ABSTRACT:
A hydraulic system for an attachment for a tractor is disclosed. The hitch has a frame having a top member and a bottom member. The top and bottom members are joined together by a pair of side members forming a structure with an orifice. Each of the top and bottom members are hollow in a cross section, as are each of the side members so that a fluid contained in the members can flow from one member to another.
