A mowing machine is connectable to a tractor's lifting hitch and power take-off. A row of rotors is mounted along the length of a laterally extending support that includes an elongated supporting plate pivoted to the main frame. The supporting plate can be an integral plate profiled to have an upwardly extending front and a channel section. Each rotor includes an upwardly extending shaft splined to a gear positioned beneath a hub and a cutting member. The drive to each rotor can be meshed gear wheels readily removable and replaceable as a unit or an elongated driving shaft housed in the channel section. The unit enclosed gear box can house all of the gear wheels or individual gear boxes can be fixed to the supporting plate. The cutting members can be then one or two blades or wires per rotor that are freely pivotable about upwardly extending axes located a substantial distance from the respective shafts which define the axes of rotation of the rotors. The rotors having one cutting member can be balanced by weights on the hubs so that a high rate of rotor rotation is achieved, the cutting members of neighboring rotors positioned to overlap one another. Neighboring rotors can be driven in the same or relative opposite directions and quick release fastenings secure the hubs to their respective shafts.
