A soil cultivating machine has a row of cultivating members which are mechanically driven and rotatable about upwardly extending axes positioned on a transverse row. An elongated, transverse hollow frame portion supports at least twenty shafts of the cultivating members and the shafts are preferably about 15 cms apart. Transmission parts of the members are housed in the frame portion. The frame portion comprises two U-shaped parts clamped together at longitudinal edges between which edges gasket material and spacer members hold the longitudinal edges at a predetermined distance from one another. The cultivating members can each have a single downwardly extending tine with an upper flat fastening portion that extends substantially transversely of the rotary axis of the cultivating member, and a lower operative portion that joins the flat fastening portion eccentrically of the rotary axis of the cultivating member. At each side of the frame portion a supporting skid is adjustably connected to plates which close the hollow frame portion.
