Abstract
An agricultural vehicle includes a chassis, a header carried by the chassis, an operator cab carried by the chassis, wheels carried by the chassis, at least one wheel driver coupled to at least one of the wheels and configured to drive the at least one coupled wheel at a wheel drive speed, a control handle placed in the operator cab that is displaceable from a zero speed position to a maximum speed position, and a controller operably coupled to the at least one wheel driver. The controller is configured to receive a header type signal indicating a header type of the header and output a resolution signal to the at least one wheel driver to define the maximum speed amount based at least partially on the received header type signal.
Claims14
An agricultural vehicle, comprising:
- a chassis;
- a header carried by the chassis;
- an operator cab carried by the chassis;
- a plurality of wheels carried by the chassis;
- at least one wheel driver coupled to at least one of the wheels, the at least one wheel driver being configured to drive the at least one coupled wheel at a wheel drive speed;
- a control handle placed in the operator cab, the control handle being displaceable from a zero speed position to a maximum speed position and operably coupled to the at least one wheel driver such that displacement of the control handle from the zero speed position to the maximum speed position changes the wheel drive speed by a maximum speed amount;
- and
- a controller operably coupled to the at least one wheel driver, the controller being configured to:
- receive a header type signal indicating a header type of the header;
- and
- output a resolution signal to the at least one wheel driver to define the maximum speed amount based at least partially on the received header type signal.
A method of adjusting a speed resolution of a control handle of an agricultural vehicle, the agricultural vehicle comprising a plurality of wheels, at least one wheel driver coupled to at least one of the wheels and operably coupled to a controller, and a header, the method being performed by the controller and comprising:
- receiving a header type signal indicating a header type of the header;
- and
- outputting a resolution signal to the at least one wheel driver to define a maximum speed amount at which the at least one wheel driver drives the at least one coupled wheel, the resolution signal being based at least partially on the header type signal, the control handle being displaceable from a zero speed position to a maximum speed position and the at least one wheel driver being configured to drive the at least one coupled wheel at the maximum speed amount when the control handle is at the maximum speed position.
