Abstract
Systems and methods for inhibiting implement-induced stall of a prime mover associated with a turf vehicle. In some embodiments, the vehicle includes an electronic controller (EC) adapted to monitor a speed of the prime mover and detect when the speed falls below a speed threshold. The EC is adapted to automatically disengage a power take-off (PTO) connecting the prime mover to the implement when the speed of the prime mover falls below this speed threshold.
