ABSTRACT:
An agricultural plough has a longitudinally extending support member having a forward portion to be attached to a vehicle to thereby enable the apparatus to be towed by the vehicle. A pair of axles extend laterally from opposite longitudinal sides of the support member and provide a pair of laterally extending rotational axes. The axes are on opposite sides of the support member at acute angles longitudinally so as to extend rearwardly, the acute angles being 8 to 10 degrees to a plane extending normal to the support member to diverge rearwardly. Plough discs are supported on the axles to rotate about the rotational axes, with the discs and axles being configured so that the discs converge rearwardly and downward. The discs are displaced rearwardly from the forward portion. A wheel is attached to the support member and rotatable about an axis generally transverse of the support member, the wheel being rearward of the axles, whereby the discs are urged into soil and the wheel is urged into contact with a soil surface rearwardly of the discs so that upon forward movement of the vehicle, the discs form respective grooves and a ridge between the grooves, with the ridge being engaged by the wheel to urge the soil to cover seeds located in the grooves.
