2025 Kuhn 8220 Series 22N

2025 Kuhn 8220 Series 22N

Designed for all-purpose operation in a variety of soil and residue conditions. Working widths range from 18’10” to 44’3”.

The KUHN Krause Class II, all-purpose 8220 tandem disc harrows provide all-purpose operation in a variety of soil and residue conditions. Heavier main and wing frame components combined with improved weld joint construction increase strength and reliability. New spring adjustable scraper assemblies provide aggressive and positive cleaning action in a variety of field conditions.

With a variety of Residue Razor™ disc blades, and wide or narrow spacing, producers can configure the 8220 tandem disc harrow to match their residue and soil conditions for optimum performance. Choose a 24/7® leveling system for a reliable seedbed finish.

Features may include:

Gang Design

With a choice of 22’’ or 24’’ diameter, 6 gauge or ¼’’ thick Residue Razor™ disc blades on 8’’ or 9-1/8’’ spacing, the 8220 disc harrow can be configured for optimum performance in a variety of residue and soil conditions. The 20-degree front and 19-degree rear gang angle provide consistent residue cutting and mixing. Heavy-duty 6’’ ductile iron spools, rock-flex bearing arms and heavy-duty PEER® TILLXTREME™ maintenance-free bearings offer the strength and endurance that sets the 8220 above the competitors.

All KUHN Krause tandem disc harrows are available with Residue Razor disc blades made from Ingersoll's PURE™ steel optimizing strength to withstand stress, fractures, and to provide flexibility in rock conditions. Residue Razor discs have an exceptionally sharp edge, five times sharper than conventional blades. Rollable Disc Blades are also available which allow blades to be re-sharpened for extended residue cutting and soil penetration performance.

KUHN Krause heavy-cast spools multiply the strength of the disc gang. Spools are line-bored for an exact fit on the tie rod and precision faced to perfectly match the blade surface. A larger bell on the concave end and a smaller bell on the convex end provide an overlap fit against the blades, supporting the blade more positively without creating a stress line.

The KUHN Krause Quad-Fold™ design features a rigid center section with a folding inner and outer wing. The outer wing hydraulically locks to the inner wing in field use to create a 3-section disc with even weight distribution. Quad-Fold 41- and 44-foot models are a full 5-section design. Quad-Fold is available on 8220 – 36’ to 44’ models.

Standard on all 8220 disc harrows, heavy-duty walking beams allow for consistent working depth on rough ground and more stable road transport. Walking beams have slip-in spindles and heavy-duty hubs.

Choose wide or narrow spacing to better match the needs of your operation.

• Wide Spacing: Wide, 9 1/8”, spacing offers more aggressive residue mixing and leaves a course finish to resist wind erosion and aid in the drying of soil.

• Narrow Spacing: Narrow, 8”, spacing offers more aggressive residue cutting and leaves a smooth seedbed, ready to plant.

Increase yield potential through better seedbed condition and increase productivity with non-stop farming.
