Features

The Strength is in the Gang

Gang Design

The 8315 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.

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 8215/8315 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 PEER® TILLXTREME™ maintenance-free 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 8315 – 37’ model.

Heavy-Duty Walking Beams

Standard on all 8315 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.

  • Wide Spacing: Wide, 10” front and rear gang 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, 9” front and 10" rear spacing offers more aggressive residue cutting and leaves a smooth seedbed, ready to plant.

24/7® Leveling Systems

Increase yield potential through better seedbed condition and increase productivity with non-stop farming. KUHN Krause disc harrows can be equipped with the following 24/7® leveling systems:

  • 24/7® 3-Row Coil Tine Harrow: Featuring a parallel link leveling system for superior residue flow and even distribution, the coil tine harrow offers an increase in yield potential and improved residue management even in high residue conditions. With 16” long tines, 7/16” diameter, the 24/7 Coil Tine Harrow ensures smoother residue distribution and better chemical incorporation.
  • 3-Bar Spike Harrow: For excellent clod sizing in low to moderate residue conditions, the 3-bar spike harrow is an efficient way to create a level seedbed. Rugged ¾” x 10” square spikes provide long-lasting leveling.
  • 24/7® Soil Conditioning Reel: For maximum clod sizing, leveling and soil firming the 24/7 soil conditioning reel is your choice. Choose the round, spiral rods for loamy soils or flat, spiral blades for high clay soils. A float setting widens the tillage/weather window when operating in wet soil conditions.
