  • Patent number: 7419011
    Abstract: The present invention provides a small electrical motor, coupled to the snow plow of a UTV or ATV via a mechanism which allows the plow blade to move in response to unexpected spikes in load. In one embodiment, a braking system is used to absorb the load force. In a second embodiment, a set of pulleys is used in conjunction with a belt, such that the belt will slip in the presence of excessive force. In a third embodiment, a rack and pinion mechanism is used in combination with a spring element to absorb the excessive load.

  • Patent number: 7351028
    Abstract: Adapter for mounting on a work machine comprising an attachment for individually attaching one or more working implements to the work machine and allowing lateral rotation or tilting of the working implement, thereby raising one lateral end of the implement while simultaneously lowering the opposite lateral end. The adapter can be permanently mounted to the work machine (and remains dormant when not in use), or can be removably mounted thereto.

  • Patent number: 7260902
    Abstract: Jack for raising and lowering a working implement such as hydraulically driven snow blades or other utilitarian accessories. Actuation of the jack allows for proper vertical alignment of the lift assembly for engagement to a vehicle chassis. Once engaged, the jack can be actuated into an inoperative position until the lift assembly is to be removed from the chassis.

  • Publication number: 20040118621
    Abstract: A hydraulic system for an off-road vehicle such as a utility terrain vehicle. The hydraulic system of the present invention is coupled directly to the torque converter of the vehicle, and drives a hydraulic pump that provides both continuous hydraulic fluid as a power source (for working implements such as a jack hammer or hydraulic chain saw) and intermittent hydraulic fluid as a power source (to raise and lower a snow plow blade, for example). A clutch is used to engage or disengage the hydraulics when desired.

  • Patent number: 6240659
    Abstract: Control system for a jack for raising and lowering a lift assembly for hydraulically driven snow blades or other utilitarian accessories. Actuation of the jack allows for proper vertical alignment of the lift assembly for engagement to a vehicle chassis. Once engaged, the jack can be actuated into an inoperative position until the lift assembly is to be removed from the chassis. The control system includes several safety features that prevent the jack from being deployed when the snow blade is raised, and that automatically retract the jack when the snow blade is raised.
