Two transmission configurations were available: a standard 8-speed synchromesh gearbox or an optional 16-speed transmission featuring a two-speed 'Torque Amplifier' power shift. The tractor was offered in both two-wheel drive and four-wheel drive variants. It uses an independent rear PTO offering 540/1000 RPM speeds, engaged via a hydraulic wet disc clutch.
Hydraulics and Hitch
The hydraulic system provides a pump flow of 12.4 gpm (46.9 lpm). The rear of the tractor is equipped with a Category II hitch featuring both position and draft control. The standard rear lift capacity is 4400 lbs (1995 kg), which can be increased to 5250 lbs (2381 kg) with the installation of an optional assistor ram.
