Engine Specifications
The AGCO RT145 tractor is equipped with a strong diesel engine built for farming and tough jobs. Attention to engine make, fuel type, displacement, power, torque, and cooling helps you understand its real performance.
Engine Make & Model
You get a Cummins B5.9T diesel engine under the hood of the AGCO RT145. This engine is known for being reliable and easy to maintain in the field.
The B5.9T is part of Cummins’ popular B Series, which is often used in many types of farm and construction equipment. It’s a turbocharged model, so you see stronger power and better fuel use than a non-turbo engine.
Cummins engines are respected for their strong build and simple design. If you already own other machines with Cummins power, you may notice parts and servicing are easier to manage.
Fuel Type & Emissions Tier
Your AGCO RT145 runs on standard diesel fuel. Diesel is chosen for its efficient energy delivery and longer run time, which suits heavy-duty use in fields or on roads.
The emissions tier depends on when your tractor was made. Production of the RT145 started before some strict emissions standards were required.
Many units found in the market have engines meeting EPA Tier II or possibly earlier standards. Emissions control is basic compared to new models.
You likely will not see add-ons like SCR or DEF tanks common on later tractors, making maintenance simpler but meaning higher particulate emission than newer Tier IV tractors. Always check the ID plate or manual for your exact model’s emissions rating.
Cylinders / Displacement
The engine in your RT145 is a 6-cylinder, inline configuration. This setup balances power and smooth engine operation, important for steady field work or heavy pulling.
Each cylinder helps the engine run more smoothly and reduces vibration. The displacement is 5.9 liters (359 cubic inches), a size that provides solid torque and horsepower.
This moderate engine size helps you get strong pulling power without pushing the limits of reliability or fuel use. Inline-six engines like this one are prized for running smoother than four-cylinder engines of similar size.
Rated Horsepower (Gross & Net)
The rated engine horsepower for the RT145 is listed at 161 HP. This is often the maximum output at the flywheel, meaning accessories and transmission haven’t yet drawn power.
You may see a gross rating (actual top output) and a net rating (power available to do useful work). Net horsepower may be around 145 HP after accounting for cooling fans, water pumps, and other engine-driven systems.
The tested drawbar horsepower (power actually delivered to the ground) is about 127.5 HP.
| Specification | Value |
|---|---|
| Engine Model | Cummins B5.9T |
| Emissions Tier | Mostly Tier II or earlier |
| Cylinders | 6 (inline) |

| Steering Pump Flow | Integrated (not separate) |
| Total Combined Flow | 29 gallons per minute (approx. 110 L min⁻¹) |
| System Pressure | 2900 psi (200 bar) |
| Remote Valves | Up to 4; standard and optional, selectable types |
System Type (Open-Center / Closed-Center / PFC)
The AGCO RT145 uses a closed center hydraulic system. In a closed center system, the hydraulic fluid circulates under pressure even when not in use.
This provides quick response to demands from implements. Many modern tractors use closed center systems because they deliver consistent pressure, which can be important for tasks with varying hydraulic needs.
You will find this allows you to run more than one hydraulic function at the same time without losing performance. This system tends to be more efficient than basic open-center designs, since it only uses power when hydraulic functions are in use.
Implement Pump Flow (L min⁻¹)
The implement pump flow for the AGCO RT145 is about 29 gallons per minute (110 liters per minute). This is a high-capacity flow rate suitable for a wide range of implements, such as loaders, mowers, and various hydraulic-powered attachments.
You will notice the strong pump flow especially when using large implements that require steady or constant hydraulic power. Having 110 liters per minute means you have enough capacity for most modern farm tasks without the risk of slow hydraulic responses.
The steady flow helps you achieve consistent lifting, operation, and adjustment of equipment. This is important if you plan to use the tractor for diverse and heavy-duty applications.
Steering Pump Flow (If Separate)
For the AGCO RT145, the steering pump is not a separate unit. Instead, steering functions use the main closed-center hydraulic system.
This integrated design means steering and implement hydraulic demands share the same hydraulic source. This makes steering reliable, as there is always pressurized fluid available for the steering system.
You can expect smooth and responsive steering even when running multiple hydraulic implements. Because AGCO combines the steering and implement flow, you benefit from efficient use of the hydraulic pump.
There isn’t a dedicated flow number for steering as it draws only what’s needed from the main pump.
Total Combined Flow
The AGCO RT145’s total combined hydraulic flow is also rated at 29 gallons per minute (110 liters per minute). This is because the tractor uses a single main pump for both implement and steering hydraulics.
When you operate multiple hydraulic functions at once—such as steering while raising or lowering a loader—the system prioritizes demands based on needs. This combined flow ensures that even under load, the tractor maintains good performance for both control and powered implements.
System Pressure (bar / psi)
The hydraulic system pressure for the AGCO RT145 is rated at 2900 psi (200 bar). This is a high-pressure system that enables you to operate demanding implements requiring significant force.
With a maximum system pressure of 2900 psi, your implements benefit from strong, consistent power. This is especially important for larger planters, heavy loaders, or specialty equipment that relies on strong hydraulic cylinder movements.
The high pressure means that even at lower flow rates, you retain adequate power for lifting and holding heavy loads without hesitation.
Remote Valves (Number & Type)
The AGCO RT145 can be equipped with up to 4 remote hydraulic valves. These are often double-acting and can be ordered with different control types, such as mechanical or electronic controls.
Multiple remotes let you connect several implements or attachments at the same time. You can run a loader, a rear implement, or even additional specialized tools without having to switch hoses back and forth.
The remotes can include adjustable flow controls and detent positions. This gives you flexibility in matching the hydraulic output to the exact needs of your attached equipment.
Most farmers find four remotes more than sufficient for common tasks, but more can sometimes be added through aftermarket solutions.

