An earth working apparatus and method are disclosed. The apparatus includes a primary rotatable drum (30) having a number of picks (38) mounted on it, and a secondary rotatable drum (32) having a number of paddles (56) mounted on it. The drums are mounted adjacent one another with their axes substantially parallel and are rotatable both in the same direction or in opposite directions. The picks (38) of the primary drum cut the soil in use, while the paddles (56) pass between the picks (38) and help to mix the soil and clean the primary drum (30). The mixed soil is then re-deposited. The apparatus can be mounted on a traction unit (10) to drive the apparatus over land to be worked.
