ABSTRACT:
A control system for controlling an associated device includes a vacuum actuator, connecting means for operatively connecting the vacuum actuator to the associated device, vacuum means for providing a vacuum to the vacuum actuator, and activating means for selectively electrically activating the vacuum actuator. To engage an associated PTO shaft, an operator switches an electric switch opening a control valve and activating a vacuum actuator. Next a clutch arm is pivoted causing a brake arm to take a PTO pulley out of braking engagement and forcing an idler pulley into operative engagement with a PTO belt. This connects the PTO pulley with a drive pulley thereby rotating the PTO shaft. When the PTO is to be disengaged, the brake arm is effective to stop the motion of the implement driven by the PTO, and to stop the implement within a very short time.
