Transmission

Transmission options
8-speed
12-speed partial power shift

Transmission — partially synchronized

Transmission	partially synchronized
Gears	8 forward and 4 reverse
Four gears (1-4) in high, low, and reverse ranges. Gear shifting is synchronized using the clutch. Tractor must be stoppped to shift range.
With 11-36 rear tires.

Transmission — Agriomatic S

Transmission	Agriomatic S
Type	partial power shift
Gears	12 forward and 4 reverse
The Agriomatic S provides an additional four forward speeds selected by a right-hand power shift lever. Pushing the lever forward engages the Agriomatic range, while rearward uses the conventional range. The Agriomatic speeds are between high and low ranges, so this provides an undershift in high range and an overshift in low range. In reverse range it operates as a power shuttle.
With 11-36 rear tires.
