Patent ID: 7861811

Claim:
A drive arrangement for powering a driven implement from a ground wheel on an agricultural machine, the drive arrangement comprising an axle suspension having a housing, a pivoting axle having an inner end supported from the housing and an outer end, a ground driven wheel supported from the outer end for pivoting with the axle, a connecting drive extending between the wheel and the housing, and a drive device extending between the connecting drive and the implement for powering the implement from the wheel, wherein the connecting drive comprises a drive element supported on the axle for rotation with the wheel, a driven element supported for rotation on the housing about a first axis of rotation generally fixed relative to the housing, wherein the driven element rotates on the housing and the angular relationship between the first axis of rotation and the housing remains generally constant as the axle pivots, and a connecting element rotatably supported between the drive element and the driven element, the connecting element having an element axis of rotation and being free-floating for facilitating movement of the element axis of rotation angularly relative to the first axis and to the axle to maintain driving contact between the drive element and the driven element to facilitate pivoting of the axle and wheel relative to the housing while simultaneously providing drive from the wheel to the implement.
