Kuhn 5805 Offset-12R

The Strength is in the Gang

Gang Design

5805 offset disc harrow gangs feature 26” or 28” diameter blades mounted on Rock-Flex or rigid bearing arms and feature PEER® TILLXTREME™ maintenance-free bearings. Gang angles are pin-stop adjustable from 16 to 25 degrees. A ratchet-jack, located on the rear gang, allows side-to-side gang adjustment to fine-tune performance. Front and 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 5805 discs, so inadvertently hitting an obstacle doesn’t damage the entire gang.

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.

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.

Rugged Scrapers

The 6 ½”, paddle-type, flat-blade scrapers are mounted individually on a scraper bar. The scrapers and bar may be adjusted for varying soil conditions.

Frame Design

Massive main frame beams are 6’ x 8’ x 3/8” structural steel with gang beams of 4” x 10” material, providing ultimate strength and rigidity.

The massive tongue features a handy “wrenchless” adjustment with seven different settings, making it easy for the operator to set the 5805 for the correct draft. The rocker shaft design utilizes hydraulic cylinders that act directly on each wheel arm, reducing frame stress and torsion.
