A hitch assembly comprising a hitch bar 1 having a hitch 2 for attachment to a tractor at its leading end; a pair of drawbars 4,5, each having one end pivotally connected to the hitch bar 1 so as to be swingable in a substantially horizontal plane between a work position in which it extends laterally to the direction of travel, one on each side of the hitch bar, and with the outer end of one bar 5 extending rearwards further than the outer end of the other drawbar 4, and a transport position in which it trails rearwards of the work position; a support wheel 8,16 attached to the outer end of each drawbar 4,5; a hitch 10,18 on each drawbar for attachment to an implement, the hitch 18 on said one drawbar trailing behind that on said other drawbar in the work position; and a pair of stay-bars 23,24 each having one end pivotally connected to the hitch bar 1 so as to be swingable in a substantially horizontal plane between work and transport positions, each stay bar 23,24 in its work position being connectable by a fastening 27,28 to a respective one of the drawbars 4,5 to hold the drawbar in said work position. A wheel assembly 13 is connected to the outer end of the drawbar 5 by a pivotal connection 14 with a vertical axis about which the wheel assembly 13 can pivot relative to the drawbar 5 in moving the latter from the work to the transport position. The drawbar 4 is held in its transport position by its stay bar 23 with the drawbar 4 trailing rearwards at an angle to the direction of travel.
