This setup helps you avoid fatigue and improves safety, especially when operating attachments or navigating uneven terrain.
A mechanical differential lock is included on the rear axle, which provides extra traction when needed.
Turning Radius (With Brakes)
The turning radius is a critical measure for users who need to navigate in small fields or around obstacles.
On the AGCO GT45, the turning radius is tight due to efficient steering geometry and the option to use brakes to “assist” the turn.
With brake-assisted steering, you can apply one brake to help pivot the tractor even more sharply.
This technique allows for a smaller turning circle, making it easier to work in compact spaces.
Brakes on the rear wheels can be used independently, making sharp turns possible and handling chores in corners or beside fences much smoother for you.
Service Brakes (Wet Disc, Dry Drum, Etc.)
The AGCO GT45 uses wet disc brakes for its main service braking system.
Wet disc brakes are housed inside a sealed compartment filled with oil. This design keeps them cool, quiet, and less likely to wear or get damaged by dirt and moisture.
Wet disc brakes are very reliable, even if you need to stop suddenly or use the brakes repeatedly over a short period.
This is better than dry drum brakes, which can overheat and lose their effectiveness if used too much.
Wet disc brakes are also easier to maintain and last longer, providing consistent stopping power all season long.
Parking Brake Type
The parking brake on the AGCO GT45 is mechanical.
You activate it by engaging a lever, which locks the brakes in place.
Unlike automatic or hydraulic parking brakes, mechanical systems are simple and offer direct engagement, which reduces the risk of accidental roll-away if left parked on an incline.
This type of brake is easy to check and adjust if needed.
Its straightforward design also means fewer parts that might fail, giving you more peace of mind when parking the tractor on slopes or while hooking up implements.

Climate Control (A/C, Heater, Filter)
The optional cab can come equipped with a full climate control system.
Air conditioning lets you work comfortably in the summer.
A heater keeps you warm as temperatures drop, making the tractor usable in cold months.
An air filter helps keep dust and allergens out, which is useful for those working in dry, dusty fields.
These controls are typically straightforward and located for easy access from the operator’s seat.
If you plan to use your tractor in different seasons, having climate control is a practical upgrade.
Open station (ROPS-only) models do not have climate control, but some operators use seat covers or fans for limited relief from the heat.
Seat & Suspension
The seat in the AGCO GT45 is designed for support and adjustability.
You can usually adjust seat height and position, letting you find a comfortable spot during use.
The basic suspension provides shock absorption over bumpy terrain.
For longer jobs, seat padding is substantial enough to minimize fatigue.
On models with an enclosed cab, the seat often has armrests for added support.
While it is not a luxury seat, the design focuses on functional comfort for daily tasks.
The flat-floor design gives you more legroom and makes it easy to get in and out of the operator station.
High-wear materials extend seat life, even in tough conditions.
Noise Level (dB A @ Operator Ear)
The AGCO GT45 aims to control noise at the operator’s ear, but specific decibel (dB) values can depend on your model’s setup—open station or cab.
Enclosed cabs have better sound insulation and can be noticeably quieter, lowering daily noise exposure compared to open ROPS units.
With ROPS only, you will experience more engine and external noise, especially under heavy load.
While engine design and cab insulation help, regular ear protection may still be wise if you’re running for long periods.
The focus is on engineering out high-frequency engine sounds and providing noise reduction through insulation and material choice.
Hydraulics
Hydraulic functions on the AGCO GT45 tractor are important for running implements, steering, and lifting heavy loads.
The specifications define your tractor’s ability to handle different tasks and determine which tools and attachments it can support.
System Type (Open-Center / Closed-Center / PFC)
Your AGCO GT45 uses an open-center hydraulic system.
In open-center systems, hydraulic fluid flows continuously through the valves when not in use, returning to the reservoir.
Open-center systems are simple and reliable. This type supports most farm tasks and general loader work well.
There is no pressure unless a function is running, reducing heat build-up.
This system provides steady, predictable hydraulic power for implements and attachments.
Automatic flow adjustment is not available as in advanced systems like closed-center or PFC (Pressure and Flow Compensated) setups.
You get basic, robust operation that is easy to maintain and fix.
Implement Pump Flow (L Min⁻¹)
The implement pump on the AGCO GT45 provides a flow rate of 14 gallons per minute (gpm), which equals 53 liters per minute (L/min).
This flow rate affects how fast you can operate hydraulic tools, loaders, and lifts.
A flow of 53 L/min is suitable for most medium-duty implements.
It allows efficient operation of front-end loaders, mowers, and some hydraulic-driven attachments.
If you use tools that need higher flow, this tractor may have some limits.
Most agricultural jobs fit within this range, so you can expect good performance for typical fieldwork, hay handling, or loader tasks.
Steering Pump Flow (If Separate)
On the AGCO GT45, the pump that provides flow for implements also feeds the steering. These tractors do not have a separate steering pump.
The same open-center system manages both functions. Combined steering and implement hydraulic systems are common for mid-sized tractors.
This means steering always has access to operating flow. Heavy loader or implement use could affect steering response under max load.
Rapid loader or three-point hitch use could momentarily draw flow away from steering. Proper maintenance reduces impact, but awareness of this is important in demanding work.
Total Combined Flow
The total hydraulic flow rate on the AGCO GT45 is 22.7 gpm (85.9 L/min). This total combines the flow available to both the steering and implement circuits.
Having 85.9 L/min lets you run multiple hydraulic operations at once, including lifting, steering, and powering attachments. This total output boosts productivity, especially during loader work when steering and lifting happen together.
If you run several functions at once, you may notice some reduction in speed due to flow sharing.
System Pressure (Bar / Psi)
The AGCO GT45’s open-center hydraulic system operates at pressures high enough for farming tasks but does not reach the levels of industrial tractors. The specific system pressure is not listed in all sources, but typical tractors in this class operate around 180–210 bar (2,600–3,000 psi).
This level of pressure is enough to lift heavy implements, operate loaders, and run common hydraulic tools on the farm. Always use hoses, couplers, and attachments that match this pressure range for safety and best performance.
Remote Valves (Number & Type)
Your AGCO GT45 comes equipped with at least one or two rear hydraulic remotes as standard. These are typically double-acting valves that allow you to extend and retract hydraulic cylinders for implements like plows or mowers.
Some models may offer up to three remotes, depending on the configuration and region. The standard type is simple lever-controlled, not electro-hydraulic.
The number and type of remote valves impact how many implements you can run at once. They allow you to connect tools that need hydraulic power for operation or movement.
| Feature | Specification / Details |
|---|---|
| System Type | Open-center |
| Implement Pump Flow | 14 gpm (53 L/min) |
| Steering Pump Flow | Combined with implement pump (not separate) |
| Total Combined Flow | 22.7 gpm (85.9 L/min) |
| System Pressure | Estimated 180–210 bar (2,600–3,000 psi) |
| Remote Valves | 1–2 standard, lever-operated (double-acting), up to 3 on some models |
List of Key Points:
- Open-center design: simple, robust, steady flow
- 14 gpm (53 L/min) for implements
- Steering shares hydraulic flow with implements
- Total system output: 22.7 gpm (85.9 L/min)

