ABSTRACT:
A two-speed power-take-off drive for a tractor is disclosed which includes an assembly for sensing and indicating the PTO shaft speed to an operator in the tractor cab. The speed of the PTO shaft is a function of which end thereof is inserted into the drive sleeve, which determines the extent of its penetration into the drive sleeve. A speed indicator arrangement is provided which includes a sensing rod whose movement is controlled by the extent of penetration of the PTO shaft into the drive sleeve. The sensing rod is operative to activate or inactivate an electrical switch. The electrical input condition of the switch serves as an input to the tractor instrument cluster in the tractor cab to indicate the selected PTO shaft speed.
