The machine is available in both two-wheel and four-wheel drive versions, equipped with planetary final drives and differential hydraulic wet disc brakes for reliable stopping power.
Hydraulics and Hitch
The hydraulic system features a pump flow of 7.9 gallons per minute (29.9 lpm), managed through one or two valves depending on the configuration. The rear hitch is a Category II type, providing a lift capacity of 6945 lbs (3150 kg), which enables the operation of a wide array of mounted agricultural implements.
Power Take-Off
The rear PTO is an independent system, offering dual-speed capabilities of 540 and 1000 RPM. The 540 RPM speed is achieved at an engine speed of 1920 RPM, while the 1000 RPM speed is attained at 2000 engine RPM, allowing for efficient use of diverse power-driven equipment.
