Engine Specifications
The AGCO LT90 tractor is built with a strong diesel engine designed to deliver consistent power and high reliability. Key features include a Cummins engine, solid horsepower output, air-to-air cooling, and a robust compression ratio.
Engine Make & Model
You will find that the AGCO LT90 uses a Cummins B-series diesel engine. This engine is well known for its durable construction and dependability in agricultural applications.
The exact model can be identified as the Cummins 6BTA5.9. This is a six-cylinder engine that has seen wide use across tractors, combines, and other equipment for its ease of maintenance.
Cummins engines are common in this horsepower range due to their parts availability and proven track record. If you service or maintain equipment, you will appreciate the ability to source parts and technical information for the 6BTA5.9 model.
The engine features direct injection technology, which promotes more efficient fuel combustion and simpler cold starts. You can expect straightforward service intervals and familiar layout if you have worked with other Cummins diesel platforms.
Fuel Type & Emissions Tier
The engine requires diesel fuel. Diesel offers higher energy content per liter than gasoline and is standard for agricultural tractors in this range.
The AGCO LT90 tractor comes from a time before the latest emissions rules. You can expect it to meet Tier 2 emissions standards, which were common for tractors produced in the early to mid-2000s.
There is no DEF (diesel exhaust fluid) or exhaust after-treatment in this model. This can simplify operation and reduce extra maintenance tasks.
If your operation needs to minimize emissions, consider that Tier 2 engines do not include the latest particulate filters or SCR systems. These engines are valued for their simple, mechanical fuel systems and proven reliability.
Cylinders / Displacement
The engine in your LT90 has 6 cylinders arranged in a straight line (inline-six). This layout improves balance and smooth running at different engine speeds.
Displacement is 5.9 liters, or 359 cubic inches. Cleanly engineered six-cylinder diesels like this provide plenty of torque without high engine speeds.
The bore and stroke measure approximately 102 mm x 120 mm. This long stroke contributes to high torque output at low rpm, which is ideal for pulling heavy implements.
You will notice smoother performance and fewer vibrations compared to four-cylinder engines. The inline-six also promotes easier service access along each side of the engine.
Rated Horsepower (Gross & Net)
The AGCO LT90 engine offers a gross rated horsepower of 110 hp (82.0 kW) at 2200 rpm.
The PTO (power take-off) horsepower is listed as 85 hp (63.4 kW), which reflects the usable power delivered to implements and attachments. Testing has shown that the PTO can reach up to 87.7 hp under certain conditions.
Gross horsepower describes the raw output of the engine, while net horsepower factors in power lost to auxiliary systems (like alternators or fans). In field use, you will mostly focus on PTO or tested horsepower, as this tells you how much power is available for work.
This level of engine output makes the LT90 suitable for a wide range of tillage equipment, mowing, and haymaking tools.
Peak Torque (Nm @ rpm)
Peak torque is a critical spec for tractor performance. The AGCO LT90’s engine generates a maximum torque of about 436 Nm (322 lb-ft) at approximately 1251 rpm.
High torque at low rpm means you can work through tough soil or hilly terrain without frequent downshifting. The torque curve of the Cummins 6BTA5.9 remains flat over a wide rpm band, so you get steady pulling power.
This high torque supports demanding jobs such as plowing, baling, and loader work. Utility tractor operators will appreciate how the LT90 handles heavy loads with less engine strain.
If you need to maintain a steady speed up slopes or through thick grass, the high torque will help the tractor stay responsive and productive.
Compression Ratio
The compression ratio on the LT90’s Cummins diesel is 17.5:1.
A high compression ratio helps with efficient combustion and better fuel economy. It also supports reliable cold starting, which is important in variable climates.
With diesel engines, higher compression promotes more complete burning of the fuel. The 17.5:1 ratio found here is standard for non-turbocharged and turbocharged agricultural diesels from this period.
You can expect good thermal efficiency, meaning the engine uses more of the fuel’s energy for actual work and less is lost as heat.
Cooling System & Capacity
The LT90 uses a liquid-cooled system with a large front-mounted radiator. The cooling system relies on a belt-driven water pump to move coolant through the engine block, cylinder head, and radiator.
Capacity of the cooling system is approximately 16 liters (4.2 US gallons) of coolant.
An air-to-air intercooler is included to help further reduce intake air temperatures and improve power output during heavy loads.
