This setup allows for more precise fuel delivery and helps reduce waste, leading to better combustion and lower fuel consumption. AGCO DT225B engines comply with stringent emissions standards.

The engine typically meets at least Tier 3 (Stage IIIA) emissions requirements, restricting the levels of nitrogen oxides (NOx) and particulate matter (PM) it releases. Emissions control features might include exhaust gas recirculation or advanced aftertreatment systems.

Cylinders / Displacement

In the DT225B, the engine is an inline 6-cylinder design. This arrangement ensures smooth operation and balances power delivery across the RPM range.

The displacement stands at 8.4 liters, or 8,400 cubic centimeters. A larger displacement increases torque and helps the engine maintain speed under load, making it well-suited for demanding field applications.

Six cylinders allow for efficient air and fuel distribution, keeping vibrations down and prolonging engine life. Each cylinder works under high pressure, delivering power evenly.

Rated Horsepower (Gross & Net)

The AGCO DT225B is rated at 265 horsepower (197.6 kW) at the engine, according to manufacturer data. This is sometimes listed as “gross” horsepower, meaning it is measured at the flywheel before power is lost to other tractor systems.

PTO (Power Take-Off) horsepower, which measures usable power to attachments, is listed as 225 horsepower (167.8 kW) claimed but can reach up to 269.4 horsepower (200.9 kW) in some test conditions. The net horsepower rating is slightly lower than the gross, as it accounts for power drain from standard accessories.

Consistent power output is supported by electronic management and robust design. The tractor can handle high-draw operations like tillage and large hay tools.

Peak Torque (Nm @ Rpm)

Peak engine torque for the AGCO DT225B approaches or exceeds 1,150 Newton-meters (Nm). Some documentation lists figures closer to 1,200 Nm.

Maximum torque is typically delivered at lower RPM—often between 1,500 and 1,700 rpm. This lower-RPM torque curve allows you to perform heavy work with less fuel and reduces engine strain.

A flat torque curve means the engine maintains strong pulling power even when working at slower speeds or under heavier loads. A strong peak torque figure ensures better tractive effort, which is important for pulling implements or working in tough field conditions.

Compression Ratio

The engine’s compression ratio is specified at 16.7:1. This figure refers to how tightly the engine compresses the fuel-air mixture before ignition.

The DT225B comes equipped with the PowerMaxx CVT, a continuously variable transmission. This CVT design gives you seamless throttle-to-ground control.

There are no gear steps, so you can set any speed you want within its range. You do not need to shift between gears when changing speed or direction.

This helps when doing tasks that require steady speeds, like planting or spraying. The CVT system can optimize efficiency by letting the engine run at its most efficient speed for the job.

There is no traditional clutch needed for gear changes or direction reversal. The PowerControl lever allows you to change directions smoothly.

PowerControl X features may also be available on some models, giving you advanced shuttle and headland management options.

Number of Gears / Ranges

The CVT provides infinite speeds, both forward and reverse. This means there are no fixed gears or ranges like you would find on a traditional syncro or powershift transmission.

You have precise control over your ground speed. It allows you to choose the best speed for the work being done, such as slow speeds for planting or faster speeds for light tillage.

Changing direction is simple thanks to the PowerControl lever. You can shuttle between forward and reverse without stopping or using a foot clutch, making loader work and headland turns quicker.

Top Transport Speed

The maximum transport speed is around 31 mph (50 km/h), which is high for a tractor of this size. This lets you move quickly between fields or get to the road efficiently.

The advanced CVT transmission delivers smooth acceleration and deceleration. You do not feel the lags that sometimes happen with gear shift models.

Top speed depends on tire size and local regulations, but the system is designed with road travel in mind, including safe braking and stability.

Drive (2WD / 4WD / AWD)

The AGCO DT225B uses MFWD, which stands for Mechanical Front Wheel Drive. This system is also called 4WD.

All four wheels provide traction most of the time. MFWD gives you better performance on hills, in mud, or with heavy pull.

