A control device for controlling the position of a snowplow mounted on the front of a vehicle is disposed in the cab of the vehicle and is selectively mountable in any one of a plurality of locations in the cab to facilitate access to the control device in accordance with the preference of the vehicle and snowplow operator. The control device includes a housing supporting manually operable pushbutton switches which control the selectable plow positions. The housing is provided with one component of a two component separable fastening arrangement, the second component of which is mounted in the cab in one or more of a plurality of selectable positions, such as on the dashboard, armrest, console, gearshift lever or clothing worn by the vehicle operator, whereby the control device can be positioned in a location most convenient to the operator. The control device includes switches controlling solenoid actuated valves by which the position of the snowplow blade is adjusted and includes circuitry operable when the blade is lowered to contact ground to bypass the corresponding switch such that the blade is maintained in a floating mode.

A plow is constructed of a curved high density polyethylene moldboard and frame assembly. The moldboard can be constructed with a mounting collar that slides over and grips the frame or with the frame molded into and encapsulated by the polyethylene. A scraper blade is attached to the bottom of the frame for increasing the moldboard's ridigity and/or securing the moldboard to the frame.

Plastic moldboards for snowplows and the like

A lift mount assembly is provided for a plow blade unit mounted on the frame of a vehicle. The assembly includes a housing unit which is permanently attached to the vehicle frame beneath and behind the bumper including two tube members extending away from the vehicle and similarly recessed. A support unit is designed to be quickly removed from or attached to the housing unit by two tube ends insertable into the housing unit tube members and held in place releasably. The support unit includes a specially configured tube extending forwardly then upwardly away from the vehicle where each end is attached, and meeting at a bight portion. A tubular brace member is spaced apart from and parallel to the bight portion. The support unit further includes a pair of bight portion clevis mounting members on the bight portion and another pair of brace member clevis mounting members on the brace member pivotally attached to the lift arm and the lift arm actuator, respectively.

Snowplow quick mount lift assembly

An improved blade for a snow plow is provided. The blade includes an inwardly curved, polyethylene moldboard which is secured in a prestressed and arcuate relationship to a structural frame. The frame includes inwardly curved, vertically extending, transversely spaced brace members and a defined space of predetermined shape exists between the moldboard and the braces for improved snow removal by the blade.