Routine checks of coolant level and radiator cleanliness are important to prevent overheating, especially when working in hot or dusty conditions.
You will find the system is straightforward to maintain, with accessible points for coolant top-off and drain.

|---|---|---|
| 540 rpm | 1,902 rpm | Rotary mowers, balers |
| 1,000 rpm | 2,000 rpm | Large spreaders, chippers |
Transmission & Drivetrain
The AGCO LT90 comes with a focus on both power delivery and operator control. You get several features aimed at providing smooth shifting, good traction, and flexibility for a variety of farm tasks.
Transmission Type (Syncro, Powershift, CVT, HST)
The AGCO LT90 is equipped with a 16-speed powershift transmission. This means you can shift through all gears under load without stopping or using a clutch.
Traditional synchromesh and CVTs are not offered on this model. A powershift system is useful when you need to change speeds frequently, such as when baling hay or pulling harvest wagons.
By letting you change gears on the go, you lose less momentum and maintain productivity. The AGCO LT90’s transmission is designed for heavy use, allowing you to handle rough fields or roadwork with less operator fatigue.
Number of Gears / Ranges
You can select among 16 forward and multiple reverse gears, organized into two main power shift ranges. These ranges allow you to fine-tune your speed to match specific job requirements.
The versatile number of gears supports everything from slow fieldwork to faster transport tasks. Precise gear selection helps save fuel during lighter tasks and provides the right torque for tougher jobs.
If you run equipment like mowers or balers, these gear choices give you better control over ground speed and PTO performance.
Top Transport Speed

| Turning Radius (with brakes) | Tight, aided by brake use | Better maneuverability in small spaces |
| Service Brakes | Hydraulic Wet Disc | Durable, needs less maintenance |
| Parking Brake Type | Lever-actuated, mechanical | Secure holding on slopes and flat ground |
Steering System (Hydrostatic / Power-Assisted / Mechanical)
The AGCO LT90 is equipped with power steering. This system uses hydraulic fluid pressure to make steering lighter, so you can turn the wheel with less effort, even when the tractor is carrying heavy loads or attachments.
Hydrostatic steering further reduces physical strain and allows for precise control. You are less likely to experience steering fatigue after long hours of work.
The steering column and wheel are positioned for comfortable everyday operation. This setup also helps you make accurate, smooth turns in tight fields or when moving between rows.
If you need to make small steering adjustments, the system responds promptly.
Turning Radius (with brakes)
Turning capability is crucial for working in confined areas. The AGCO LT90 offers a tight turning radius, especially when you use the brakes to assist with turning.
With power steering, the tractor’s front wheels can angle sharply, allowing you to navigate narrow field paths, ends of rows, and loading yards without repeated adjustments. When you press the turning brake on one side, it helps the inside rear wheel slow down.
This causes the tractor to pivot more sharply around the stopped or slowed wheel, making your maneuver even tighter. This makes headland turns and work near obstacles much easier for you.
If you often operate in orchards, barns, or close around farm buildings, this functionality can save you time and reduce crop or equipment damage from wide turns.
It is useful for loader work as well.
Service Brakes (Wet Disc, Dry Drum, etc.)
The AGCO LT90 comes with hydraulic wet disc brakes. Wet disc brakes operate in an oil bath, which helps reduce heat and wear over time.
They last longer and require less frequent maintenance compared to dry drum brakes. When you press the brake pedal, hydraulic pressure squeezes the discs together, bringing you to a steady stop.
This type of brake is especially helpful if you are carrying heavy loads or working on slopes, where smooth and effective stopping is critical. You do not need to worry as much about loss of braking power due to water, mud, or debris.
The wet disc design keeps contaminants away and ensures consistent performance in all weather.
Parking Brake Type
The parking brake on the AGCO LT90 is a mechanical, lever-actuated system. You engage it by pulling a lever, usually located near the driver’s seat.
Once set, the parking brake locks the transmission or rear brake assembly, holding the tractor in place. This type of brake keeps the tractor stationary on level ground or moderate slopes.
It is especially important when you are getting off the tractor, attaching implements, or leaving the machine parked for long periods. The mechanical setup is simple to check and maintain, adding peace of mind that the tractor will not move unintentionally.
Always make sure to fully engage the parking brake before leaving the seat, especially when stopped on a hill or near other machinery.
Cab & Operator Station
A well-designed cab or operator station keeps you comfortable and in control. Features like ROPS, climate systems, seat quality, and interior noise contribute to safety and long hours of productivity.
