Cultivating machine

A cultivating machine includes a tool carrying frame 10 on which fixed cultivating tools 13 are mounted and a rotor carrying frame 11 on which a cultivating rotor 20 is mounted. The tool carrying frame is in advance of the rotor carrying frame and is attachable to the three point linkage of a tractor by which the height of the frame 10 is selected. The rotor carrying frame 11 is supported for movement over the ground during operation by a rear roller 30 and by wheels 35 in advance of both frames. The two frames 10 and 11 are coupled together in a manner which allows the frames to move up and down relative to one another and such movement enables the rotor and the fixed tools to find their most effective position in relation to the ground surface.
