ABSTRACT:
A conditioning roll mounting structure is disclosed wherein the mounting shaft for the conditioning roll is permitted to be rotatably driven while permitted to reciprocate linearly transversely of the bearing apparatus. A bushing in the form of a support hub having an antifriction surface engaged with a non-circular conditioning roll mounting shaft is pressed within the inner race of a ball bearing whose outer race is secured to the frame of the hay harvesting machine. A drive mechanism can be attached to either the support hub or directly to the shaft provided that provisions are made for accommodating the transversely reciprocating roll movement. The structure permits the conditioning roll to be rotatably supported within the frame of the hay harvesting machine, while being capable of a linear movement between the non-circular conditioning roll mounting shaft and the support hub to which it is mounted. The non-circular mounting shaft can be in the form of splines or standard hexagonal configuration.
