The KUHN Krause Class I – Seedbed Finishing 7305 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 7305 disc harrows offer tillage versatility to the owners of 100 to 300 horsepower tractors. Choose from rock-flex or rigid bearing arms pending on the soil conditions you have on your farm and between wide or narrow blade spacing to give your field the level of finish you’re looking for.

The Strength is in the Gang

Gang Design

7305 tandem disc harrows feature 22” diameter blades with 17-degree front and rear gang angles. The 17-degree gang angles give this machine unmatched performance for residue sizing, soil mixing, herbicide incorporation and field finish while reducing draft and compaction. 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 7305 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.

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.

Rigid Scrapers

KUHN Krause 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.

Bearing Arms

Rigid Bearing Arm: Rigid bearing arms provide a cost-effective solution in non-rocky conditions offering consistent depth with limited lateral movement. Rigid bearing arms feature flange-style PEER^® TILLXTREME™ maintenance-free bearings.
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.

Depth Control

Single Location Remote 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.

Wing Wheels

Wing wheels feature a forward action rotating close to the front gangs for precise depth control and reduced gouging in terraced or rolling conditions. This KUHN Krause design advantage limits the need for optional front gauge wheels.

Walking Tandem Wheels

Walking tandem wheels allow for consistent working depth on rough ground and more stable road transport.

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, 7 3/4”, spacing offers more aggressive residue cutting and leaves a smooth seedbed, ready to plant.

Equipment

Side-to-Side Leveling

Side-to-side leveling is easily fine-tuned with simple eye-bolt adjustments - one on each wing.

Fore-Aft Leveling

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

Rear Hitch

Rear trail hitch is available for machines without the 3-bar harrow. The trail hitch has a 1,000 lb. vertical load and 10,000 lb. towing capacity.

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.
