A large wing fold rotary cutter is front mounted on (mounted at the leading end of) a tractor and pushed rather than pulled. The cutter has a centre cutter section (16), two wing cutter sections(18) mounted on opposite sides of the centre and wing sections and castor wheels (39, 48) for supporting one end of the centre section. The cutter is connected to leading end of the tractor by a hitch (64) is connected to the trailing end of the centre section. The hitch (64) prevents yaw and roll of the cutter relative to the tractor. The transport castor wheels (39) are mounted on the leading end of the centre section by a wheel suspension (42) including a transverse walking beam (44) thus allowing the transport wheels to move vertically on the centre section. A linkage system (68) couples the hitch (64) and the wheel suspension (42) for lowering and raising the transport wheels relative to the centre section in response to respective raising and lowering of the trailing end of the centre section with the hitch. By attaching the cutter to the leading end of the tractor, the operator needs only to look forward in order to operate the tractor and the rotary cutter. By using folding wings the rotary cutter is capable of a wide cutting width white still folding to a transport width of as little as 2.5 meters. By using a three section deck the rotary cutter is capable of following uneven ground more closely than a single deck rotary cutter of a similar width. The cutter may use relatively large diameter blade sets (larger than 1.2 meters diameter) and an independent drive to each individual blade set, so that the machine is capable of cutting heavier material that would be typical of the rotary cutter class rather than the finishing mower class.
