Abstract:
A soil levelling device for an impact roller having at least one compactor mass, the levelling device comprising:coupling means for coupling the levelling device to an impact roller so as to trail the impact roller in use; a support frame connected to the coupling means and including a transverse beam; for each compactor mass of the impact roller, a ground-engaging levelling blade carried by the transverse beam, the levelling blade being arranged to cut soil which has been traversed by the compactor mass and thereby to perform a soil levelling action; and for each levelling blade, a ground-engaging shoe connected to the transverse beam for pivotal movement relative to the transverse beam about an axis transverse to the direction of movement of the impact roller, the shoe having fore and aft portions which lead and trail the levelling blade, whereby the shoe can follow the contour of a surface of the ground to control the depth of cut achieved by the levelling blade.
