The transmission system features 16 forward gears and 8 reverse gears, utilizing a Dual Power power shift mechanism. This synchronized gear setup, paired with a 330mm clutch, allows for efficient speed adjustments in various field conditions. A creeper range was available as an optional feature for tasks requiring low ground speeds.
Hydraulics and PTO
The hydraulic system is an open-center design with closed-center valves, offering a pump flow of 18.2 gpm (68.9 lpm) and a maximum pressure of 2500 psi (172.4 bar). The independent rear PTO provides speeds of 540 and 1000 RPM, allowing for the operation of a wide range of powered implements. The rear three-point hitch (Category II) is capable of a lift capacity of 5,874 lbs (2,664 kg).
