Machine for cultivating the space between wheels intended for weed control in vegetable cultivation. The machine for cultivating the space between wheels comprises a frame 1, which must be coupled to a tractor and which comprises a secondary frame, that is to be moved by means of a hydraulic control. Fixed frames 8 for devices for mechanical and heat treatment, intended for cultivation of space between the wheels, have been fixed to the secondary frame 2. The fixed frames 8 can be located on the secondary frame 2, which is to be moved according to the space between wheels. The machine for cultivating space between wheels comprises a heat source 13 operating on solid fuel, which is intended for heat treatment. The heat source 13 comprises a firebox 16, around which there is a jacket 17. Combustion gases mixed with secondary air are led through openings 19 in the end 18 of the jacket. The mixture of combustion gases and air is delivered to the heat treatment mouthpiece 24 by a blower 20 via a distributor 22 and a piping system 23. The machine for cultivating space between wheels comprises a rotary cultivating device 25, which must be fixed to the secondary frame and which is intended for mechanical weed control. The cultivating device 25 comprises a cutter head 27 functioning with a separate motor 26. On the cutter head between flanges 28, there are shafts 29, on which cultivating blades 31 have been fixed with articulated casings 30, so that the blades turn under centrifugal force towards the radius of the cutter head. <IMAGE>
