A work vehicle guidance system includes a control system that has a controller having a processor and a memory. The control system is configured to determine a relative location of a work vehicle to a work area. Moreover, the control system is configured to determine an end-of-row turn path for the work vehicle based at least on the relative location of the work vehicle and a minimum turning radius of the work vehicle. The end-of-row turn path is configured to direct the work vehicle to turn from a first main swath of the work area to a headland swath of the work area, travel along the headland swath in direction toward a second main swath of the work area, and turn from the headland swath to the second main swath.

A method of calibrating a hydraulically operated clutch in a continuously variable transmission of a vehicle, includes steps of filling the clutch as if for a shift, using a control signal value for achieving a test pressure, and determining a resulting change in a pressure condition in a hydrostatic power unit of the transmission. If the change indicates initial engagement, then a value representative of the signal value used is recorded. If greater than initial engagement is indicated, or the vehicle moved, then the clutch is emptied and tested using a lower test pressure. If initial engagement is not indicated, the clutch is emptied and refilled to a greater test pressure. An exemplary pressure condition is a difference in pressure in lines between a pump and motor of the power unit. During the calibration, the vehicle can be held stationary with a parking brake or the like.
