ABSTRACT:
A cultivating implement has a row of soil working members journalled along the length of an elongated frame portion. The frame portion extends transverse to the direction of implement travel and a support beam with further soil working members is positioned at the rear of the frame portion. The support beam is interconnected to the frame portion by arms and at least one, preferably two, pivot points on each arm enable adjustments of the level of the support beam with the further soil working members to be effected. One pivot point is at the rear portion of each arm and includes locking and pivot bolts. A second pivot point, again including locking and pivot bolts, connects the forward portion of each arm to the frame portion.
