| Shaft Size | 1-3/8″, 6-spline (common standard) |
Claimed PTO Horsepower
The AGCO ST60A has an engine rated at 46 horsepower. The power delivered to the PTO is slightly less due to normal drivetrain losses, which is typical with all tractors.
For most tasks, the PTO power will be around 38 to 40 horsepower at the shaft. This is enough for mid-sized implements such as rotary cutters, small balers, tillers, and some sprayers.
Having this power level makes it suitable for hay work, mowing, or heavy-duty yard maintenance. You should always pair implements with the PTO rating to avoid overloading. This helps both the tractor and the attachment run efficiently and last longer.
PTO Type (Independent / Live / Economy)
Your AGCO ST60A features an independent PTO system. This means you can engage or disengage the PTO separately from the tractor’s main transmission or travel clutch.
With an independent PTO, you get more control, especially when you need to start or stop implements while the tractor keeps moving. This is helpful for baling, mowing, or using rear attachments where constant motion is needed, but you may need to stop PTO power quickly.
Some tractors have live or economy PTOs, but the independent design is typically more user-friendly and safe.
PTO Speeds (540 / 1 000 Rpm)
The tractor offers two PTO speed options: 540 rpm and 1,000 rpm. You select the speed that matches your attachment’s needs.
- 540 rpm is the standard speed for most common implements like mowers, tillers, and spreaders.
- 1,000 rpm is for larger, high-powered tools like some balers or chippers.
Selecting the correct PTO speed is important. Attaching an implement rated for 540 rpm to the 1,000 rpm shaft can damage the implement and cause safety hazards.
Always check your equipment’s requirements and use the matching PTO speed for safe and efficient function.
Transmission & Drivetrain

Transmission Type (Syncro, Powershift, CVT, HST)
This tractor features a PowerShuttle transmission with QuadraShift. The PowerShuttle lets you shift between forward and reverse without using the clutch, making it easier when you need to change directions often.
This setup is especially helpful during loader work or when maneuvering in tight places. The system uses a manual synchro gearbox as its base for the four gears in each range.
The operator uses the shuttle lever to quickly reverse direction. This design provides a combination of durability and ease of use.
Number of Gears / Ranges
You get 12 forward and 12 reverse gears in the AGCO ST60A. There are three ranges—low, medium, and high—with four gears in each range.
You can shift between gears within each range without having to stop or use the clutch. This setup allows you to match the speed and power to your task.
Whether you are tilling, mowing, or hauling, you can pick the right gear and range for efficient work.
Top Transport Speed
The AGCO ST60A can reach a top transport speed of about 17 to 20 mph (27–32 km/h), depending on tire size and load. This lets you move quickly between fields or around your property.
On paved or solid surfaces, you can travel at highway speeds for a compact utility tractor, reducing your overall travel time.
When moving heavy loads, the power and gear selection help you keep steady speed and control.
Drive (2WD / 4WD / AWD)
The standard setup for the ST60A is 4WD (four-wheel drive). This system powers all wheels at once for improved traction and stability, especially on uneven or slippery ground.
You get better pulling power and control in mud, snow, or loose dirt. Being a 4WD model means you can also use heavier implements and work on steeper or rougher land.
The drivetrain handles the extra strain put on it during hard work.
Differential-Lock & Final Drives
The tractor comes with a rear differential lock. You can engage it when one wheel starts slipping to force both rear wheels to turn together.
This provides maximum traction when the ground is wet, soft, or uneven. You can easily activate the lock from the operator’s seat as needed.
The final drives are heavy-duty planetary reduction units. These reduce stress on the axle and improve overall durability, even when putting down high torque or carrying heavy loads.
The sturdy final drives ensure long service life with less maintenance during heavy use.
Steering & Brakes
The AGCO ST60A tractor uses advanced steering and robust brakes to improve safety and handling. Both systems play a direct role in how well you can operate your tractor in fields and on roads, especially during sharp turns or when stopping suddenly.
Steering System (Hydrostatic / Power-Assisted / Mechanical)
The AGCO ST60A comes equipped with a hydrostatic power steering system. This setup uses hydraulic pressure to make steering smooth and light, even under heavy load or at low speeds.
You can expect easy maneuvering, which reduces driver fatigue during long hours of operation. The steering wheel remains responsive, making quick corrections possible if you hit bumps or uneven ground.
Hydrostatic steering is especially helpful when using front-end loaders or other attachments, as it prevents the wheel from feeling stiff or unresponsive. Maintenance is minimal due to fewer moving mechanical parts compared to older mechanical systems.
