The Strength is in the Gang
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 8210 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 SuperSeal bearings offer the strength and endurance that sets the 8210 above the competitors.
Residue Razor™ Disc Blades
All KUHN Krause tandem disc harrows feature Residue Razor disc blades that are engineered with a unique Boron 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.
Spools
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.
Hi-Clearance Scrapers
The 5-inch hi-clearance rigid scrapers on 8210/8310 tandem disc harrows handle high amounts of residue. The shallow scraper angle and high integral mount improve residue flow and blade-cleaning performance.
Rock-Flex Bearing Arm
Rock-flex bearing arms provide protection from rocky or hard soil conditions. Rock-flex bearing arms feature SupeSeal bearings.
The Ultimate in Transportability
Quad-Fold™ —The Ultimate in Transportability
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 8210 – 36’ to 44’ models.
Heavy-Duty Walking Beams
Standard on all 8210 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.
Wide or Narrow Spacing
Choose wide or narrow spacing to better match the needs of your operation.
