Abstract
A reversible wing plow including a hitch, a moldboard and a moldboard shifting mechanism. The hitch is coupleable to the rear of a prime mover. The moldboard is operably coupled to the hitch proximate an inboard end and rotatable about a first horizontal axis that extends outwardly from the hitch generally parallel to a direction of forward movement of the prime mover. The moldboard shifting mechanism includes first and second linear actuators, both of which are coupled to the hitch at one end and coupled to opposing sides of a rotation crank plate on the other end. The crank plate is further operably coupled to the moldboard, whereby the moldboard is rotatably shiftable to the driver or passenger side of the prime mover, or to a vertically oriented transport position.
