ABSTRACT:
The invention is a plant lifting apparatus of the opposed belt type that can be quickly adjusted in the field to accommodate different plant row spacings. The lifting belts are carried on individual supporting frames. These, in turn, are pivotally mounted at their proximal ends to a subframe member. The distal plant receiving ends of the supporting frames are bridged by spreading means which vary the spacing between adjacent pairs of lifting belts. Preferably the outer belt supporting frames are adjusted separately. The inner pairs are bridged by toggles, turnbuckles or similar means that control their spacing within the limits set by the outer supporting frames.
