Its parts are housed in a heavy-duty block, and it uses advanced diesel technology to produce high power while keeping fuel use manageable. You benefit from a turbocharged, intercooled diesel with good durability for both field and transport tasks.
Fuel Type & Emissions Tier
The AGCO LT85A runs on diesel, which provides a good balance of efficiency and power. Diesel is ideal for agricultural tractors because it allows long operation hours and stable fuel consumption even under load.
The engine meets Tier III emissions standards, which means it has advanced technology to reduce pollutants. The fuel system uses high-pressure common rail technology to deliver each drop smoothly and efficiently, leading to cleaner burning and consistent performance.
Cylinders / Displacement
This tractor uses an inline 4-cylinder configuration. The engine features 16 valves, allowing more efficient airflow and better combustion.
Because it is turbocharged and intercooled, both performance and fuel economy are enhanced. The total displacement is 4.4 liters (269 cubic inches).
This size is well-suited for tractors in the 100-120 hp category. The larger displacement, combined with forced induction, means you get more torque at lower RPMs, which is important when pulling implements or carrying loads.
Rated Horsepower (Gross & Net)
The gross engine power is 105 horsepower (78.3 kW), as measured at the flywheel before any losses to the drivetrain or auxiliary systems. This measurement is the standard reference when comparing engines.
The claimed PTO power is about 85 hp (63.4 kW). PTO power refers to the power available at the power take-off shaft for implements, which is a real-world value for work applications.
Net horsepower, while not always stated, is usually slightly less due to auxiliary losses but remains above 100 hp.
Peak Torque (Nm @ rpm)
The AGCO SisuPower 44CTA engine produces a peak torque of approximately 410 Newton-meters (Nm) at around 1500 rpm. This high torque at low engine speeds offers strong pulling power, crucial for tasks that require consistent force over long durations.

Transmission & Drivetrain
The AGCO LT85A is designed for flexibility, smooth operation, and reliability in many farm tasks. It features a partial power shift transmission, robust drivetrain options, and practical controls for traction and speed management.
Transmission Type (Syncro, Powershift, CVT, HST)
You get a partial power shift transmission on the AGCO LT85A. This means you can shift through several gears under load without using the clutch.
The core setup combines mechanical gear ranges with hydraulic control for some gears. The power shuttle lets you change direction between forward and reverse quickly.
This function is especially useful during loader work, saving you time while reducing fatigue. This system is not a full powershift but gives more flexibility than a basic syncro mesh transmission.
You do not get infinite adjustment like in a CVT. The focus is on ruggedness and ease of maintenance rather than advanced electronics.
Number Of Gears / Ranges
The LT85A has 16 forward and 16 reverse gears. Gears are organized into four main ranges.
Within each range, there are four power shift gears available. You can shift between these four gears on the go under load, but you will need to stop to shift between ranges.
This setup allows for precise speed control during field work, transport, and loader operations. Whether you need slow speeds for tillage or higher speeds for hauling, you can find the right gear for the job easily.
You won’t encounter complicated gear changes or unnecessary steps, making operation easier for new and experienced drivers alike.
Top Transport Speed
Top transport speed for the LT85A is usually around 25-30 km/h (15-19 mph), but this may vary slightly depending on tire choice and specific configuration. This is a typical transport speed for tractors of this size and class.
You can move between fields or to storage quickly enough without sacrificing control or splitting attention between speed and safety. The transmission ensures the tractor stays stable and predictable even when traveling at higher speeds.
While it is not as fast as some road-optimized tractors, the speed is well suited to most farm tasks.
Drive (2WD / 4WD / AWD)
The AGCO LT85A comes with either 2WD or mechanical 4WD options. The 4WD version provides increased traction and stability, especially in muddy, uneven, or hilly conditions.

Steering System (Hydrostatic / Power-Assisted / Mechanical)
You get power steering on the AGCO LT85A, which means the system uses hydraulic assist to make turning the steering wheel much easier. This cuts down on the effort you need, even when maneuvering at low speeds or handling heavy implements.
The LT85A does not use a mechanical-only or manual steering setup. The hydrostatic assist ensures consistent performance, helping you keep control in rough fields and tight working spaces.
