Abstract
A control lever communicates with a plurality of additional levers and an electrical circuit. A PTO brake and electric clutch are responsive to the control lever and circuit for engagement and disengagement. The linkage system includes an electrically responsive inductor and magnetically responsive plate. When the PTO brake is disengaged and the clutch is engaged, the electrical circuit supplies current to the inductor which creates a magnetic field to capture the plate holding the brake and clutch in their respective modes. Upon actuation of the control lever or full application of an associated vehicle's wheel brakes, the circuit is disrupted to the inductor allowing a spring to act upon the linkage assembly to engage the PTO brake and causing the PTO clutch to be disengaged.
