Abstract
A power-take-off of a utility vehicle such as an agricultural tractor has a clutch (3) and a brake (18) to retain the output shaft against rotation when the clutch is disengaged. The invention provides a means of automatically disengaging the brake to permit rotation of the output shaft for the purpose of coupling an implement thereto. In one embodiment, the clutch and brake are engaged by fluid under pressure, and are disengaged by stopping the vehicle engine and thus allowing engine generated fluid pressure to decay.
