Soil working apparatus

A soil working apparatus for planting seeds, the apparatus having a sub-unit including at least one rotatable soil working means for disturbing soil in the direction of travel of said apparatus, said at least one rotatable soil working means being oriented for obliquely passing through and beneath the surface of the soil, a sub assembly including a mounting beam mounted for rotation within said sub-unit having at least one oblique axle mounting for receiving an axle of said at least one rotatable soil working means, said axle extending into said mounting beam at an angle offset from the direction of rotation of the longitudinal axis of the mounting beam, and at least one press wheel positioned beside and at least partially behind each of said at least one rotatable soil working means for pressing down the disturbed soil back over any planted seeds, each said at least one press wheel corresponding to at least one of said at least one rotatable soil working means whereby rotation of said oblique axle mounting beam within said sub-unit changes the orientation of said soil working means relative to its respective press wheel and wherein the axis of rotation of said at least one rotatable soil working means is oblique to the axis of rotation of the corresponding press wheel.