ROPS / Cab Option
The AGCO LT90 offers both open and enclosed cab options, allowing you to choose based on your operation’s needs. The standard ROPS (Rollover Protective Structure) meets industry safety requirements and helps protect you if the tractor rolls.
If you are working in unpredictable conditions or uneven ground, having a certified ROPS is critical for your safety. The enclosed cab gives you protection from dust, wind, and weather, which is useful for year-round tasks.
The doors and glass panels are sturdy and provide clear visibility in all directions. This lets you monitor equipment and surroundings easily.
Some models include doors with secure latching and easy steps for getting in and out. The controls in both versions are placed for quick access, reducing the need to stretch or twist while working.
Climate Control (A/C, Heater, Filter)
The enclosed cab on the LT90 comes with a climate control system to keep you comfortable during any season. The air conditioning helps during hot summer months, quickly cooling the interior and letting you focus on your work.
In winter, a built-in cab heater warms the space and keeps windows clear of frost or fog. A fresh air intake and filtration system helps reduce dust and pollen, which can make a big difference if you have allergies or work in dry fields.
The air filter is usually easy to replace or clean, so you can keep the system running at its best. Manual controls for temperature, fan speed, and airflow direction are mounted within reach.
This makes it simple to adjust the temperature while driving, without needing to stop or take your eyes off the job.
Seat & Suspension
You get an adjustable operator’s seat designed for comfort over long workdays. The seat includes fore-and-aft adjustment, so you can move closer or farther from the controls for a good fit.
Some versions come with basic mechanical suspension, which absorbs shocks from rough ground. A higher-spec seat might include upgraded padding, armrests, and swivel functions to let you easily turn and monitor implements.
All major controls and the steering wheel are set up to reduce fatigue, and wide footwells give you room to move your legs or stretch. For taller or shorter operators, height and tilt adjustments help customize the seat position.
A solid floor mat beneath your feet minimizes vibration and helps reduce slipping.
Noise Level (dB A @ operator ear)
The LT90 cab is designed to keep sound levels within a tolerable range. Typical tractor noise at the operator’s ear is about 77–78 dB(A) at no load, according to test data.
This level is low enough to allow conversation but may still require hearing protection after long hours. Open station versions are usually a few decibels louder than cabs, as there is less insulation against engine and road noise.
Cab insulation, rubber seals, and sound-absorbing materials help lower the interior noise. Keeping the cab doors and windows closed keeps most noise outside.
If you prefer a quieter environment, always check cab seals and replace them if worn. Hearing protection is a good idea if you are running the engine at peak power or using noisy implements.

| Noise Level (dB A) | ~80–85 | ~77–78 | Quieter cab lets you work longer comfortably | Hearing protection still recommended |
| Visibility | Open sides | Glass panels, wide view | Easier to see implements and obstacles | Full cab gives all-weather protection |
| Access/Controls | Easy, open entry | Doors, sealed cab | Quick entry/exit, protected controls | Cab has better dust and weather protection |
Hydraulics
The AGCO LT90 uses an open-center hydraulic system, supporting farm work with steady pump flow rates and reliable pressure. You get multiple remote valve options along with a straightforward control layout.
System Type (Open-Center / Closed-Center / PFC)
The AGCO LT90 features an open-center hydraulic system. In this setup, hydraulic fluid flows continuously through the system while the tractor is running.
Pressure is only built up when a valve is activated to move an implement or operate a cylinder. Open-center systems, like in the LT90, are often simpler in design and easier to service compared to closed-center or PFC systems.
For typical field tasks—lifting, tilting, or controlling implements—the open-center layout delivers steady performance. This type of system has fewer complex parts and is less prone to pressure drops when multiple functions are used at once.
Most competitors in this power class also use open-center hydraulics, so you will find it familiar.
Implement Pump Flow (L min⁻¹)
The main implement pump on the AGCO LT90 provides a flow of about 15 US gallons per minute (gpm), which is approximately 56.8 liters per minute (L/min). This pump flow influences how quickly hydraulic cylinders extend and retract, impacting raising and lowering speeds for implements like loaders and rear-mounted equipment.
For most attachments, this flow rate supports efficient operation. Whether you’re handling a loader or operating rear remote hydraulics, the system can provide steady oil flow without major delays in response times.
Most implements for this tractor class will function optimally at these flow rates.
