If your farming operation calls for a heavy-duty, offset disc harrow, there’s no better choice than the KUHN Krause 5805 offset disc harrow. KUHN Krause offsets are renowned for their rugged dependability and heavy-duty construction. Choose from rock-flex or rigid bearing arms pending on the soil conditions you have on your farm.

YOUR BENEFITS

The Strength is in the Gang

FrontGang_5805

Gang Design and Residue Razor™ Disc Blades

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.

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.

Spring Adjust 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.

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.

The Ultimate in Transportability

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.

Wide or Narrow Spacing

Metric Tires

280/70R15 metric tires have been incorporated into the 5805 for additional weight carrying capacity at lower operating pressures.

EQUIPMENT

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.

Single-Point Hydraulic Depth Control

A single-point, crank-style depth control is located on the left-hand side of the machine providing easy access for the operator. Depth adjustment can be fine-tuned for variable soil conditions. The depth indicator is located on top of the tube for easy viewing.

Adjustable Tongue

A handy 7-setting wrenchless adjustment makes it easy for the operator to set the 5805 for the correct draft.

Rear Hitch

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

Rear 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.

Rear Hitch

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.