The RT145’s rear three-point hitch offers a rated lift capacity of 14,500 lbs (6,577 kg) at 24 inches behind the hitch balls. This substantial capacity supports lifting large mounted implements and heavier attachments without straining the tractor.
The lift mechanism uses dual lift cylinders to deliver strong, stable lifting force. This means you can handle bigger implements, such as heavy plows or large seeders, safely and efficiently in the field.
For best performance, ensure the implement’s total weight does not exceed the rated lift capacity. Exceeding this limit increases wear and poses safety risks.
Always refer to your implement’s manual for accurate weight details and safe operation guidelines.
Draft / Position Control
Draft and position control are both standard on the RT145’s three-point hitch. With position control, you set the height of your attachment using the lever in the cab.
This gives you consistent depth for tasks like grading or raking. Draft control measures the resistance (or draft) felt by the implement.
This feature automatically raises or lowers the hitch based on soil conditions to maintain even tillage depth. It is especially useful when plowing, as it prevents the implement from digging too deep or pulling out of the ground.
Using both controls lets you match implement position and traction to variable field conditions. Responsive hydraulic controls improve accuracy and ease of hitch management.
Top-Link Sensing (Yes/No)
The RT145 provides top-link sensing as part of its hitch functionality. This system reads the force applied to the top link by the implement, allowing for advanced draft control.
Top-link sensing automatically adjusts the hitch height, maintaining steady working depth, even as soil hardness changes. Top-link sensing is most beneficial with tillage tools that put variable pressure on the tractor.
By reacting to changes in the field, the tractor maintains optimal traction and consistent implement performance. If your work requires steady depths over changing terrain, you will benefit from this feature.
It adds both convenience and efficiency, especially during demanding jobs like heavy plowing or subsoiling.

For turf setups, the rear tire might shift to something like a 21.5L-16.1. Turf tires in the rear work with the front to prevent ruts and reduce ground pressure, ideal for mowing or landscaping.
If you work in industrial tasks or haul heavy loads, you may prefer a reinforced rear tire in the 16.9-30 or similar sizes. These increase stability and tire life when operating on compacted or rocky soils.
Pay attention to the rim diameter to ensure true compatibility with your tractor’s hubs.
Optional Duals / Tracks / Flotation Kits
You can equip dual rear wheels for the AGCO RT145, boosting traction when handling larger implements. Dual kits allow you to double up on rear tires, which helps with grip and reduces soil disturbance on soft ground.
Tracks are another upgrade option for this model. While the standard tractor uses wheels, aftermarket agricultural rubber track kits can be fitted, especially for high-floatation needs.
Tracks distribute weight more evenly, reducing soil compaction and providing steady pulling on muddy or sandy terrain.
Flotation kits replace standard tires with extra-wide tires, minimizing ground pressure even further. These are crucial if you often work in wet or loose soil.
Kits may include both front and rear flotation tires to help avoid getting stuck or creating deep ruts.

Ground Type (Negative / Positive)
The AGCO RT145 tractor uses a negative ground electrical system. This is standard for most modern agricultural tractors.
The negative terminal of the battery connects directly to the chassis. A negative ground setup improves system stability.
It also allows for easier troubleshooting when you experience electrical problems. Most aftermarket and OEM electrical components, such as lights and wiring harnesses, are designed for negative ground systems.
When servicing your tractor, you need to make sure connections are clean and tight to avoid voltage drops. Loose or corroded ground points can cause starting problems and erratic electronics.
Alternator / Charging System
Your RT145 tractor is fitted with an alternator-based charging system. This is more efficient than older generator types and provides steady charging for all electrical systems during operation.
The alternator is mounted on the engine and uses a belt drive to spin its internal coil. While running, it supplies current to charge the battery and run lights, controls, and accessories.
Modern AGCO alternators are often internally regulated, so the output stays consistent even if the engine speed changes. If you add more electrical accessories, such as extra lights or tech equipment, consider the alternator’s maximum output to prevent overloading.
Charging Output (Amps)
The alternator in the AGCO RT145 typically produces between 120 and 150 amps at peak output. This range provides enough current to keep the battery charged and handle additional electrical loads like work lights, cab fans, and monitoring displays.
If you operate in cold weather or run many electrical devices at once, the charging output is crucial. Too much demand can drain your battery if the alternator is undersized or faulty.
Check the amperage rating on the alternator’s label or in your tractor’s service manual. If electrical accessories are added, upgrading to a higher-output alternator may be necessary.
Battery Voltage
The standard system voltage for the RT145 is 12 volts. This voltage is suitable for heavy-duty starting and running all vehicle electronics.
Most units use either a single large battery or two smaller batteries wired in parallel for more capacity. A 12-volt setup is compatible with common maintenance chargers and booster packs.
When replacing batteries, be sure to match the system voltage to avoid damaging your starter or alternator. Always disconnect the battery before working on electrical wiring.
Test battery voltage regularly to catch weak or failing batteries before they leave you stranded in the field.
Battery CCA Rating
The Cold Cranking Amps (CCA) rating for an AGCO RT145’s battery typically falls between 750 and 1000 CCA. This rating shows how much power the battery can deliver at 0°F for 30 seconds without dropping below 7.2 volts.
A higher CCA rating is recommended if you work in colder climates. Cold starts require more power, especially for a tractor with a high-compression diesel engine.
Always use a battery that meets or exceeds the recommended CCA. Using a lower-rated battery can lead to hard starts, especially in winter, and put extra strain on your starter and charging system.
