Description

ABSTRACT:
An implement has soil working members mounted in a row that extends transverse to the direction of travel. Each member includes a horizontal support secured to an upwardly extending shaft that is driven and a soil working tool at each opposite end of the support. Each tool is freely rotatable about an upwardly extending stub shaft and has two downwardly extending tines. The two tines have respective arms of unequal lengths mounted on a hub that is journalled on the stub shaft and the tines are angled to trail with respect to the direction of driven rotation. This results in the arms being orientated in radial alignment from the soil working member's axis of rotation and the longer arm extending between that axis and the corresponding stub shaft.