Benefits of the power steering system include:
- Reduced fatigue during long hours of use
- Smooth control in all weather and working conditions
- Improved response when making frequent turns
Turning Radius (With Brakes)
The turning radius of the AGCO LT85A, especially when using the brakes, is designed to let you maneuver efficiently in tight fields or farmyards. You can use individual wheel brakes to create a sharper turning angle, letting you make quick headlands or avoid obstacles.
With both power steering and brake-assisted turning, you can easily guide the LT85A around corners without needing a big open area. This is helpful for row-crop work, loader tasks, or precise operations.
Wheel brakes can lock one side to pivot the tractor’s front end more tightly. This setup is especially valuable when working with implements that require sharp turns or when space is limited.
Service Brakes (Wet Disc, Dry Drum, etc.)
The AGCO LT85A uses wet disc brakes as its primary service braking system. Wet disc brakes are sealed in oil, which keeps them cooled and reduces wear compared to dry drum brakes.
This setup means you get reliable stopping power even in muddy, wet, or dusty conditions. Wet disc brakes also provide smoother and more responsive braking compared to mechanical systems.
They require less maintenance and have a longer lifespan. Hydraulic operation helps make sure you get even brake force on both rear wheels.
The LT85A also can include trailer brakes. Hydraulic trailer brake hookups let you control both tractor and trailer stopping power, which improves safety when hauling heavy loads.
Parking Brake Type
The parking brake on the AGCO LT85A is designed for dependable holding, whether the tractor is parked on level ground or a slope. It usually works by locking the service brake system in place.
This prevents any rolling or unwanted movement, giving you peace of mind when leaving the tractor unattended. The parking brake is activated by a simple lever or pedal inside the operator platform.
Engagement is mechanical, so you don’t need engine power to keep the tractor stopped. The system is made to withstand the pressure of holding heavy equipment or trailers without slipping.

Cab & Operator Station
You can choose between an open ROPS platform or an enclosed cab for the AGCO LT85A. Operator comfort is improved through climate control, updated seating, and manageable noise levels during long days in the field.
ROPS / Cab Option
The AGCO LT85A comes standard with a two-post foldable ROPS (Roll-Over Protective Structure). This setup meets safety standards, giving you protection if the tractor tips.
The foldable design allows the tractor to fit into low buildings or under trees while still providing safety in the upright position. A factory cab is available as an option.
The cab adds weather protection, sound insulation, and extra comfort features. It is equipped with glass panels for visibility and doors on both sides for easy entry and exit.
ROPS comes standard outside the cab option as well, so even with the cab, your tractor meets safety requirements. You can switch between open-air operation for easy access and ventilation, or choose the cab for extra protection and comfort.
The cab is sealed well to keep out dust, wind, and rain, especially useful for use in harsh weather or during long workdays.
Climate Control (A/C, Heater, Filter)
If you choose the cab, climate control is included. The system comes with factory-installed air-conditioning and a heater.
With these controls, you can set the temperature to stay comfortable in both hot summers and cold winters. The air-conditioning uses vents pointed at the operator and major windows to keep glass from fogging.
The heater draws from the engine’s cooling system and can warm the cab quickly in cold weather. There is a built-in air filter in the HVAC system, which helps reduce dust and pollen inside the cab.
The cab’s fans have multiple speeds, so you can adjust airflow as needed. Controls are within easy reach on the side console.
Windows can also be opened for a breeze if you do not want to use the air-conditioning or heater.
Seat & Suspension
The seat in the AGCO LT85A is adjustable to match your weight and comfort settings. You can slide it forward or back, change the recline angle, and adjust the suspension for a smoother ride.
This helps reduce back strain and fatigue during long work sessions. Cabs are equipped with upgraded seats, often adding armrests and additional padding.
Some versions offer mechanical or air suspension, which absorbs vibrations from rough fields and uneven terrain. An adjustable steering wheel and ample legroom make it easy to find a comfortable driving position.
Seat material is designed to resist wear from daily use, dirt, and moisture. If you choose the open ROPS, you still receive similar adjustability but may have fewer comfort features compared to a full cab.
Noise Level (dB A @ Operator Ear)
Noise is an important factor for operator comfort and safety. Inside the cab, sound insulation reduces noise levels noticeably compared to an open ROPS.
The noise level typically falls within the range of 75-85 dB(A) at the operator’s ear while at full engine load. The sealed cab and thicker glass help block out both engine and external field noise.
This allows you to have conversations, listen to the radio, or use a two-way radio system without difficulty. Lower noise exposure also protects your hearing over time.
