The KUHN Krause Class III 8320 tandem disc harrows provide primary tillage operation utilizing greater gang angles and a weight increase over Class II all purpose disc harrows. 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.

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 8320 tandem disc harrow to match their residue and soil conditions for optimum performance. Choose a 24/7® leveling system for a reliable seedbed finish.

The Strength is in the Gang

8320 gang.png

Gang Design

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.

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.

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.

Spring Adjust Scrapers

The 5-inch scraper is easily adjusted by simply loosening a single bolt, adjusting for scraper gap if needed and locking in place by tightening the bolt.  The scraper spring provides the tension to move the scraper to the specified location against the face of the disc blade.

Rock-Flex Bearing Arm

Rock-flex bearing arms provide protection from rocky or hard soil conditions and feature PEER® TILLXTREME™ maintenance-free bearings. The bearing arm scraper has adjustability to clean the concave side of each disc blade located at the Rock-Flex bearing arms limiting soil and residue buildup in the bearing hanger area.

The Ultimate in Transportability

8315_Transport01.jpg

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 8320 – 37’ model.

Heavy-Duty Walking Beams

Standard on all 8320 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

8320_WideNarrowSpacing.png

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.

Equipment

8220_8320_GaugeWheel.png

Castering Wing Gauge Wheels

To help pivot with the disc harrow on contours, instead of creating a furrow, the castering gauge wheels are standard on the Quad-Fold™ models and optional on others. The wrenchless adjustment makes setting easier than ever. Unlike rigid gauge wheels, castering wheels pivot on contours, instead of sliding in loose soil.
TractorInterfaceCenter.png

Tractor Interface Center

The tractor interface center prevents hydraulic hoses from binding in turns and adds operator convenience. Includes hose routing chart, color coded hose grips, storage for light hookup and owner’s manual.
8215_8315_SinglePointDepthControl.jpg

Single-Point Remote Depth Control

Single-point remote depth control, conveniently located at the front of the disc, makes it easy to fine-tune depth adjustments. Return to the same depth after each pass or change depth from field to field in a matter of seconds. The sight gauge makes depth setting more convenient.
GuardianHitch.png

Guardian Hitch™

Standard on all Quad-Fold models, the Guardian Hitch guards against stress on the tractor drawbar and implement frame. Lateral drawbar forces are transferred through the hitch pivot where shock load from steering input is dampened by urethane blocks.
HydraulicLeveling.jpg

Fore-Aft Leveling

Optional hydraulic leveling allows for field-to-field, front-to-rear leveling adjustments without leaving the cab.
8215_8315_RearHitch.jpg

Rear Hitch

The optional rear hitch features an extendable tongue allowing one person to easily connect towed implements.
