Abstract: An implement hitch assembly serves to aggregate two machines. The machines are echeloned in the working position or in tandem in a transport position when moving from one field to another. The hitch includes a transverse draw bar, connected to a tractor. On the transverse draw bar, provision is made for a pull rod of a front farm machine, which is mounted thereon by a carriage. The hydraulic drive installed on the transverse draw bar is intended for moving the carriage along the transverse draw bar. A lever pivotably connected to the pull rod of the front farm machine carries an arcuate beam coupled therewith at the front end thereof by a pivot. The rear end of the arcuate beam rests on a support wheel with a suspension. On the vertical axis of the suspension there is mounted a clevis of a rear farm machine. The hydraulic drive connected with the pull rod of the front farm machine moves the latter along as it transfers both machines to one of the positions hereinabove identified.
