A post-harvest tillage pass can be critical to achieving a better seedbed in the spring and setting the foundation of operation performance throughout the year. Give your crop the best chance to succeed while reducing risks at the same time.

The Wil-Rich 483 Chisel Pro incorporates heavy residue and breaks up compaction while creating a smooth field finish. It accomplishes a wide range of tillage objectives in one pass, making the Chisel Pro an ideal post-harvest tool on the path to creating the ideal seedbed.

The Wil-Rich 483 Chisel Pro contains two rows of serrated disc blades to cut and size residue into smaller pieces, so it can break down faster. The concave shape of the discs is designed to thoroughly mix the residue with the soil, helping to speed up the decomposition process even more. The double-mounted discs are 61 cm (24 inches) in diameter with 38.1 cm (15-inch) spacing. The second rank of blades is offset, resulting in an effective blade spacing of 19 cm (7.5 in). This configuration provides consistent tillage across the width of the implement.

Behind the serrated disc blades are four ranks of chisel shanks. These help mix and loosen soil while breaking up compaction layers up to 25.4 cm (10 in) deep. To minimize plugging concerns in heavy residue, the shanks are spaced 152.4 cm (60 in) apart, providing excellent flow between them. Each of the four ranks is offset for an effective shank spacing of only 38.1 cm (15 in). This design results in a more ideal field finish than disc rippers with wider shank spacing.

This finishing option includes a 3-bar coil tine harrow and hydraulically adjustable rolling baskets. The combination of a harrow and rolling basket is ideal for distributing residue, breaking up clods, and creating a level field finish. The angle of the harrows can be adjusted according to conditions. Operators can also adjust the basket down pressure from the cab to achieve the desired field finish. The baskets can be completely lifted off the ground in wet conditions or when not needed.

The 3- or 4-bar tubular harrow features five adjustments for tooth angle. These adjustments allow the user to set the harrow's aggressiveness according to ground conditions and the amount of residue on the soil surface. The tines measure 16 mm (5/8 in) in diameter, are 66 cm (26 inches) long, with a spacing of 30.5 cm (12 inches) between each tine.
