavy-duty and reliable outboard planetary gear sets. These final drives multiply torque and deliver it directly to the wheels.
This ensures strong, steady pulling power and reduces stress on the axles and transmission.

| Turning Radius (With Brakes) | Tight turning with brake-assisted steering | Easier maneuvering in tight spaces |
| Service Brakes | Hydraulic Wet Disc | Reliable stopping power, low wear |
| Parking Brake Type | Mechanical Hand Lever | Secure hold on slopes and during stops |
Steering System (Hydrostatic / Power-Assisted / Mechanical)
You get hydrostatic power steering with the AGCO Allis 5660. This system uses hydraulic power to make steering much easier, even at low speeds or when you are carrying heavy loads.
You don’t have to use much force to turn the wheel, which reduces fatigue during long hours in the field. The hydrostatic system responds smoothly and quickly, so you have accurate control.
In bumpy or uneven conditions, the power-assisted setup helps you maintain your line and control the tractor with less effort. This type of steering is standard on both two-wheel and four-wheel drive models.
If you are used to mechanical steering, you will notice the difference right away. Power steering is not just a comfort feature; it makes a big impact on safety and precision.
Turning Radius (With Brakes)
The 5660 is designed with a tight turning radius. By using brake-assisted steering, you can turn more sharply than with the steering wheel alone.
This is useful for headland turns, working around obstacles, or lining up precisely for passes in row crops. You can press the left or right brake pedal to further reduce your turning circle.
The brakes act on the inner wheels, which helps pivot the tractor in place. Tight turns are possible, even with implements attached.
While maneuverability depends on conditions and tire setup, brake-assisted turns on the AGCO Allis 5660 give you good control and flexibility. This capability is especially important if you work in areas where space is limited or need to turn often.
Service Brakes (Wet Disc, Dry Drum, etc.)
The AGCO Allis 5660 uses hydraulic wet disc brakes. These brakes are immersed in oil, which reduces wear and heat buildup.
Wet disc brakes provide consistent and strong stopping power, even after long hours or in wet and muddy conditions. Hydraulic actuation means you can modulate braking force smoothly.
The brakes are designed to continue functioning well with heavy loads or when going downhill. They also last longer compared to dry drum brakes because the oil keeps them lubricated and less prone to overheating.
Wet disc brakes are low-maintenance, which saves you time and money over the life of the tractor. You also get reliable braking in all weather.
Parking Brake Type
The parking brake on the AGCO Allis 5660 is mechanical and uses a hand lever. To engage it, you pull up the lever, which locks the brakes in place and keeps the tractor from moving.
This setup is easy to use and check visually. The parking brake holds the tractor securely, even on slight grades or when parked with heavy implements attached.
It acts on the main service brakes, which gives you confidence that the machine will stay put when you stop. Mechanical hand lever parking brakes are known for their reliability.
There are few moving parts and little risk of hydraulic leaks. You can depend on the brake to hold whenever you park the tractor.
Cab & Operator Station
Comfort, safety, and ease of use are important when you operate the AGCO Allis 5660. The tractor’s operator station combines protection, climate management, seating, and sound reduction to create a usable space.

ROPS / Cab Option
Your AGCO Allis 5660 comes standard with a Roll-Over Protective Structure (ROPS). This structure protects you by preventing serious injury if the tractor tips over.
The ROPS is mounted securely and meets safety regulations for its class. Some versions of this tractor offer an enclosed cab as an option.
The full cab keeps out dust, wind, and bad weather, which can be a big benefit if you work in changing conditions. Controls for windows and doors are simple and within reach.
A cab adds weight to the machine but increases comfort and safety. Visibility is preserved with large windows, which help you monitor your surroundings and attachments easily.
Entry and exit are straightforward, with wide doors and sturdy steps equipped for added safety.
Climate Control (A/C, Heater, Filter)
If you choose the enclosed cab, you gain access to climate control features that provide comfort in all seasons. The cab can include an air conditioning unit for hot weather, delivering cool air directly into the operator area.
The heater system ensures warmth during cold months. Both systems are controlled from the main dashboard.
Filtration prevents dust and debris from entering the cab, which keeps the air cleaner and helps if you have allergies. Air vents are adjustable, so you can direct airflow where it is needed most.
The climate controls are simple to use and easy to reach from your seat. Operators working in extreme climates will notice the benefits of these systems.
Even after long hours, you can expect a consistent temperature and fewer distractions from the outside environment.
Seat & Suspension

A suspension system in the seat helps absorb shock from rough terrain. You feel less jolting during long days.
