International Classification:

A01D 7530

US Classification:

Abstract:

A mower-conditioner includes a header or platform which is equipped with a rotary disc cutter bar having a relatively long length with at least two cutting units being outboard of a central discharge passage where a pair of conditioner rolls are mounted for receiving the cut crop. Aiding in conveying crop to the discharge passage are right- and left-hand sets of three crop converging drums provided at each side of the discharge passage. The outer drums of the two sets are respectively mounted to the top of the right- and left-hand end cutting units of the cutter bar while the other two drums on each side are located behind an inward and rearward extending line that is tangent to the cylindrical path traced by the outer and inner ones of the drums on each side of the discharge passage. In one embodiment, a direct drive transmission is provided, and in a second embodiment a hydraulic motor is provided, for driving the inner two converging drums of each set.

Appl. No.:

10/302161

Inventors:

Michael Joseph Verhulst - Ottumwa IA
John Gregory Petersen - Ottumwa IA

Assignee:

Deere Company - Moline IL

International Classification:

A01D 3403

US Classification:

74640, 56 136

Abstract:

The pinion gears of a rotary cutterbar equipped with a parallel-series arrangement of idler gears and pinion gears includes a pinion gear support pad formed integrally with the bottom wall of the gear housing and located in close relationship to a bottom surface of the pinion gear so as to prevent the latter from moving, once bearing wear or loosening of mounting hardware has occurred, to the extent that rolling elements of a bearing arrangement supporting the pinion drive shaft are permitted to fall out into the gear housing and cause additional damage to the gearing located in the housing.
