ABSTRACT:
An improved row crop cultivator for use in minimum tillage applications is described. A plurality of ganged cultivating units are mounted on a tool bar adapted to be towed behind a tractor vehicle. Each cultivating unit comprises a frame which is supported on a pair of spaced-apart gauge wheels. Also mounted on the frame for rotation within the gap between the gauge wheels is a disk-shaped coulter blade which is configured to cut through crop residue and weed debris as the material being cut is held against the ground surface by the gauge wheels. This arrangement tends to prevent improper cutting known as "hair-pinning". Trailing directly behind the coulter blade is a middleworker comprising a narrow width shank depending from the frame and having a weld point on its lower leading edge and wing-like share blades flaring rearwardly and outwardly at a predetermined angle from the lower end of the shank. The middleworker design reduces the tendency for slabs of earth to be thrown onto and thereby damaging growing row crops.