Padding is firm but comfortable to reduce fatigue. Armrests may be available, and controls are within reach for quick changes in seating position.
Fabric is typically durable and resists wear from daily use. You can quickly slide or tilt the seat to match your needs.
Visibility from the seat is wide, giving you a clear view of your work area and controls.
Noise Level (dB A @ Operator Ear)
Noise inside the AGCO Allis 5660 depends on whether you use a cab or just the ROPS. With only ROPS, you will notice engine and drivetrain sounds reach moderate to high levels, especially at full power.
Prolonged exposure may cause fatigue if hearing protection is not used. Cabs provide sound insulation that lowers the decibel level at your ear.
While not completely silent, you will notice a significant drop in engine, transmission, and implement noise inside an enclosed cab. This makes it easier to communicate through a radio or phone.
Typical sound levels are in the range of 80-90 dB(A) at the ear in open stations. The cab can reduce this by several decibels.
For best results, it is recommended to use the cab with closed windows when operating for long hours or in noisy environments.
Hydraulics
The AGCO Allis 5660 is equipped with a practical and robust hydraulic system. You get important details about the type, flow rate, system pressure, and remote valve options, which affect how you use implements and operate attachments.
System Type (Open-Center / Closed-Center / PFC)
The AGCO Allis 5660 uses an open-center hydraulic system. In an open-center design, hydraulic fluid flows constantly through the system while the tractor is running.
Pressure is only built up when you activate a control valve for an implement. This type of setup is commonly found in many utility tractors.
Open-center systems are easier to maintain and repair. They work well for most farm implements and loaders that do not need continuous high pressure.
You won’t find advanced features like pressure-flow compensation (PFC), but open-center systems are reliable. This system type is a good fit for tasks such as lifting, tipping, or steering, as long as they are not all used at once at their maximum flow.
Implement Pump Flow (L Min⁻¹)
The 5660’s hydraulic pump delivers a flow rate of 45.0 liters per minute (L/min), which is about 11.9 gallons per minute (gpm). This flow rate refers to the oil available for the implement circuits.
It determines how quickly cylinders on loaders, rear attachments, or other hydraulic implements can move. A 45.0 L/min flow is enough for medium to heavy loader work and common field implements such as mowers, plows, and tedders.
If you run equipment that needs a high flow, such as modern balers or advanced hydraulic tools, you should check the requirements.
Steering Pump Flow (If Separate)
On the AGCO Allis 5660, the steering and implement hydraulics usually share the same pump and oil supply. This means there isn’t a dedicated, separate pump just for the power steering.
Both the loader and the steering system draw from the same hydraulic flow. If you use several hydraulic functions at once, like steering while operating a front loader, you may notice a slight drop in steering response.
This is typical of shared-pump, open-center systems. You may feel small changes in speed or resistance when multiple hydraulic demands are happening together.
Total Combined Flow
Because the implement circuits and steering use the same pump on the AGCO Allis 5660, the total combined hydraulic flow is 45.0 L/min. When only one function is used, you get the full flow.
If both implements and steering compete for oil, the available flow is split between them. You should plan your operation around this shared capacity.
System Pressure (Bar / Psi)
The hydraulic system on the 5660 operates at a standard maximum pressure of around 180 bar (2,600 psi). This working pressure affects how much force the hydraulics can apply to implements and loader arms.
You benefit from reliable lifting power for typical agricultural tools and attachments. For example, a loader will lift heavy bales or manage dirt and feed without struggling, as long as weight stays within recommended ranges.
Hydraulic cylinders and hoses should always be checked for leaks or wear to ensure full system pressure is safely maintained.
Remote Valves (Number & Type)
The AGCO Allis 5660 usually features two remote hydraulic valves at the rear. These valves are standard dual spool types, allowing you to connect and control two separate hydraulic implements at once.
You can use these remotes for equipment such as loaders, rear blades, bale grabs, or other attachments needing one or two double-acting cylinders. The levers in the cab let you move each implement function independently.
Both remotes use standard quick-connect couplers, making implement hookup straightforward. If you need more remotes for advanced equipment, you would need additional aftermarket valves.
Hydraulic System Summary Table

Three-Point Hitch (3PH)
The AGCO Allis 5660 comes with a reliable three-point hitch system designed for field work, tillage, and a variety of implements. Its components and functions help you attach, control, and manage a wide range of equipment for efficient farming.
