The cultivator comprises a mount and at least one soil working tool supported for movement through the soil. The tool has an elongate blade arranged to extend downwards and at an acute angle to the vertical. The blade has a leading edge bevelled to lift soil over the blade during passage through the soil. - The tool has at the trailing edge of the blade, a movable extension which is adjustable between a position directly behind the trailing edge and a position projecting upwardly from the trailing edge. In the latter position, the extension increases the lifting action on soil passing over the blade.