With the ROPS-only option, noise levels are higher due to lack of soundproofing, usually exceeding 90 dB(A). It’s recommended to use hearing protection for long periods in this setting.
The difference in noise level may influence your choice between an open platform and an enclosed cab.

Hydraulics
The AGCO LT85A uses a robust hydraulic system suited for heavy fieldwork and various implements. The hydraulic setup affects your control, speed, and efficiency when using attachments or steering.
System Type (Open-Center / Closed-Center / PFC)
The AGCO LT85A is equipped with an open-center hydraulic system. This means the hydraulic fluid continuously flows through the pump while the tractor is running, even if no function is activated.
Open-center systems are simpler and generally easier to maintain. In this system, pressure is only built up when you move a hydraulic lever.
This provides a straightforward operation, making it suitable for most farm tasks such as lifting, tilting, or running simple implements. It does not use pressure flow compensation (PFC), so it can’t supply variable flow at constant pressure like some larger tractors.
This system works well for operators who want reliable performance without the complexity of closed-center or PFC systems. It supports a wide range of loader, lift, and rear-mounted implement operations.
Implement Pump Flow (L min⁻¹)
Implement pump flow is important because it determines how quickly implements can operate. On the AGCO LT85A, the implement pump delivers sufficient flow for most medium-sized implements.
You can expect a pump flow rated at approximately 60–70 liters per minute (L/min). This provides solid performance for running single or dual hydraulic cylinders, commonly found in loaders or hydraulic mowers.
If you plan to use equipment that requires higher flow, you may need to evaluate pump capacity based on your needs. With this flow level, most standard farming attachments will raise, lower, or move at a good working speed.
Loader performance is steady and you’ll notice less lag when cycling attachments.
Steering Pump Flow (If Separate)
The AGCO LT85A uses a separate pump for its power steering system. This means steering operations have dedicated flow and pressure, so turning remains light and responsive even during heavy hydraulic use.
The steering pump typically provides around 25–30 liters per minute. This ensures easy handling in tight spaces or when maneuvering with a loaded implement.
Separating the steering pump from the main hydraulic system helps reduce steering effort when carrying out multiple operations at once. This setup benefits you most when performing field tasks that require both lifting (such as loader work) and frequent steering adjustments.
There’s no noticeable drop in steering smoothness, even if you are using the hydraulic remote controls at the same time.
Total Combined Flow
The total combined flow is the sum of both the implement and steering pumps. For the AGCO LT85A, this usually adds up to about 85–100 liters per minute.
With a combined flow close to 100 L/min, you can operate several hydraulic implements and still maintain responsive steering. This lets you work efficiently when running a loader while also powering other tools, like a rear hitch or remote cylinder.
System Pressure (bar / psi)
The hydraulic system operates at a maximum pressure of about 200 bar (2,900 psi). This pressure level allows you to power larger implements without excessive drop in speed or force.
Having higher system pressure helps with lifting heavier loads, moving large implements, and applying consistent force across attachments. The wet disc brakes and clutch in this tractor also leverage this pressure for reliable performance and smooth operation.
This pressure rating gives you confidence that the AGCO LT85A can handle heavier-duty hydraulic tasks, such as bale handling, ground-engaging equipment, or high-demand loader attachments.
Remote Valves (Number & Type)
The AGCO LT85A comes standard with at least two rear remote valves, but some models or options may offer up to four. These valves are double-acting, allowing oil to flow in both directions, which is useful for a range of implements.
Double-acting valves let you extend or retract cylinders with equal power and speed. Common uses are for loader arms, rear mowers, or hydraulic top links.
The number of valves determines how many implements you can operate independently. If your work requires more than two remotes, you can often upgrade before purchase or add aftermarket kits.
Each remote valve usually features easy lever controls within the cab.

- Ball End Capacity: Strong enough for most large implements
- Support: Suited for tough, high-weight applications
Draft / Position Control
Your LT85A comes with both draft control and position control as standard features. Draft control automatically adjusts the hitch height based on the resistance from the soil.
This keeps tillage implements at a constant working depth, which helps maintain good traction and reduces wheel slip. Position control lets you set and hold the three-point hitch at a specific height or position.
This is useful for carrying implements or setting the working depth exactly as needed.
