Abstract
Abstract The mounting unit is adapted for use with a tractor that has a horizontally swingable drawbar and a support therefor and comprises a frame assembly having spaced interconnected horizontal plate members for receiving the drawbar therebetween when the forward section of the frame assembly is positioned within a guideway formed in the drawbar support. With the drawbar held against horizontal and vertical movement relative to the frame assembly, a pull behind tractor mower is connectible to the mounting unit by mower supported releasable clamps that are attachable to transverse pivot means carried at the rear end of the mounting unit.
