ABSTRACT:
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.