Hitch Category (1 / 1N / 2 / 3)
Your AGCO Allis 5660 is equipped with a Category 2 three-point hitch. This hitch size is standard for tractors within this horsepower range and allows you to use many common implements, such as plows, mowers, and cultivators designed for Category 2.
With a larger pin size and heavy-duty build, it offers added strength for heavier attachments. Category 2 uses 1-1/8 inch (lift arm) and 7/8 inch (top link) pins.
Implements built for this category connect securely and can withstand the demands of more intensive farming tasks. If you plan on using older or smaller equipment designed for Category 1, you may need conversion bushings.
For most modern medium tractors, Category 2 provides wide compatibility and strength. Knowing the category helps you make the right choices when purchasing attachments.
Lift Capacity @ Ball Ends
The lift capacity at the ball ends indicates how much weight your hitch can safely raise. On the AGCO Allis 5660, the three-point hitch typically has a lift capacity of around 3,200 to 3,500 pounds at the ball ends.
This is strong enough for heavy implements like large mowers, heavy plows, or specialized tillage tools without risk of overloading the system. Lift capacity numbers are important to match your equipment’s weight.
Try to stay well within this rating for improved longevity and performance. If an attachment is too heavy, it can put too much strain on the hydraulics and castings.
Make sure to factor in the weight of both the implement and any load it may carry. For best results, check your owner’s manual for exact limits and avoid exceeding them in demanding conditions.
Draft / Position Control
You have both draft and position control available with the 5660’s three-point hitch. Position control lets you set the hitch at a constant height, ideal for operations where uniform depth is key, like mowing or light tillage.
Draft control automatically adjusts the hitch in response to changes in soil resistance. When plowing or cultivating, this function helps keep the implement at a consistent working depth.
If soil conditions get tough, draft control raises the implement slightly to maintain traction and prevent wheel slip. Using draft control correctly minimizes manual adjustments and protects equipment from sudden shocks.
Top-Link Sensing (Yes/No)
The AGCO Allis 5660 does not come with top-link sensing as a built-in feature. Top-link sensing is found mostly on larger or more advanced tractors.
It allows the hydraulic system to react based on the force felt through the top link, giving even more precise automatic depth control. Without top-link sensing, your draft control works by detecting forces through the lower links.
For most jobs, this is effective. If you require top-link sensing, some aftermarket kits and retrofits may be available, but it’s not standard on this model.
For general use, the lower-link sensing system offers dependable performance for most traditional farm tasks.
| Feature | Specification / Details |
|---|---|
| Hitch Category | Category 2 (1-1/8″ lift arm pins, 7/8″ top link pins) |
| Lift Capacity @ Ball Ends | 3,200–3,500 lbs |

Maximum Front-Axle Load (Kg)
The front axle on the AGCO Allis 5660 is built to handle both the weight of the tractor and additional loads like front loaders or ballast weights. You can usually expect a maximum front-axle load of around 2,200 kg on this type of tractor.
This allows you to safely use heavy front-mounted implements. If you are driving on uneven ground or carrying a loader bucket full of material, try not to exceed this weight.
Going over the limit can cause premature wear on axle bearings and steering components. Always check local and manufacturer requirements for exact numbers based on your setup.
Using a loader or adding front weights means you need to pay close attention to the axle’s load capacity. This protects the axle and ensures your tractor remains stable.
Maximum Rear-Axle Load (Kg)
The rear axle handles much of the tractor’s total working load. For the AGCO Allis 5660, the maximum rear-axle load is typically around 3,500 kg.
This capacity supports heavy implements like plows, mowers, or trailers attached to the three-point hitch or the drawbar. When using heavy attachments, it’s important to distribute weight evenly across the rear tires.
Overloading the rear axle can lead to tire damage, axle breakage, and unsafe operating conditions, especially when operating on slopes or during transport. If you use ballast or wheel weights, add their weight into your total rear-axle load.
Check for signs of stress such as tire bulging or axle noise. Operating within the rated limit keeps your tractor performing reliably.
Final-Drive Type
The AGCO Allis 5660 uses an inboard planetary final-drive system. This type of drive multiplies torque and spreads forces over a greater area, creating a robust and durable connection between your engine and wheels.
Planetary final-drives are known for withstanding high loads and rough field conditions. Their inboard design means the main gears are protected inside the axle housing, reducing exposure to mud, debris, and other hazards.
For maintenance, these drives require regular oil level checks and inspection for wear or leaks. If you use your tractor for heavy tillage or on tough terrain, the planetary design provides consistent performance and helps avoid costly breakdowns.