| Draft/Position Control | Position and draft control available |
| Top-Link Sensing | No |
Hitch Category (1 / 1N / 2 / 3)
You get a Category II three-point hitch on the AGCO GT45. This is important because Category II hitches are common on mid-sized and utility tractors.
They are stronger than Category I and support larger, heavier implements like plows and mowers with more working width. The hitch uses pins with a 1-inch diameter and supports attachments that fall within Category II specifications.
You need to make sure any implement’s hitch pins match the tractor’s lower arm spacing and diameter. For smaller implements, you can sometimes use adapter bushings, but it’s best to fit tools designed for Category II.
Category II hitches are not interchangeable with Category I or III without adapters or conversion kits. Always check your implement’s hitch details before connection.
- Category Type: II
- Lower Link Pin Diameter: 1 inch
- Width Between Arms: 32 inches (approx.)
Lift Capacity @ Ball Ends
Lift capacity measures how much the rear lift can handle at the ends of the lift arms, close to where you connect attachments. On the AGCO GT45, the rear lift is rated for about 3,858 pounds (1,750 kg) at the ball ends.
This allows you to use a wide range of heavier implements, which is suitable for tougher field work like tilling or hauling. The actual weight you can lift depends on the implement’s center of gravity and how far it extends behind the tractor.
Make sure you stay within the lift capacity to avoid overloading the hydraulics or risking unsafe operation. Checking your attachment’s weight with operator and fluids included helps ensure safe use.
Key points:
- Maximum Lift at Ball Ends: ~3,858 lbs (1,750 kg)
- Works for implements like: Box blades, rotary cutters, medium-duty plows
Draft / Position Control
Draft and position control help you operate your three-point hitch with more precision. The AGCO GT45 has both position and draft control available from the operator’s seat.
Draft control adjusts the depth of ground-engaging tools automatically, depending on soil resistance. This keeps implements like plows at a steady working depth.
Position control lets you set the height of the hitch for transport or work zones. You can raise or lower implements to a specific height, then lock it in place until you need a change.
Both systems use simple levers or controls near the seat.
Top-Link Sensing (Yes/No)
The AGCO GT45 does not offer top-link sensing on the three-point hitch. Top-link sensing is mostly found on larger or advanced tractors and is used to measure forces on the top link for even finer draft control.
Without top-link sensing, draft adjustments are based only on the lower two hitch arms. For most farm tasks, this is reliable and straightforward.
When using implements that require very precise draft control, you may notice small differences.

| Final Drive Type | Two/ four-wheel drive, fixed arms | Durable, supports both drive configurations |
Maximum Front-Axle Load (Kg)
The AGCO GT45 is built to handle both two-wheel and four-wheel drive configurations. While the search results do not specify an exact maximum front axle load, the front axle is engineered for heavy-duty work.
With a loader attached, you can expect the front axle to manage up to about 3,000 lbs (1,360 kg), which matches the loader’s full lift capacity at the pin. This design supports loader work, field implements, and maneuvering on uneven ground.
You should always avoid overloading the front axle, especially when using front-end attachments. Too much weight causes premature wear and can affect steering.
Maximum Rear-Axle Load (Kg)
The rear of the AGCO GT45 is designed for lifting and carrying significant weight. The rear lift capacity at 24 inches (610 mm) is 3,520 lbs (1,596 kg).
This number indicates how much the rear axle can safely handle when using implements such as plows, mowers, and other attachments. Overloading can damage the hydraulic system and axle bearings.
If you are using heavy 3-point hitch implements, always check the weight first. Correctly balancing loads between the front and rear axles improves traction and overall tractor stability during operation.
Final-Drive Type
The AGCO GT45 features a durable final-drive system suited for both two-wheel drive (2WD) and four-wheel drive (4WD) versions. The rear arms are fixed, which adds extra strength for heavy lifting and consistent performance.
A robust final-drive means you can work in tougher field conditions with less concern about axle failures. This system efficiently transfers power from the engine to the wheels and PTO, supporting the 52 hp engine and various heavy tasks.