Turning Radius (With Brakes)
The turning radius of the ST60A is tight for a tractor of its size, making it easier to navigate small fields or areas with obstacles. When you use the brakes to assist the turn, you can make even sharper turns.
Using brake-assisted turning, you apply the brake on the inside rear wheel, which effectively pivots the tractor around that wheel. This is useful during headland turns or when making quick adjustments in confined spaces.
The clean, sharp steering response lets you position implements more precisely.
Tight steering is also important for reducing soil compaction, as fewer wide turns are needed.
Service Brakes (Wet Disc, Dry Drum, etc.)
The AGCO ST60A uses wet disc brakes as its main service braking system. Wet disc brakes are placed inside a sealed housing filled with oil, which keeps them cool and helps prevent wear.
This design ensures reliable stopping power and consistent brake feel, even after many hours of use. Wet disc brakes are known for their durability and need less frequent service than dry drum brakes.
They’re also less affected by mud, water, or dust, making your stops safer in different field conditions. There’s reduced fading during heavy braking or when operating on slopes.
Parking Brake Type
The parking brake on the ST60A is integrated within the wet disc brake system. This design adds safety, as the parking brake uses the same reliable wet discs rather than a separate, less robust mechanism.
To engage the parking brake, you pull a lever in the operator’s area. The system then locks the wheels in place, preventing movement even on sloped or uneven ground.
Because the brake is inside a sealed housing, it’s protected from water and dirt, ensuring it holds well over time.
| Feature/System | ST60A Details | Benefits |
|---|---|---|
| Steering System | Hydrostatic power steering | Easy handling, low fatigue |
| Turning Radius | Tight, enhanced with brake-assisted turning | Maneuvers well in tight spaces |
| Service Brakes | Wet disc brakes (oil-cooled, sealed) | Durable, safe, low maintenance |
| Parking Brake | Integrated wet disc system, hand lever activated | Secure hold, reliable in field |
Cab & Operator Station
You get a basic but practical operator environment on the AGCO ST60A. There are options for ROPS or cab, climate features, and comfort elements such as a suspension seat.
| Feature | Details | Notes |
|---|---|---|
| ROPS / Cab Option | Open ROPS, Aftermarket Yukon Cab Available | Cab is bolt-on, not ROPS-certified |
| Climate Control | Optional heater, possible basic cab A/C | Varies by cab installation |
| Seat & Suspension | Adjustable mechanical suspension seat | Adjustable positions, ergonomic seat |
| Noise Level (dB A @ Operator Ear) | Not specified, generally moderate for horsepower | Lower in cab than open ROPS |
ROPS / Cab Option
The AGCO ST60A comes standard with an open ROPS (Roll-Over Protective Structure) for safety. This helps protect you in the event of a rollover and meets basic safety requirements for agricultural use.
The ROPS is sturdy and remains in place if you add aftermarket cabs. Yukon offers a bolt-together cab kit that fits directly to the ST60A.
This cab is not ROPS-certified, meaning the existing factory ROPS still provides rollover protection, while the cab only offers weather protection and extra comfort. The Yukon cab matches the appearance of factory cabs, offering doors, windows, and structural coverage from the elements.
Keep in mind the Yukon-style cab is an add-on and relies on the original ROPS for safety.
Climate Control (A/C, Heater, Filter)
If you install the optional cab, you can add climate control features such as a heater, defroster, and sometimes basic air conditioning units. Heating is the most common, with simple controls and vents to keep the interior comfortable during cold weather.
Air conditioning is sometimes possible for the ST60A if you use aftermarket retrofit kits, but not all cab kits have it standard. Filtration may involve basic dust filters to help keep the cab cleaner but is less advanced than larger tractors.
There is no automatic climate control or separate filter system; what you get depends on your cab selection. With the open ROPS, there are no climate features except open-air ventilation.
The cab option improves year-round usability by blocking wind, rain, and dust.
Seat & Suspension
You get an adjustable mechanical suspension seat on the AGCO ST60A. The seat is wide and padded for comfort, reducing fatigue during long hours of operation.
Height, angle, and fore-aft seating position can be easily changed to suit your preferences. The seat is designed to absorb some vibration from rough terrain, which helps minimize the impact of bumpy fields.
There are no advanced air-ride or heated seat options, but the design is functional for most jobs. Armrests are basic but help support your arms during operation.
Ergonomics are improved with clear access to all controls, levers, and pedals within easy reach of the operator station.
Noise Level (dB A @ Operator Ear)
There is no published official noise level for the AGCO ST60A at the operator station. For a 46-hp compact utility tractor, noise levels can range from 80 to 90 dBA with open ROPS.
