The Kuhn Krause Tandem Disc Harrow 8320 is designed to provide primary tillage operation where maximum soil penetration and residue mixing is required. it features working widths range from 19’10” to 37’3”. Residue Razor™ disc blades, aggressive gang angles and a significant weight increase over all-purpose tandem disc harrows means the 8320 delivers better residue cutting and mixing. With a wide or narrow spacing, producers can configure the Tandem Disc Harrow 8320 to match their residue and soil conditions for optimum performance. Choose a 24/7® leveling system for a reliable seedbed finish.
Residue Razor™ Disc Blades
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.
The 8320 tandem disc harrow offers a choice between 24” or 26” diameter, ¼” thick Residue Razor™ disc blades spaced 9” or 10” apart on the front gang and 10” apart on the rear gang. Heavy-duty 7” diameter ductile iron spools multiply the strength of the gang. The 22-degree gang angle on the front and 19-degree gang angle on the rear allow for optimum residue cutting and mixing in primary tillage conditions.
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.