It helps keep you moving in tough ground conditions. You can switch MFWD on and off from the cab.

Use it only when needed to save fuel and reduce tire wear. The full-time 4WD locks front and rear axles together for demanding fieldwork.

Differential-Lock & Final Drives

The DT225B features a heavy-duty rear axle and final drives to handle the 265 hp output. The tractor is equipped with automatic and manual differential lock systems.

This means you can lock the rear wheels together to avoid slipping in tough spots. The diff lock can be engaged by a button in the cab, often working together with advanced electronics for automatic use when required.

MFWD models often include a front axle diff lock as well, increasing overall traction. The final drives are outboard planetary type, made for long-term durability and heavy loads.

Regular maintenance is important to ensure these components last and perform correctly.

You do not have to fight with the wheel in tight turns or rough terrain. The steering stays responsive even at low speeds or when the tractor is under a heavy load.

Hydraulic power steering reduces physical strain and improves accuracy, making it easier to control the tractor precisely in all situations. It also works well no matter the field conditions.

Turning Radius (With Brakes)

The DT225B has a tight turning radius for its size. When you use the brakes to help turn, also called “brake-assisted turning,” you can make sharper cornering movements.

This is useful for working in smaller fields or when you need to turn around quickly at the row ends. The large front wheels and the steering geometry are designed to get as close as possible to the ideal turning circle for a tractor this size.

You can rely on smooth, controlled turns with or without the aid of brakes, so you waste less time repositioning and more time working.

Service Brakes (Wet Disc, Dry Drum, etc.)

The service brakes on the DT225B are hydraulic wet disc brakes. Hydraulic pressure activates the brakes, and the wet disc design means the braking discs are cooled and lubricated by hydraulic oil.

This system provides strong, reliable stopping power, even when the tractor is under full load. Wet disc brakes last longer because the oil keeps the components cool and clean.

You notice less brake fade during repeated stops compared to dry drum brakes. This braking system also requires less maintenance and gives consistent performance in all weather conditions.

Parking Brake Type

The parking brake on the DT225B is typically a mechanical lever type. You set it by pulling a lever in the cab, which applies mechanical force to hold the brake discs in place.

This keeps the tractor from rolling when it’s parked on a slope or when you’re stopped for loading or unloading. The system is reliable and simple to operate.

Mechanical parking brakes are easy to engage and disengage without complex controls. You can trust this system to keep the tractor securely in place during long stops.

This cab design also includes high-visibility windows, ensuring you always have a clear field of view in all directions. The cab doors seal tightly for better pressurization.

This reduces dust exposure and helps keep out unwanted noise or fumes. Large entry steps, well-placed handholds, and wide doors make it easy to enter and exit the cab.

Advanced features like power-adjustable mirrors are available to help you see around larger implements or attachments. The cab is built to be spacious enough for you to move comfortably during operation.

Climate Control (A/C, Heater, Filter)

Your tractor’s cab is fitted standard with both air-conditioning and a heater. This allows you to manage the temperature during any season.

The automatic temperature control system keeps the air inside the cab at your set level, even as outside weather changes. Filters clean incoming air to remove dust and pollen, helping you breathe easier, especially during long days in the field.

Multi-stage filtration and circulation fans work together to keep the air fresh. If you need more, optional climate upgrades offer even more precise settings and stronger filtration.

Adjustable vents are placed throughout the cab. You can direct air to where it’s needed most, such as the feet, seat, or directly at the operator.

This attention to detail keeps you comfortable and alert.

Seat & Suspension

You benefit from an ergonomic seat design that can include optional heating and multiple adjustment points to fit your body size and shape. The seat uses air suspension, which reduces bumps and vibrations from uneven ground.

This helps lower fatigue and makes long hours in the tractor more comfortable. The cab is designed with a flat floor and good legroom.

Adjustable armrests and controls are placed within easy reach, so you don’t have to stretch or twist your body to operate the main functions. Power-adjustable mirrors are available to give you better views of equipment behind you.