Most of the sound comes from the diesel engine and driveline. If you use the bolt-on Yukon cab, sound levels drop slightly thanks to the doors and glass enclosing the operator area.
The weather-sealed cab cuts wind noise, but you may still hear some engine sound. For long operations, wearing hearing protection is recommended in open ROPS setups.
The cab improves comfort but does not fully isolate you from noise like larger, premium tractor cabs might.
Hydraulics
The AGCO ST60A features a hydraulic system designed for reliable performance during daily use and demanding jobs. Key areas include the system design, pump output, available remotes, and pressure capacity.
System Type (Open-Center / Closed-Center / PFC)
You get an open-center hydraulic system with the AGCO ST60A tractor. This system is common on compact and utility tractors in this power range.
An open-center system uses a single pump to send hydraulic oil through the control valves. When you are not using the hydraulic levers, oil flows freely back to the reservoir.
This is a simple design, which means fewer components and easier maintenance. You do not have the advanced features of closed-center or pressure-and-flow-compensated (PFC) systems, but the open-center layout is enough for most basic implements.
It’s dependable for jobs like lifting, tipping trailers, or running small front loaders. Mechanics can diagnose problems and make repairs more easily because it’s a straightforward system.
Implement Pump Flow (L Min⁻¹)
The AGCO ST60A tractor provides an implement pump flow of approximately 48.4 liters per minute (L/min). This flow rate allows you to operate standard hydraulic attachments, including rear implements, loaders, or lift arms.
The output is enough for tasks such as operating hydraulic cylinders or powering auxiliary equipment attached via the rear or mid-mount outlets. With this capacity, you can expect fast response times when lifting or leveling loads.
Most implements made for compact tractors work within these limits. Still, you should always check your specific attachment’s requirements before use.
Higher flow rates can handle more demanding equipment, but for typical farming, property maintenance, or light construction, 48.4 L/min is suitable and delivers steady performance.
Steering Pump Flow (If Separate)
On the AGCO ST60A, steering flow is handled by the main hydraulic pump and is not separate from the implement pump.
The single-pump design means both functions—steering and implement hydraulics—share the available oil flow.
While you steer or operate a loader at the same time, you might notice a small reduction in speed if both are heavily loaded.
Even during simultaneous use, you can steer with little extra effort, but if you are using multiple high-demand hydraulic tools at once, you may feel a modest lag.
This setup keeps things simple.
It also means less to service under the hood, which can lower long-term maintenance costs.
Total Combined Flow
The AGCO ST60A offers a total combined flow from its hydraulic pump of about 48.4 L/min (or 12.8 gallons per minute).
This total flow covers all hydraulic functions—both implements and steering.
It determines how quickly cylinders extend or retract and how fast attachments can move.
In practice, you get enough capacity for using typical implements found on a 46 hp tractor.
You may notice slower operation if you try to run multiple high-flow tools at the same time.
The pump is robust and designed to supply even, consistent oil pressure for daily work.
System Pressure (Bar / Psi)
System pressure on the AGCO ST60A’s hydraulics reaches about 170 bar (2,465 psi).
This pressure allows the tractor to lift heavy rear implements or use loader attachments without struggle.
The higher the pressure, the greater the force available for hydraulic cylinders to raise, lower, or adjust tools.
The pressure level is matched to the tractor’s frame and lift system.
This prevents overloading and protects both your implements and the hydraulic system itself.
For heavy work like ground-engaging implements or lifting large bales, this pressure specification gives you enough muscle for the job.
Remote Valves (Number & Type)
The AGCO ST60A typically offers two rear hydraulic remotes as standard, both of type Category I/II 3-point hitch controls.
These remotes allow you to connect implements that need hydraulic power to lift, angle, or move.
The valves are usually double-acting, meaning you can both extend and retract the attached cylinder directly from the cab controls.
You may choose to add more remotes if your work requires several hydraulic tools at once.
Modular kits are available for additional remotes, allowing flexibility for different implements or future needs.
Each remote is color-coded and uses standard quick-connect couplers.
This makes it simple to connect or remove hoses as tools are switched between jobs.

Three-Point Hitch (3PH)
The AGCO ST60A tractor features a three-point hitch (3PH) system designed for strength, flexibility, and compatibility with a variety of implements.
