The KUHN Class I – Seedbed Finishing 8100 tandem disc harrows offer the quality and reliability you need for proper placement of your high value seeds. These machines deliver excellent residue cutting and seedbed preparation. Proper seed placement is critical to maximize yield potential. These discs provide a good weight-to-blade ratio to ensure consistent operation in a variety of soil conditions.

The 8100 disc harrow offers tillage versatility to the owners of 60 to 145 horsepower tractors. With features like rock-flex bearing arms, 0.56 m Residue Razor disc blades with narrow or wide spacing, adjustable gang angle, dual wheels and a built-in rear hitch, the 8100 disc harrow allows operators to perform seedbed preparation and residue management with a variety of options.

The Strength is in the Gang

Gangs_8100.png

Gang Design and Residue Razor™ Disc Blades

8100 tandem disc harrow gangs feature 22” diameter Residue Razor™ blades, mounted on Rock-Flex bearing arms, with SuperSeal regreasable bearings. The front gang angle is adjustable from 15 to 21 degrees, and the rear gang angle is adjustable from 12 to 18 degrees. Adjusting the gang angles gives this machine unmatched performance for residue sizing, soil mixing, herbicide incorporation and field finish. Rear gangs feature tapered blades to provide a level pass-to-pass finish. Bolt-on extension spool and furrow filler blades are standard equipment on 8100 discs, so inadvertently hitting an obstacle doesn’t damage the entire gang.

All KUHN 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.

Rigid Scrapers

KUHN rigid scrapers are heat treated and hot formed from the same high carbon steel we use in our disc blades. The result is an extremely strong and efficient scraper that resists wear. You can adjust each scraper individually or move the entire gang of scrapers at the same time. 3 ½" wide scrapers are standard equipment. Double scrapers at bearing arms are optional.

Spools

KUHN 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.

Wide or Narrow Spacing

Wide or Narrow Spacing

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.
