I've gotten used to the Kubota system. It's OK. It sure helped when they went to the newer shaped pedal. Our
M59 was one of the first to have the differently shaped single pedal that only uses the toe of your foot to engage either Fwd or Rev while your heel move back and forth on the floorboard.
It took some getting used to. Unlike JD and other two pedal systems where you swing your foot from side to side to change directions, in the Kubotas with the new shape pedal you move your foot forward and backwards. Both systems use your toes; if someone has the old heel/toe rocker type pedal and doesn't like it you ought to be able to change the pedal. Mines just held on with a cotter pin. I didn't think that old heel/toe rocker type pedal was still OEM on anything.
The Kubota does have one thing going for it. When using their single pedal it is impossible to engage forward and reverse at the same time. Maybe they think that is important for the HST.