The hitch system affects which attachments you can use, the weight you can lift, and how accurately you can control your implements in different field conditions.
| Feature | Specification | Details |
|---|---|---|
| Hitch Category | Category 1 / 2 | Fits standard implements and provides versatility |
| Lift Capacity (Ends) | 3,748 lbs (1,700 kg) | Measured at the ball ends for direct implement attachment |
| Lift Capacity (24″) | 3,307 lbs (1,500 kg) | Measured 24” behind ball center for most implements |
| Draft/Position Control | Yes | Offers precise implement height and depth adjustments |
| Top-Link Sensing | No | Does not include top-link sensing for automatic adjustment |
Hitch Category (1 / 1N / 2 / 3)
Your AGCO ST60A comes standard with a three-point hitch that uses Category 1 or Category 2 connections.
Category 1 is the most common for compact and mid-size tractors.
Pins for Category 1 are 7/8 inch in diameter, and the arm spacing is about 26 inches.
Category 2 uses 1-1/8 inch pins and a 32-inch arm spacing.
This design means you can use implements meant for either category, giving you more flexibility when choosing plows, mowers, or tillers.
Make sure to check the implement you want to use for the correct size.
Some models may offer adapters so you can switch between categories as needed.
You do not get support for Category 3 implements, which are typically reserved for larger, higher-horsepower tractors.
Lift Capacity @ Ball Ends
The rear three-point hitch lift capacity is a critical factor for any tractor.
On the AGCO ST60A, this capacity is 3,748 pounds (1,700 kg) at the ball ends.
At 24 inches behind the ball ends, where most implements connect, the lifting capacity is 3,307 lbs (1,500 kg).
That number represents the tractor’s ability to raise heavy implements such as rotary cutters, box blades, or planters with stable control.
When lifting heavier attachments, keep in mind that the tractor’s front end can get light.
Adding proper front ballast helps balance your tractor to keep it stable while operating heavy rear implements.
Draft / Position Control
You get both draft control and position control on the AGCO ST60A’s 3PH.
Draft control automatically adjusts the hitch height based on soil resistance, which is helpful for ground-engaging tools like plows.
Position control lets you set and maintain the exact height of your implement.
This feature helps when you want to keep an attachment—such as a mower or blade—at a specific level for consistent results.
Using both controls, you can fine-tune your field work for different tasks and soil types.
Top-Link Sensing (Yes/No)
The AGCO ST60A three-point hitch does not include top-link sensing.
Top-link sensing is a feature found on some larger tractors that helps the hitch system adjust based on the angle or pressure sensed at the upper link of the hitch.
Without top-link sensing, all automatic adjustability comes from draft control sensors located elsewhere.
For most users and most tasks at this horsepower level, top-link sensing is not missed, but you should be aware of its absence if you move up to larger, more advanced tractors later.
Axles & Load Limits
The AGCO ST60A’s axles and load limits play a key role in its durability and performance.
Each axle has a specific weight it can support, which helps prevent damage and improves safety when moving heavy equipment or carrying attachments.
Maximum Front-Axle Load (Kg)
The front axle on the AGCO ST60A is designed for stable steering and support, especially when using loaders or front-mounted attachments.
Knowing the load limit for the front axle helps you avoid overloading, which can cause steering problems or axle damage.
The typical maximum load for the front axle is around 1,500 kg (3,306 lbs).
However, this value may vary with specific tire choices, front weights, or added implements.
Overloading the front axle can lead to early wear or even axle failure.
It’s important to pay attention to guidelines from the manual and to balance loads properly when attaching heavy implements.
Key considerations
- Avoid carrying more than the rated weight on the front axle.
- Adding front weights or a loader increases axle stress.
- Keep front tires correctly inflated for safe operation.
Maximum Rear-Axle Load (Kg)
The rear axle manages much of the tractor’s total load, especially during fieldwork, towing, or when using rear attachments.
This axle also supports the 3-point hitch, which has a lift capacity of up to 1,700 kg at the ends and 1,500 kg at 24 inches behind the lift points.
The rear axle’s maximum load is usually close to 3,700 kg (about 8,157 lbs), depending on configuration and tire size.
Overloading the rear axle can affect traction, risk damage, and reduce stability.
For best results, always distribute weight evenly and avoid exceeding the published limits for both implements and towed loads.
Tips for safe rear-axle use:
- Secure implements properly.
- Check axle and tire condition before heavy use.
- Add ballast if needed for better balance.
Final-Drive Type
The AGCO ST60A uses a mechanical final drive system, common on utility tractors in the 46 hp class.
This system delivers engine power to the wheels through a combination of gears and shafts, increasing torque and protecting the driveline components.
The final drive is reliable for regular field tasks and loader work.
It is designed for both 2WD and 4WD versions of the ST60A.
