Abstract: A vehicle includes a rear steering system and a front differential hydraulic drive system. A first front drive control valve is operable to output a defined fluid flow in response to a steering command input. A second front drive control valve is operable to selectively divert a portion of the defined fluid flow output from the first front drive control valve. When the vehicle is operating in a pre-defined condition, a steering controller may control the second front drive control valve to divert a portion of the defined fluid flow from the first front drive control valve to define a reduced fluid flow, which is communicated to the front differential hydraulic drive system, to reduce a steering ratio of the front differential hydraulic drive system relative to the rear steering system, to desensitize steering provided by the front differential hydraulic drive system.

Abstract: A conditioner roller vibration sensing mechanism having first and second rotatable conditioner rollers spaced apart in close proximity to each other and between which cut crop can be directed as the rollers rotate during operation. The first roller is shiftable with respect to the second roller for adjusting the spacing between the rollers. The rollers vibrate when the rollers are spaced in such close proximity to each other that they contact each other as they rotate. An arm pivotally mounted to a frame supports the first roller, and the frame supports the second roller. The arm is movable to shift the first roller with respect to the second roller. An accelerometer is operatively coupled to the rollers for sensing the vibration created when the first and second rollers are positioned so close to each other to contact each other.

Abstract: An agricultural harvester includes a draper cutting platform, and a traction unit carrying the draper cutting platform. The traction unit includes an operator station and a hydro handle within the operator station. The hydro handle includes a reverse shuttle switch which is manually actuatable by an operator to selectively reverse a travel direction of at least one movable component on the cutting platform.

Abstract: An agricultural harvester includes a base unit and a header coupled with the base unit. The header includes a frame; at least one draper belt; a header lift detector providing an output signal indicating a lift state of the header; and a draper belt accelerator receiving the output signal from the header lift detector and accelerating each of the draper belts upon receipt of the output signal.
