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.
Claims9
A control system for a motorized implement comprising:
- (a) a U-shaped handle;
- (b) two control levers, pivotally mounted on the U-shaped handle, one end of each being pivotally moveable from a first inoperative position distal from the handle to a second operative position proximate to the handle;
- (c) a U-shaped bail, pivotally mounted on the U-shaped handle, the bight of which being pivotally moveable from a first inoperative position distal from the handle to a second operative position proximate to the handle, said bail adapted to bear against the control levers and move them from their first positions to their second positions when the bail is pivoted from its first position to its second position;
- and
- (d) means for normally biasing the control levers and for biasing the U-shaped bail to their first positions distal from the handle;
- whereby each control lever may be independently pivoted from its first to its second position;
- or both control levers may be conjointly pivoted by the bail from their first to their second positions.