If you need extra comfort, you can also choose automatic suspension settings that adjust to field conditions. This adaptive system further smooths your ride and keeps you stable while working.

Noise Level (dB A @ Operator Ear)

Noise control is a priority in the AGCO DT225B cab. Thick sound insulation in the cab roof, floor, and side panels significantly lowers the noise that reaches your ears.

While the manufacturer does not publish a specific dB(A) value, field reports and similar models suggest that it is very quiet—typically below 75 dB(A) at the operator’s ear. Pressurized cab doors and sealed windows help block outside noise from entering.

This lower sound level not only helps you communicate easily over a radio or phone but also reduces stress and fatigue during long shifts. You can also expect less vibration compared to open-station tractors.

The cab’s climate control and filtration system operates with minimal extra noise. This means you can run heating, air conditioning, or the fan without much noticeable sound increase inside the cab.

Hydraulics

The AGCO DT225B uses an advanced hydraulic system that supports large implements and heavy-duty field work. Its power and flexibility help you handle a wide range of farming tasks efficiently.

System Type (Open-Center / Closed-Center / PFC)

This tractor features a closed-center, pressure-and-flow-compensated (PFC) hydraulic system. This means that hydraulic pressure is maintained even when the system is not in use, which reduces lag and improves response times for hydraulic controls.

The PFC system can adjust flow and pressure based on demand, making it efficient and smooth during operation. You benefit from quick lifting and lowering of implements, with less engine load when hydraulic demand is low.

This system helps save fuel and reduces heat buildup. You get steady performance, especially when working with multiple hydraulic functions at once.

Implement Pump Flow (L Min⁻¹)

The implement pump on the AGCO DT225B delivers a high flow rate to meet the needs of large implements. It is designed to provide about 120 liters per minute (L/min), though actual numbers may vary slightly depending on model year and configuration.

This flow rate is able to handle large planters, sprayers, and other implements that require steady or high hydraulic demand. With this much flow, you can run several hydraulic functions at once without a decrease in performance.

Large implements requiring constant or high-flow hydraulics get the power they need. Even in demanding conditions, you don’t have to worry about flow shortages affecting your work.

Steering Pump Flow (If Separate)

The steering pump on the AGCO DT225B is separate from the main implement pump. Having a dedicated steering pump ensures that your steering remains easy and reliable, even when you are using heavy hydraulic implements.

The steering pump usually supplies around 40 liters per minute, which is enough for smooth and responsive steering at any speed. This separation means steering does not compete with other hydraulic needs, so you maintain control at all times.

Whether running the loader or multiple remotes, you don’t lose steering power. This setup is important for safety and ease of use in field operations.

Total Combined Flow

The total combined hydraulic flow for the AGCO DT225B adds the outputs of both the implement pump and the steering pump. Normally, the combined rate reaches about 160 liters per minute.

This value gives you a sense of the tractor’s total hydraulic capacity and is important when running equipment with high simultaneous hydraulic demand. A higher combined flow lets you operate complex implements with multiple functions, like folding, lifting, and powering motors at the same time.

This makes your tractor more versatile and capable in modern farming settings, especially when using tools that need multiple hydraulic outlets at once.

System Pressure (Bar / Psi)

The AGCO DT225B hydraulic system operates at a system pressure around 290 bar, or about 4,200 psi. This high pressure supports lifting, tilting, and operating heavy implements with speed and control.

High system pressure also improves response and makes implement operations more precise. You will notice faster cycle times for loaders or other moving parts and consistent power even under heavy loads.

This hydraulic pressure allows for work with larger attachments and better performance across many jobs.

Remote Valves (Number & Type)

Your AGCO DT225B often comes equipped with four to six rear remote valves as standard. The number can be increased if you need more for specialized tasks.

The remotes are electro-hydraulic, allowing you to control each valve easily from the cab with switches or levers. Electro-hydraulic remotes support flow control and timing adjustments, making them flexible for different implements.