Key points:
- Draft Control: Yes (automatic height based on soil load)
- Position Control: Yes (manual set height)
- Benefits: Consistent depth, less slip, higher accuracy
Top-Link Sensing (Yes/No)
The AGCO LT85A does not feature top-link sensing as part of its standard three-point hitch system. Top-link sensing is an advanced feature mostly found on high-end tractors with sophisticated draft control.
It uses the movement and force on the top link to fine-tune how much the hitch lifts or lowers in real-time. While the LT85A does not include this, its standard draft and position controls are reliable and give you good accuracy for most applications.
If you require top-link sensing, you may need to look for retrofit kits or consider more premium models.

Maximum Front-Axle Load (kg)
The front axle manages weight from the engine and front-mounted equipment. On the AGCO LT85A, the front axle is designed for durability, especially when using a front loader or ballast weights.
For most mid-sized tractors in the 105 hp range, the front-axle load tops out around 2,800 kg. This lets you add heavy attachments or front weights, but staying within the limit is key.
Exceeding the maximum load can cause premature wear, steering issues, or even axle damage. Always refer to your operator’s manual for the minimum and maximum recommended front-axle loads for safe operation.
When using 4WD, the LT85A’s front tread width is adjustable from 61 to 85 inches (154 to 215 cm), giving you flexibility for stability and different tasks.
Maximum Rear-Axle Load (kg)
The rear axle carries most of the tractor’s weight, including implements mounted on the three-point hitch. For the AGCO LT85A, a typical maximum rear-axle load is up to 4,500 kg.
This figure is common for tractors in its weight and horsepower class. Staying within this limit is critical when towing heavy machinery or carrying large implements.
When a cab or heavy ballast is added, rear loads may approach this maximum. Overloading can cause axle stress or even failure, so always check your load distribution.
The LT85A offers a rear tread adjustment from 60 to 84 inches (152 to 213 cm), aiding in stability. The flange-type rear axle delivers strength and can handle wide tires for better traction while still maintaining proper load support.
Final-Drive Type
The AGCO LT85A uses an outboard planetary final drive system. This design helps distribute stress across planetary gears at the end of the axle, which gives high durability under heavy loads.
The final drive arrangement is critical for delivering the full 105 hp to the ground without overloading internal gears. The flange-style axle at the rear combines with the planetary drive to offer a balance of strength and adaptability.
This setup supports heavy fieldwork duties, frequent load changes, and enables easier maintenance.

Tires & Track Options
Choosing the right tire or track setup affects traction, comfort, and how well your tractor handles different field conditions. Tire sizes and options can also impact flotation and compaction, which matter for both field work and transport.
Standard Front Tire Size (Ag / Turf / Industrial)
For agricultural (Ag) use, the AGCO LT85A comes with 13.6R24 front tires if you select the 4WD version. This size gives a good balance between grip and soil protection.
If you choose the 2WD setup, the typical Ag front tire is 10.00-16, which is narrower and better suited for row crop work. Turf and industrial tires are also available, but specific sizes are less common than Ag variants.
Turf tires typically have a wider tread and lower profile to protect grass or sod, while industrial tires usually offer a heavier tread for hard surfaces and challenging conditions like construction sites.
If you mainly operate on fields with soft soils, an Ag tread is recommended for its traction and self-cleaning properties. For operations on turf or mixed grounds, you may consider turf or industrial options depending on your needs.
Standard Rear Tire Size
The standard rear tire size on the AGCO LT85A is 18.4R30 for both 2WD and 4WD models. This size is popular for mid-size tractors and gives a strong footprint for traction.
The wider tread helps with stability and reduces soil compaction under normal field loads. The R30 means a rim diameter of 30 inches, which is typical for this class of tractor.
The 18.4 width offers a balance between pull and floatation. Rear tires with Ag tread are the most common, but turf and industrial patterns can be ordered through specialty dealers or aftermarket options.
When selecting rear tires, matching the width and tread to your ground conditions is important. Wider tires help with flotation in wet fields, but may not fit all row spacings or implements.
Optional Duals / Tracks / Flotation Kits
Optional dual rear wheels can be added to the LT85A for increased traction and reduced ground pressure. Dual wheels are most useful in wet conditions or when working with heavy loads.
They also improve stability on hillsides and when hauling large implements. Rubber tracks are not standard for this model, but some aftermarket kits allow you to convert the axle to accept tracks or larger flotation tires.
