Abstract
The harrow comprises a frame (1), for attachment to the trailer, to which is pivoted a ground support wheel assembly (2) spring mounted by an assembly comprising adjustable compression spring (26). An adjustable stop (20b) is provided to limit the highest position from the ground the support wheel assembly can occupy whereby the depth of penetration of the tines (9, 10) can be accurately controlled. The lowest position is determined by engagement of pin (23) and bracket (18). <IMAGE>
