ABSTRACT:
A mower-conditioner drive system includes a main support casting having an outwardly projecting stub shaft and an inwardly projecting pivot pin mounted to an upright wall section at one end of a header frame. A slip clutch is received on the stub shaft and includes a main drive plate coupled to one shaft of an angle gear box and includes inner and outer pressure plates connected for being frictionally driven by the drive plate, the inner pressure plate having a main drive spur gear integral therewith and the outer pressure plate having a drive sheave integral therewith. The main drive spur gear forms part of a drive train for driving either a pair of conditioner rolls or for driving an impeller conditioner while the drive sheave is coupled by a belt for driving either a sickle-type cutterbar or a rotary type cutterbar. In the case where the mower-conditioner is equipped with conditioner rolls, the main drive gear is located on the pivot axis of a pair of arms carrying the upper roll for movement towards and away from the lower roll and with one of the pivot arms being mounted on said pivot pin. An angle gear box having a gear ratio between the two shafts thereof which makes it possible to reverse the box so that it delivers the same output speed regardless of whether a tractor PTO connected thereto has a speed of 540 rpm or 1000 rpm is releasably splined to the clutch drive plate.