These options can greatly reduce soil disturbance and are beneficial in soft ground or for specialty crops. Flotation kits include wider or low-pressure tires and may be installed front and rear.
This setup is designed to minimize soil compaction, especially in muddy or loose soils. Some farmers also combine front and rear flotation kits for light tillage or planting work.
Below, you can see a comparison of the main tire and option choices for the AGCO LT85A:
| Feature/Option | Front Tires | Rear Tires | Optional Equipment |
|---|---|---|---|
| Standard Ag (4WD) | 13.6R24 | 18.4R30 | None |

Wheelbase
The wheelbase of the AGCO LT85A is 105 inches (266 cm). This distance between the centers of the front and rear axles offers stability especially when working on uneven ground.
A longer wheelbase generally helps you with smoother rides over rough areas, reducing bouncing and jolting. Stability in the field supports safe use when carrying loads on the rear, like plows or seeders.
The 105-inch span also plays a major role in the tractor’s turning radius. Although this is not a compact tractor, the length is carefully balanced for row-crop work, helping you navigate fields and turn at headlands.
Wheelbase size influences traction as well. You’ll notice improved grip in loose soil and heavy-duty field tasks.
With the AGCO LT85A, this specification aligns well with its power output and heavy-duty build.
Overall Length
The full length of the AGCO LT85A is 172 inches (436 cm). This measurement spans from the front weight bracket or bumper to the rear hitch.
A longer tractor body means more space for mounting implements and better weight distribution across axles. With 172 inches, you have enough room for front and rear attachments, including larger seeders or hay equipment.
This overall length affects maneuverability when turning at rows’ ends. While it isn’t a compact size, everyday work like hauling, towing, or lining up to trailers stays manageable due to well-designed steering and balanced proportions.
Transport is another consideration. The 172-inch length means the tractor might require special attention when moving on smaller trailers or through narrow gates.
Check clearances before road transport.
Overall Width (Minimum Tread)
The minimum tread width, or overall width, is 79.3 inches (201 cm) for the AGCO LT85A. This reflects the narrowest setup for tires and wheels.
Your overall width affects how the tractor fits between rows and through tight spaces. With just over 79 inches, the LT85A can handle row crops as well as wider open field work.
This width also impacts stability, especially on hilly ground. Wider tread settings mean less chance of tipping, but 79.3 inches is still very stable for most farm conditions.
Always check that your minimum tread width matches your field row spacing to avoid crop damage. Transport through gates or on rural roads is influenced by the overall width too.
At just under seven feet, you can move through many standard farm gates, but always measure first.
Adjustable tread spacings are available, so you can set the tractor for your needs. The minimum is a useful starting point for general field work.
Height To ROPS / Cab
The LT85A comes in different height configurations. With the ROPS (Roll-Over Protective Structure) folded, it stands 62.5 inches (158 cm) tall.
If you have the cab installed, the height is 109 inches (276 cm). A lower ROPS height is helpful for working in barns or sheds with low entryways.
Folding the ROPS allows you to drive in and out without worrying about hitting low ceilings or beams. With the cab, the height increases significantly, giving you more headroom and space for controls and visibility.
The cab also protects you from weather while in the field. At 109 inches, clearance under barns or tree branches becomes important, so measure overhead spaces before moving.
Both the ROPS and cab options have safety considerations. The ROPS design helps keep you protected in case of an overturn, and cab models include full weather protection with visibility.
Choose the height that matches your workplace—ROPS for flexibility of movement, cab for comfort and conditions where extra clearance isn’t needed as much.
Ground Clearance
Ground clearance for the AGCO LT85A varies based on tire choice and axle setup, but a typical clearance is around 17 to 18 inches. Higher ground clearance gives you better ability to drive over crop stubble, small obstacles, and uneven ground.
This prevents damage to the underbody or transmission, especially in tall crops or tilled fields. You’ll find that good clearance matters for row cropping, where plant height and rough terrain require the tractor to ride over materials without dragging.
With about 17-18 inches, you can operate in most field and farmyard situations without issues. If you regularly use the tractor in muddy or challenging terrain, higher clearance helps prevent getting stuck.
Check your specific LT85A setup and tire type, as these can affect the actual number.
Shipping Weight
Shipping weight refers to the tractor without cargo, fluids, or attachments. For the AGCO LT85A, shipping weight ranges from 8,958 lbs (4,063 kg) for 2WD ROPS models, up to 10,115 lbs (4,588 kg) for 4WD cab models.
