Transmission notes
PowrReverser: Standard transmission, not available with cab. Four speeds with three ranges and reverser lever. Speed changes are synchronized with clutch pedal. Tractor must be stopped, and clutch used, to shift range. Left-hand reverser may be used without clutching.
Sauer-Danfoss eHydro: Controlled by two foot pedals and range shift lever. Tractor must be stopped before shifting ranges. Cruise control standard. SpeedMatch allows maximum speed to be limited. MotionMatch allows acceleration rate to be set. LoadMatch allows engine RPMs to be set, tractor will adjust speed to maintain RPMs.
eHydro AutoHST: AutoHST provides an automobile-style control to the eHydro transmission. A single foot pedal controls engine RPMs and transmission speed, with a column-mounted shifter to select forward, neutral, or reverse.
