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.

Steering authority control for a vehicle

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.

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.