The difference in weight depends on options and equipment. Two-wheel-drive models are lighter for easier transport and basic field work, while four-wheel-drive and cab-equipped models offer more stability and comfort but weigh more.
Knowing the shipping weight helps with transport planning, trailer choices, and moving the tractor between fields or farms. Heavier models might need bigger trailers and stronger tie-downs.
Consider your towing and hauling equipment when choosing a model.
Operating Weight (With Fluids)
Operating weight includes all fluids like oil, coolant, and a full fuel tank. For the AGCO LT85A, this is from 9,608 lbs (4,358 kg) to 10,115 lbs (4,588 kg), depending on configuration.
Operating weight matters because it reflects the tractor’s true, ready-to-use mass. Heavier weight helps increase traction, reduce wheel slippage, and keep you stable during tough jobs.
When attaching heavy implements or pulling loads, always use the operating weight as your baseline. This weight is crucial for calculating safe towing capacity, braking distances, and field performance.
If you add ballast or extra equipment, total operating weight increases further. Always make sure your transport equipment matches the loaded operating weight to ensure safety both on and off the farm.
Fuel & Fluids
To keep your AGCO LT85A running efficiently, it is important to understand its fuel and fluid systems. The fluid levels, tank capacities, and types all matter for performance and maintenance.

Fuel-Tank Capacity
The AGCO LT85A is fitted with a standard diesel fuel tank that holds 38 gallons (143.8 liters). This allows you to work for many hours without needing to refuel often.
If you have a larger operation or want even longer intervals between fill-ups, there is an optional 50-gallon (189.2 liters) fuel tank available. Diesel is the only fuel you should use, and the LT85A’s high-pressure common rail system helps the tractor use fuel more efficiently.
Always use clean, fresh diesel to avoid clogging the fuel filters or harming the engine. When planning your work, consider your average fuel use, which is about 5.4 gallons (20.4 liters) per hour under normal conditions.
Keeping the tank above a quarter full helps reduce condensation and air in the fuel system.
DEF-Tank Capacity (If Applicable)
The AGCO LT85A does not have an SCR system and does not require Diesel Exhaust Fluid (DEF). You do not need to worry about filling or maintaining a DEF tank for this model.
This can simplify your maintenance routine compared with newer models that require DEF. Since there is no SCR or DEF system, you have fewer steps in your daily checks and no risk of DEF contamination.
Simply focus on good diesel fuel for your engine. If you are moving from a newer tractor with DEF, you may notice less downtime and simpler maintenance.
Engine Oil Capacity
Your AGCO LT85A tractor relies on regular engine oil checks and changes to protect its 4.4-liter, 4-cylinder turbocharged diesel engine. The specific oil capacity can be found in the operator’s manual, but it generally ranges from 11-13 quarts (approximately 10.4-12.3 liters).
Check the oil level before each use to prevent engine wear. Use the recommended engine oil weight and follow the manufacturer’s change intervals.
Always use an oil that meets or exceeds AGCO’s service class for best results. Proper oil level ensures cooling and lubrication.
After each oil change, run the engine for a few minutes, then recheck the oil level and add more if needed.
Hydraulic/Transmission Oil Capacity
The LT85A uses a dedicated hydraulic and transmission oil reservoir. The capacity may vary, so it is important to reference your operator’s manual for the exact fill amount.
Always use AGCO-specified hydraulic/transmission oil for optimal system protection. Maintaining the correct fluid level in the hydraulic system is crucial.
Low or dirty hydraulic oil can cause slow or jerky operation and may damage pumps or valves. Regularly inspect both the fluid level and condition, adding or replacing oil as needed.
Keep filler necks and dipsticks clean before checking or adding oil to avoid contamination. Always use filters and oil types recommended by AGCO to ensure reliability and smooth operation in the hydraulics and transmission.
Electrical System
The AGCO LT85A tractor relies on a modern electrical system to keep its engine running, power its electronics, and ensure starting reliability in different conditions. Each main electrical component is designed to support performance and durability.

| Battery Voltage | 12 Volts |
| Battery CCA Rating | 650–950 Cold Cranking Amps (varies by battery model) |
Ground Type (Negative / Positive)
The AGCO LT85A uses a negative ground electrical system. This is the common standard for most farm tractors and vehicles.
