Abstract
A snow groomer tow frame alignment device which automatically centers the implement in line with the vehicle without the visual attention of the vehicle operator. The device utilizes a pair of inductive proximity switches and a corresponding metallic shield disposed around a frame stem pivot, switching in response to misalignment, initiating circuits directing a fluid control valve to actuate to provide fluid to alignment restoring cylinder and ram assemblies.
