Abstract
A vehicle having a linkage for attaching an implement including a control system for controlling a draft mode of operation in which the linkage is automatically raised and lowered depending on a draft force detected by the vehicle and a lifting cylinder, and when the vehicle travels at low speeds, or is driven in reverse or is stationary, the control system automatically sets the detected draft force to zero and the draft control mode of operation is maintained.
Claims15
A vehicle controlling a linkage for controlling the raising and lowering of a soil-engaging portion of an implement, the vehicle comprising a control system for a draft control mode of operation in which at least one linkage is automatically raised and lowered depending on a draft force detected by the vehicle, said at least one linkage comprising a lifting cylinder, characterised in that when the vehicle travels at low speeds, or is driven in reverse or is stationary, the control system automatically sets the detected draft force to zero and the draft control mode of operation is maintained.
A control method for a draft control mode of a vehicle controlling at least one linkage to raise and lower a soil engaging portion of an implement, the method comprising the steps of:
- detecting a draft force experienced by an implement provided at the vehicle;
- providing a draft control mode of operation for the vehicle, in which the at least one linkage is automatically raised and lowered depending on a detected draft force;
- monitoring the movement of the vehicle;
- and
- setting the detected draft force to zero when the vehicle travels at low speeds, is driven in reverse, or is stationary, for maintaining the draft control mode of operation.
