(under subclass 439) Apparatus in which (1) the struts extend between the earth working device and a wheeled trailer adapted to be drawn by a propelling means or (2) the struts extend between different parts of the earth working device.
(1) Note. The earth working device in part (2) of the definition is an implement which is adapted to be attached to a propelling means such as a tractor, in the field or as a substantially complete unit.
(2) Note. In the ordinary mast-type hitch the struts extend between a tractor and an implement, pivot means for the struts are assembled on or built into the tractor at the factory, the struts remain associated with the tractor in the field and an implement is attached to the struts in the field. This definition is intended to exclude this arrangement but include an arrangement whereby a tractor not equipped with pivot means for a mast-type hitch at the factory is associated with an implement which itself includes the mast-type hitch, or whereby the tractor is converted to use such an implement by securing an attachment to the tractor which includes struts for cooperating with the earth working element (the attachment and the earth working element being considered the implement for purposes of this definition).

248, for an apparatus convertible from one type of hitch to another.
463, for a lift actuator and tool which form a removable unit carried on a wheeled frame.