Steering Pump Flow (if separate)
The AGCO LT90 does not use a dedicated steering pump. Instead, steering and implement functions share the same open-center hydraulic pump and oil supply.
This means steering relies on the system’s main hydraulic flow. If you turn the steering wheel while using other hydraulic functions, you may notice a slight dip in implement speed.
However, the design still allows you to steer smoothly during most operations. The layout is simple, lowering service costs since there’s no second pump to maintain.
The oil is returned and recirculated quickly enough to serve both steering and implements during normal conditions.
Total Combined Flow
Since the system uses a single implement pump, the total combined flow is about 15 gpm (56.8 L/min). This covers all hydraulic functions including remote valves and steering.
Here is a table for quick reference:
| Function | Flow (US gpm) | Flow (L/min) |
|---|---|---|
| Implement Pump | 15 | 56.8 |
| Steering Pump | N/A (shared) | N/A |
| Combined Total | 15 | 56.8 |
You must divide this total flow if using multiple hydraulic functions at once. For example, using two remotes or steering while lifting a loader will reduce available flow to each function.
System Pressure (bar / psi)
The AGCO LT90’s open-center hydraulic system runs at pressures suitable for heavy farm equipment. The working pressure usually ranges between 180 to 200 bar (around 2,600 to 2,900 psi).
This level of pressure provides enough force for implements like loaders, backhoes, or hydraulic rams. System pressure is regulated automatically, so you do not need to make manual adjustments.
Relief valves protect the system from overloading and excessive pressure, ensuring safety for both the operator and tractor. If using hydraulic tools or attachments that require certain pressures, always check the compatibility in your implement’s manual.
Remote Valves (number & type)
You can choose either 2 or 4 remote hydraulic valves on the AGCO LT90, depending on your needs and the chosen configuration. These remotes are standard, mechanically controlled double-acting valves.
Each valve allows oil to flow both ways, extending and retracting cylinders on your implements. This number of remotes covers most typical attachments like mowers, balers, planters, and loaders.
Some users opt for 4 valves for more versatility, especially when running multiple rear-mounted implements or using a loader with auxiliary functions. The layout is clear, with remote levers positioned for easy cab access.
You can operate two tools at once if needed, though oil flow will split between active valves. Couplers are standard-fit, so connecting hoses is quick and simple whenever you switch implements.

Three-Point Hitch (3PH)
The AGCO LT90 uses a Category II three-point hitch on the rear, giving you solid lifting ability for heavy-duty implements. This section explains important technical details like hitch type, lift performance, and control options.
| Feature | Specification | Notes |
|---|---|---|
| Hitch Category | Category II | Compatible with medium to large implements |
| Rear Lift Capacity @ Ball Ends | 7,710 lbs (3,497 kg) | 8,885 lbs (4,030 kg) with optional equipment |
| Draft / Position Control | Yes (both available) | Offers fine adjustment and automatic draft control |
| Top-Link Sensing | Not equipped | Relies on standard sensors, not top-link based |
Hitch Category (1 / 1N / 2 / 3)
You get a Category II rear three-point hitch on the AGCO LT90. Category II hitches are made for heavier implements, like plows, cultivators, and large mowers.
The hitch uses the standard Category II pin size, which is 1 1/8-inch (28.7 mm) for the lower pins. This gives you greater stability when working with wider and heavier attachments.
Category II is common on mid-size and larger tractors, so your options for implements are broad. If you plan to use heavier, industrial attachments, the Category II rating ensures that the hitch can take on the stress and load.
This focus on compatibility and strength is important for demanding farm work.
Lift Capacity @ Ball Ends
The AGCO LT90’s rear three-point hitch can lift up to 7,710 pounds (3,497 kg) at the ball ends. If you have the optional heavy-duty lift package, this increases to 8,885 pounds (4,030 kg).
This high lifting power means you can safely handle large implements like subsoilers, disc plows, and loader attachments. Lift capacity is measured at the ball ends, so it shows the actual weight your tractor can raise and hold.
This helps you plan for both transportation and fieldwork. The strong lift cylinders keep the hitch stable under heavy loads, minimizing sway and bounce.
Draft / Position Control
The LT90 gives you both draft and position control. With draft control, the hitch automatically adjusts its height based on the resistance from the implement.
This is important for tasks such as plowing, where the soil changes and you want your tractor to keep the tool at the right depth. Position control lets you set the hitch to a specific height and hold it there.
