Abstract
A harvesting attachment includes a supporting frame, which is movable in a forward direction over a field. A pick-up device is attached to the supporting frame for picking up crop produce from the field. A height-adjustable cross-feeding auger is attached to the supporting frame. The cross-feeding auger is driveable by a drive shaft rotatably supported on the frame. A telescopic cardan shaft is arranged between the drive shaft and the cross-feeding auger to communicate torque therebetween.

A harvesting attachment for a harvesting machine, the harvesting attachment comprising:
- a supporting frame movable in a forward direction over a field;
- a cross-feeding auger moveably attached to the supporting frame for relative movement therebetween;
- a drive shaft rotatably supported on the supporting frame;
- a telescopic cardan-shaft interconnecting the drive shaft and the cross-feeding auger for transmitting torque therebetween;
- wherein the cross-feeding auger defines an end cavity, with the telescopic cardan shaft disposed within the end cavity of the cross-feeding auger;
- and
- wherein the cross-feeding auger is rotatably supported at both ends by respective bearings disposed on a respective rocker that is attached to the supporting frame at respective pivot bearings with respective axes of rotation extending in the transverse direction.
A harvesting attachment for a harvesting machine, the harvesting attachment comprising:
- a supporting frame moveable in a forward direction;
- a cross-feeding auger moveably attached to the supporting frame for relative movement therebetween;
- a drive shaft rotatably supported on the supporting frame for rotation about an axis transverse to the forward direction;
- a telescopic cardan-shaft having a first universal joint coupled to the drive shaft, a second universal joint coupled to the cross-feeding auger, and a telescopic section disposed between the first universal joint and the second universal joint, wherein the telescopic cardan-shaft is operable to transmit torque between the drive shaft and the cross-feeding auger;
- and
- wherein the cross-feeding auger includes a tube defining an end cavity therein, with the telescopic cardan-shaft disposed within the end cavity of the tube of the cross-feeding auger.
