in the early 1960"s were farm tractor pto"s inside the tractor transmission with the pto shaft exposed through the transmission case to connect to an auxilliary implement, or were the pto"s separate units that could be attached to the tractor transmission through a removable hatch door? if the pto was an integral part of the farm tractor transmission,could the shaft of an electric motor (the motor mounted on the tractor and not attached to the transmission case)be connected to the pto shaft? the electric motor could then be used to input electrical power into the transmission to move the tractor in a forward motion. the clutch would be disengaged and the electric motor would rotate the pto and the transmission gears and drive shaft to rotate the tractor wheels. if this set-up can be done, would the OEM transmission warranty be violated and cancelled?
