Transmission notes
PowrReverser: PowrReverser uses three ranges, four gears, and a reverser to provide 12 speeds in each direction. The tractor must be stopped, and clutch depressed, to change ranges. The gear can be changed while the tractor is in motion using the clutch. The clutch is not needed to change directions with the reverser lever.
eHydro: The eHydro uses a three-position range lever and two foot pedals, one for forward and one for reverse. The foot pedals must be released, and tractor stopped, to change range.
