ABSTRACT:
A hand control system for a motorized implement such as a snowblower, lawn mower or tiller having a U-shaped handle in which a pair of control levers and a U-shaped bail are pivotally mounted on the handle such that the control levers can be pivoted independently or conjointly by the bail from a first, at-rest, inoperative position distal from the handle to a second, operative position proximate to the handle. The bail co-operates with the control levers to permit sequential activation of one control lever before the other for improved operation of the implement, permits one-handed control of the implement from various positions on the implement handle, and at all times maintains the safety feature of a "deadman" control.
