A vehicle control system for controlling the height of a linkage on a vehicle having a continuously variable transmission (CVT) in which the linkage is automatically raised and lowered depending on a draft force detected by the vehicle including an input draft force detected by sensors in the CVT or driveline is inputted into the control system and the system further processes said input draft force to provide an output draft force upon which movement of the linkage is based and the control system processes the input draft force by compensating the input draft force detected during acceleration or deceleration and/or compensating the input draft detected whilst travelling along a slope, and/or equalising the input draft force by applying a ramp function, and/or reducing the input draft force when the linkage is at a predetermined height.

A slip control system for an off-road vehicle includes a control system configured to output a signal indicative of a first action if a magnitude of slippage of the off-road vehicle relative to a soil surface is greater than a first threshold value and less than or equal to a second threshold value. Furthermore, the control system is configured to output a signal indicative of a second action, different than the first action, if the magnitude of slippage is greater than the second threshold value.

A control system for controlling pivoting of a header of an agricultural harvester. The control system includes first, second, and third header height sensors, each for mounting to a respective point on the header, each configured to provide a respective header height signal representing a respective measured header height of their respective point on the header above a ground plane. The control system further includes a header angle sensor configured to provide a header angle signal indicative of a pivot angle of the header about an axis; and a processor configured to: receive the signals; calculate an estimated first header height based on the pivot angle and the second and third header heights; determine a replacement first header height by selecting the smallest of the estimated and the measured first header height; and generate a control signal based at least on the replacement first header height.

A tractor includes: a three-point linkage to which a tiller is mountable a hydraulic lifting/lowering driver to lift and lower the three-point linkage, and a mechanical linkage to transmit a lifting/lowering operation amount of the three-point linkage to the lifting/lowering driver. The mechanical linkage includes a load detector to detect an amount of change in traction load via the three-point linkage, a cable to interlock according to the amount of change in the traction load detected by the load detector, and a mechanical linkage interlocked and connected to the cable and the lifting/lowering driver, the mechanical linkage being capable of transmitting the lifting/lowering operation amount according to the amount of change in the traction load to the lifting/lowering driver.