Tires & Track Options
Choosing the right tires can affect how well your AGCO Allis 5660 works in fields and on roads. Both the type and size of tires matter for traction, stability, and soil protection.
There are specific standard tire sizes for front and rear, as well as options for upgrades if your work needs something different.
Standard Front Tire Size (Ag / Turf / Industrial)
The standard front tire for the AGCO Allis 5660 in agricultural use is usually a 7.50-16. This size provides a balance between steering accuracy and support for front-end loads.
If you use the 5660 in row crops or general farming, this ag tire offers good grip and moderate ground pressure. For operators who work on lawns or sports fields, turf tires are sometimes available from third-party suppliers.
Turf tires have a wider footprint and less aggressive tread. This allows for less marking on delicate surfaces.
However, the AGCO Allis 5660 does not have a widely advertised turf tire option from the factory. Industrial (R4) front tires are rarely fitted to this series, but adaptation is possible where improved puncture resistance or road handling is needed.
Most will find the ag (R1) tire best for typical fieldwork.
Standard Rear Tire Size
The standard rear tire for this model is 14.9R28. This radial agricultural tire gives the tractor good flotation and traction for plowing, planting, and other heavy tasks.
The 14.9 width spreads the tractor’s weight, reducing soil compaction. Other rear sizes may be available depending on country and dealer offerings.
Some owners upgrade to larger 16.9R28 tires for more ground contact or switch to bias-ply designs. Radial tires remain the most popular for this series because of their flex and ability to maintain grip in varying field conditions.
A correct rear tire maintains the correct ground speed for the power and transmission, making jobs like spraying and seeding more accurate.
Optional Duals / Tracks / Flotation Kits
AGCO did not offer factory-installed dual wheels, tracks, or flotation kits for the 5660. However, some owners add aftermarket dual rear wheels to improve stability, traction, and flotation in wet or loose soils.
Duals require proper spacers and wheel alignment, especially when working on hillsides or with heavy implements. Flotation tires or kits, which are even wider than standard, may be available from tire specialists.
These are useful in soft ground or when minimizing ruts is a priority. There are no known direct track conversion kits for the 5660, and retrofits would require significant modifications.

It offers flexibility for row spacing and operation through narrow gates or paths. Adjustable rear axle widths allow you to modify the tread setting for your specific crop or field requirements.
At its narrowest, you can pass through tighter field rows and avoid damaging crops. A width in this range strikes a balance between stability and crop clearance.
It gives you enough support to handle moderate side slopes safely, without being too wide for standard fieldwork. If your tasks require wider or narrower tracks, the tractor supports adjustments to the rear wheel positions.
Make these changes as needed based on your planting or cultivation methods.
Height To ROPS / Cab
The AGCO Allis 5660 reaches a height of 88.5 inches (224 cm) to the top of the Roll-Over Protective Structure (ROPS) or cab. This measurement is important for moving through doors, under tree branches, or into low sheds.
For many farm buildings, a height just under 7.5 feet allows convenient access. When you add optional equipment, such as beacons or antennas, factor in extra space above the cab.
If your barn or garage has a low entryway, measure before parking the tractor inside. The sturdy ROPS or cab frame is fixed and provides crucial protection.
Consider the extra height if you mount anything additional on top. The height also affects the operator’s view.
A higher platform usually gives you better forward visibility and a safer working environment. Make clearances a priority before moving the tractor into any enclosed or sheltered spaces.
Ground Clearance
Typical ground clearance for the AGCO Allis 5660 is approximately 16.5 to 18 inches, although actual clearance depends on tire size and tread settings. This height matters if you need to avoid damaging crops or work in uneven fields.
Higher ground clearance helps when working on rough, rocky, or muddy terrain. It lets you pass over tall stubble, debris, and small obstacles without risk of getting stuck.
If you operate in areas with frequent issues like ruts or rocks, this clearance reduces downtime and lowers the risk of undercarriage damage. This specification also benefits certain specialized tasks, such as cultivating high-row crops.
Check your configuration to confirm the precise measurement. Using larger or specialized tires can increase clearance, while lower-profile tires may reduce it.
Shipping Weight
The shipping weight of the AGCO Allis 5660 is 6,020 pounds (2,730 kg). This figure is the base weight of the tractor without fluids like fuel, oil, and coolant, and without optional equipment or attachments.
Knowing the shipping weight is important if you plan to transport the tractor by truck or trailer. Ensure your hauling equipment is rated for this load, considering road limits and tie-down requirements.
