Abstract
A control assembly for a work machine is disclosed which includes a movement actuator positionable between a drive position and a neutral position, wherein (i) the work machine is driven by the engine when the movement actuator is positioned in the drive position, (ii) the work machine is prevented from being driven by the engine when the movement actuator is positioned in the neutral position, and (iii) the movement actuator is spring biased into the neutral position. The control assembly also includes a movement actuator retaining device, wherein (i) the movement actuator retaining device includes a retaining actuator positionable between a "reduced friction" state and an "enhanced friction" state, (ii) the movement actuator is maintained in the drive position when the retaining actuator is positioned in the "enhanced friction" state, and (iii) the movement actuator is allowed to move from the drive position to the neutral position due to the spring bias when the retaining actuator is moved from the "enhanced friction" state to the "reduced friction" state. An adjustment assembly for returning the movement actuator to the neutral position and a control switch for enabling and dis…