A negative ground system means the tractor’s chassis is directly wired to the negative terminal of the battery. The positive terminal powers the starter, alternator, lights, and electronic devices.
This setup helps to reduce corrosion on connectors and improve circuit reliability. You can easily connect accessories and testing equipment to a negative ground system.
Replacement parts are also easier to find because most aftermarket parts are designed for negative ground.
Alternator / Charging System
Your AGCO LT85A tractor is equipped with a 12-volt alternator-based charging system. The alternator provides steady electrical current to power the tractor’s lights, controls, and electronics, while also charging the battery during operation.
The alternator has a built-in voltage regulator that keeps the system voltage stable. This helps prevent damage to wiring and components from voltage spikes or drops.
The alternator belt must be kept tight and in good condition for efficient charging. The alternator is typically mounted on the side of the engine.
If you notice dim lights or frequent battery discharge, check the alternator and its connections.
Charging Output (Amps)
The typical charging output for the AGCO LT85A’s alternator ranges from 65 to 90 amps. This is enough to support the power demands for starting, running headlights, cab controls, warning lights, and any extra electrical attachments.
High charging output is important on tractors using electronic controls or added implements. Monitor the amp output with a voltmeter or shop diagnostic tool.
If amperage output drops below normal, it may indicate worn brushes or a failing regulator.
Battery Voltage
The AGCO LT85A uses a 12-volt battery system. All major electrical components, including the starter, ignition, lighting, and control systems, are designed to work at this voltage.
A 12-volt system allows easy jump-starting with standard cables if starting trouble occurs. You need to ensure the battery terminals are clean and connections are tight to maintain good power flow.
Always disconnect the negative cable first when servicing electrical components to prevent accidental shorts.
Battery CCA Rating
The recommended battery for the AGCO LT85A should have a Cold Cranking Amps (CCA) rating between 650 and 950 CCA. CCA measures how well a battery can supply power in freezing temperatures, which is critical for diesel engine starting in cold weather.
A higher CCA rating improves starting reliability, especially as batteries age. Match the rating to your local climate and the tractor’s use for best results.
Check the battery label for CCA specification before replacement. If you operate in very cold areas, a higher CCA battery can make a significant difference in cold starts.
Total Cost Of Ownership Metrics
When using the AGCO LT85A tractor, the real costs involve more than the purchase price. Key factors include how often you service it, what maintenance costs you can expect each year, how quickly it loses value, and how much fuel it uses under work conditions.
Recommended Service Intervals
For reliable operation and a longer tractor life, you need to stick to AGCO’s scheduled service plan. Change the engine oil and replace the oil filter every 250 hours.
Inspect and clean the air filter at least every 100 hours, and replace it as needed. Transmission and hydraulic fluids should be checked every 50 hours and changed every 1,000 hours.
Grease fittings, check tire pressure, and examine belts and hoses every 10 hours of use. Electrical connections and battery terminals require inspection monthly.
Estimated Annual Maintenance Cost
Annual maintenance costs depend on how much you use your LT85A, but a typical figure is approximately $1,200 to $1,500 for regular use (between 300–500 hours per year). This amount covers fluid changes, filter replacements, tire care, and minor parts like lights or fuses.
In the first few years, costs are mainly routine. As your tractor ages, you might face higher expenses for things like worn hydraulic hoses, battery replacement, or clutch work.
Setting aside an annual maintenance budget will help avoid large, unexpected repairs.
Depreciation Curve (% Per Year)
Tractors like the AGCO LT85A generally lose value over time, but the curve is moderate if you maintain it well. In the first year, you can expect a depreciation rate of 15–20%.
From the second through fifth years, depreciation slows to about 6–8% per year. After five years, the rate tapers to 3–5% per year.
Regular servicing and keeping good records can slow the loss of value. Tractors with lower hours or in better condition tend to fetch higher prices in the used market.
Fuel Consumption @ Rated Load (L hr⁻¹)
The AGCO LT85A uses a 105-horsepower diesel engine. At rated load, you should expect fuel consumption around 15 to 18 liters per hour (L/hr).
Actual use will vary depending on workload, field conditions, and how well the tractor is maintained. Lighter tasks consume less, but heavy plowing or hauling at full throttle pushes fuel use to the upper end of this range.
Keeping filters clean and tires at the correct pressure can help reduce how much fuel you use each hour.