This is useful when you need precise control, such as when mowing fields or grading. Switching between these two modes is simple and helps you adapt to changing ground conditions quickly.
Top-Link Sensing (Yes/No)
The AGCO LT90 does not have top-link sensing for its three-point hitch. This means that the sensing used for draft adjustments is done through the lower link arms.
Top-link sensing, often found on larger or more specialized tractors, provides even more precise control but is not included here. The standard lower-link sensing works well for most users and keeps maintenance simple.
If your implements require advanced draft response, you may need to look at other tractors with this feature.
Axles & Load Limits
AGCO LT90 tractors are built for strength, reliable heavy-duty use, and optimal performance in demanding field conditions. Knowing the key axle and final drive details can help you avoid overloading your tractor and extend its working life.
Maximum Front-Axle Load (kg)
The exact maximum front-axle load for the AGCO LT90 is not specified in readily available sources. However, this figure is essential if you use front loaders or haul heavy implements.
Exceeding the safe front-axle load can cause balance issues, increased tire wear, or even structural damage. AGCO LT90 tractors use a sturdy front axle to support added weight during loader work, especially if fitted with ballast.
To ensure safe use, always keep loads within the limits stated in your operator’s manual. Regularly check for uneven tire wear or bending on the axle.
Maintaining the right front-axle load protects the steering and suspension system. Try to distribute attachments and front implements in a way that stays within reasonable weight limits, even if the maximum figure is not published.
Maximum Rear-Axle Load (kg)
The maximum rear-axle load is another crucial factor when pulling large implements or carrying rear weights. Precise limits are not always listed, but rear axles are generally designed to withstand heavy pressure from tillage tools or trailers.
For the AGCO LT90, you can expect a rear lift capacity of up to 7,710 lbs (3,497 kg) at the hitch. This shows the rear axle is built for tough fieldwork.
Do not exceed the load recommended for your specific tire size or configuration. Check rear axle bearings and mounts regularly, especially if you use your tractor for hauling.
Stay within lift capacity specifications to avoid excess wear or risk of axle failure.
Final-Drive Type
The AGCO LT90 uses an inboard planetary final-drive system. This type is engineered to handle high torque and heavy loads common in field and transport work.

Tires & Track Options
Choosing the right tires or tracks for your AGCO LT90 is important for getting the best performance, stability, and comfort. The LT90 supports different tire sizes and types to suit agricultural, turf, or industrial needs, and there are additional options for duals and flotation kits.
Standard Front Tire Size (Ag / Turf / Industrial)
Your AGCO LT90 comes with several available front tire sizes based on the work you need to do. Most standard agricultural setups use front tires sized 11.00-16 or 14.9R24, which help with traction in the field.
These tires are built to dig into dirt and provide grip in softer soil conditions. For mowing, landscaping, or working on lawns, turf tire options reduce damage to grass and soft ground.
A typical turf front tire could be sized at 16.5L-16.1. These have a wider surface so they spread the weight of the tractor over more area.
If you need durability for heavy-duty or construction tasks, industrial tread patterns are available. These may use sizes like 12.5/80-18 for better stability on rougher ground such as gravel and hard soil.
Standard Rear Tire Size
Rear tires are larger to support weight and deliver power to the ground. The standard rear tire size for agriculture is often 18.4R34.
These tires are deep-lugged and designed to improve pulling strength, especially in muddy or uneven fields, giving you better control and preventing wheel slip. Turf tires for the rear are wider and have a gentler tread, such as 21.5L-16.1.
These reduce ruts and protect lawns or sod fields while still supporting the LT90’s weight. Industrial options include tires like 16.9-30, which have heavy-duty sidewalls and tougher rubber designed for construction or loader applications.
Optional Duals / Tracks / Flotation Kits
If you work in soft or wet conditions or need to pull heavy implements, you can add optional dual wheels to the rear. Duals improve traction and balance by distributing the load across more tires.
This reduces soil compaction and prevents the tractor from sinking in muddy fields. Track conversion kits are available for some LT90 models, acting as an alternative to wheels.
Tracks spread the tractor’s weight over a larger area and are best for constant soft or marshy conditions. They reduce ground disturbance.
Flotation kits may include low-pressure tires or wide flotation tires. These are designed to operate on sandy, peat, or wet surfaces.
They lower the risk of getting stuck and help protect sensitive ground. Flotation kits also provide a smoother ride.
