ABSTRACT:
A sand fighter is drawn through an agricultural field by a tractor. The sand fighter has five sections. The outer or distal sections are folded manually. The inner or proximal sections are folded hydraulically. The center or medial section is connected to the power lift of the tractor so the entire sand fighter may be raised and lowered and drafted through the field.