The layout makes it simple to run several hydraulic tools at once. You can add more remotes or adjust settings as your needs change.

Lift Capacity @ Ball Ends

The rear three-point hitch on the DT225B has a lift capacity rated at 26,460 pounds (12,002 kg) at the ball ends. This high lift capacity means you can raise and carry some of the heaviest implements available for row-crop tractors.

Whether handling a heavy disc, a sizable planter, or a multi-row cultivator, the DT225B’s three-point hitch gives you confidence that your equipment will be handled safely and efficiently.

The strong hydraulic system paired with the hitch ensures both lifting power and durability in demanding field conditions.

Draft / Position Control

The tractor includes both draft and position control systems standard on the rear hitch. With position control, you can set and maintain a precise implement height, which is helpful for tasks like seeding or mowing.

Draft control automatically adjusts the position of your implement based on how much resistance it encounters in the ground. This means your plow or tool stays at a steady depth, even if the soil gets harder or softer.

You’ll find this feature especially useful when tilling or plowing uneven ground, as it helps you keep a consistent working depth. Both controls are easily accessible from the operator’s seat, so you can make changes as soon as conditions in the field change.

Top-Link Sensing (Yes/No)

Top-link sensing is not standard on every DT225B configuration. Some setups may have it as an optional feature.

If installed, top-link sensing further increases the accuracy of draft control by monitoring the force on your implement’s top link. This system helps you maintain a consistent implement depth, even as soil conditions change in different parts of your field.

Without top-link sensing, you’ll still have reliable draft and position control. Adding top-link sensing is recommended if you plan to do a lot of plowing or similar heavy draft work.

Check your specific DT225B to see if this option is installed or available from your dealer.

Fuel-Tank Capacity

Your AGCO DT225B comes with a large diesel fuel tank built for long working hours. The main fuel tank holds up to 155.9 gallons (590.1 liters) of diesel.

This high capacity means you can operate in the field for many hours before needing to refill. The fuel tank is located on the left side of the tractor.

The size helps reduce downtime by limiting the frequency of stops. For best results, always use clean, high-quality diesel that meets manufacturer standards.

You should check your fuel levels at the start of every work period. Using contaminated or low-grade fuel can cause problems in the fuel system.

DEF-Tank Capacity (If Applicable)

The AGCO DT225B uses a Diesel Exhaust Fluid (DEF) system to meet emissions requirements. The DEF tank has a capacity of about 7.9 gallons (29.9 liters).

You’ll find the DEF tank next to the main diesel tank for easy access. DEF is a special fluid used to reduce harmful emissions and must be kept separate from diesel fuel.

The tractor has warning systems to tell you when the DEF level is low. If the tank runs empty, the tractor’s power may be reduced until you refill it.

Always use the correct grade of DEF to avoid damage to the system. Store DEF at moderate temperatures to keep it effective.

Engine Oil Capacity

Proper engine oil levels are crucial for reducing engine wear in your DT225B. The engine holds about 30–35 quarts (28–33 liters) of oil, though exact capacity can vary by engine configuration.

Always check by the dipstick or in the owner’s manual for exact numbers. Use a high-quality diesel engine oil as recommended by AGCO.

Check oil before operation, especially during long work stretches. Change oil and filters based on the hour-meter or maintenance chart, whichever comes first.

Running with low or old oil can lead to serious engine damage. Make sure to use the correct oil type and quantity for best results.

Hydraulic/Transmission Oil Capacity

The hydraulic and transmission system in the DT225B is combined, sharing a common reservoir. The system typically requires around 55 gallons (208 liters), but this can vary by model year or specific hydraulic options.

Hydraulic fluid is checked at a rear fill port and should be kept between the minimum and maximum marks. Change intervals depend on how hard and often you use your tractor.

Always keep hydraulic filters clean and check for leaks around hoses and fittings. The correct fluid level ensures your tractor’s transmission, hydraulics, and implements run smoothly and reliably.

