Abstract
A plow support assembly provides support of a plow assembly when the plow assembly is disconnected from a vehicle. The support assembly includes a support foot and is operable to move the support foot to a lowered, support position whereby the support foot engages the ground or support surface. The support assembly includes a control device which is operable to limit the downward movement of the support foot in response to a signal indicative of the support foot engaging the support surface, such that movement of the support foot is stopped once the support foot contacts a support surface or ground. The signal may be provided by a switch which is operable to communicate the signal in response to detection of a threshold position of the support foot, engagement of the support foot with the support surface, or a threshold hydraulic fluid pressure within the actuator, respectively.
