Abstract
A method of automatically controlling a power takeoff shaft of a work vehicle having a hitch includes automatically initiating engagement of the power takeoff shaft as the hitch is lowered such that the power takeoff shaft reaches clutch lockup approximately at a predetermined hitch position setpoint. A method of controlling the engagement of a power takeoff shaft of a work vehicle having a hitch includes calculating a hitch drop time from a first hitch position to a second hitch position based on a hitch drop rate, comparing the hitch drop time to a power takeoff shaft engagement time, and decreasing the hitch drop rate if the power takeoff shaft engagement time is greater than the hitch drop time.