Using the wrong fluid type or running low can cause serious performance issues.

Electrical System

AGCO DT225B tractors use a modern electrical system designed to support heavy-duty work and advanced features. This section covers ground configuration, charging performance, battery specifications, and key points about electrical reliability.

Ground Type (Negative / Positive)

You will find that the AGCO DT225B tractor uses a negative ground electrical system. Negative ground is commonly seen in modern agricultural equipment because it enhances compatibility with various electronic components and attachments.

A negative ground system means the tractor’s chassis is connected to the negative terminal of the battery. This setup helps prevent electrical issues, such as voltage drops and inconsistent grounding.

It also makes troubleshooting and maintaining your tractor’s electrical system easier, ensuring reliability during operation. Older tractors sometimes used positive ground, but negative ground systems like the DT225B are standard.

This allows you to use common diagnostic tools and makes it simpler to connect accessories without special adapters or modifications.

Alternator / Charging System

Your AGCO DT225B is equipped with a heavy-duty alternator. The alternator is responsible for maintaining battery charge and supplying power to electronic systems while the engine is running.

This alternator uses an internal voltage regulator to deliver a steady output. It supplies consistent voltage for lighting, electronic controls, and cab features such as the air conditioning and ISOBUS compatibility.

High electrical loads, especially when using additional work lights or electronic accessories, put extra demand on the alternator. The AGCO DT225B alternator is designed to handle these loads efficiently.

Charging Output (Amps)

The DT225B’s alternator is rated for a charging output of about 200 amps. This high output supports not just starting and essential electrical systems, but also modern tractor features like electronic engine management and multiple auxiliary power outlets.

A robust charging output is crucial when running attachments that require electrical power, such as GPS systems or telematics equipment. With this capacity, you can operate additional lighting and equipment without concern for battery drain during long workdays.

If you plan to use high-draw accessories, it’s important to stay within the rated charging output.

Battery Voltage

The AGCO DT225B tractor uses a 12-volt electrical system. This is the standard for most agricultural tractors, making it easy to source replacement batteries and related electrical components.

A 12-volt system is compatible with most tractor accessories and attachments, including lighting, controls, and communication equipment. This voltage level also ensures the starter motor receives enough power for consistent and rapid engine starting, even in colder weather.

When performing maintenance, always check that any replacement parts and accessories are rated for a 12-volt system.

Battery CCA Rating

Your DT225B requires a battery with a high Cold Cranking Amps (CCA) rating. The recommended CCA for this model is around 950 to 1,000 amps.

This ensures the battery can deliver enough starting power, even in low temperatures. A higher CCA rating also provides better reliability for the engine’s electronic systems and allows for consistent starts after periods of inactivity.

Using a battery with insufficient CCA can lead to hard starting and may affect the performance of onboard systems during critical operations. When replacing the battery, check the label or manufacturer’s guidelines for the correct CCA rating.

Total Cost Of Ownership Metrics

Understanding your total cost to own the AGCO DT225B tractor helps with budgeting and long-term planning. Maintenance schedules, yearly expenses, depreciation rates, and fuel usage all impact what you spend over the lifetime of this 265 hp machine.

Recommended Service Intervals

You should follow the manufacturer’s recommended maintenance schedule to keep the AGCO DT225B running well. Regular engine oil and filter changes are advised every 250 hours of use.

The transmission fluid and filter should be replaced roughly every 500 hours. Hydraulic filters and fluids also need attention at 500-hour intervals.

Routine checks include inspecting belts, hoses, and air filters. Greasing joints and inspecting tire pressure should be done more often, often every 50 hours.

The cooling system and batteries need inspection at least twice a year. Adhering to these intervals can prevent performance loss and unexpected repairs.

Estimated Annual Maintenance Cost

Annual maintenance costs depend on how many hours the tractor is worked and the cost of labor in your area. For an AGCO DT225B used for about 800–1,000 hours per year, you should expect yearly maintenance to range from $2,500 to $4,000.
