7300 Series "Flex Wing" Tandem Disc Harrow
Model 7300-34W (34') shown

Krause raises the bar... again. The new 7300 Series Flex-Wing Tandem Disc Harrows are destined to be the benchmark for the highly versatile, medium weight class disc, much like their popular predecessors, the 3950 and 3990 Series.

In sizes from 18' to 34', the 7300's offer a wide range of standard and optional equipment choices to match the specific tillage needs of your farm. With a weight per foot of cut at 430 lbs. maximum, the 7300 is tops in it's class. New option choices include walking tandem wheels and hydraulic leveling... productive additions with precision depth control and more stable discing performance the benefit.

Choose from standard models with rigid bearing arms or Krause's popular and rugged, Rock-Flex models with flexible C-type bearing arms. All 7300's come equipped with 22" diameter disc blades and a choice of 7 3/4" spacing for optimum seedbed finishing, or 9 1/8" spacing for all around performance and optimum penetration in primary work. And just like the highly successful 3950 and 3990 Series which they replace, the 7300 carries on the 17 degree front and rear gang angle. 17 degree gang angles give the 7300 unmatched performance for residue sizing, soil mixing, herbicide incorporation and field finish while reducing draft and compaction. And it accomplishes all these tasks without the negative performance attributes associated with "shallow concavity" blades as used on some competitive brands. You'll find there's al lot more to the 7300 story... read on to find out how this top performer can boost your farm's productivity.

Take a close look at the 7300's frame design... massive 6" x 6" main members impart strength and rigidity. Look across the disc too... you won't find any unsightly wing fold mechanisms to block your view in the field... clean, uncomplicated, strong... all words that describe the new 7300. One-piece center frame rocker shaft eliminates the need for linkages between rockers. Of course Krause's overlapping gang design provides a level field finish, the "trademark" of a Krause disc. 7300 one-piece center frame rocker shaft
The 7300's self-leveling hitch features an adjustable leveling link for fore to aft leveling changes. The self-leveling mechanism is spring cushioned for protection . With the combination clevis (see set), you'll always have the correct hitch. With the optional hydraulic leveling you can fine tune front to rear leveling from the tractor cab.

Wing wheels feature a forward action that rotate close to the front gangs for precise depth control and reduced gouging in terraced or rolling conditions. This Krause design advantage limits the need for optional front gauge wheels that are necessary on other bands with wheel placement much farther from the front gang. The model shown is equipped with optional walking tandems on the center and wings. Wing wheels with forward action

Reliability and Performance Features
Walking TandemsWalking tandems are optional on the center and wings of 7300 Series disc harrows. Walking tandems provide more precise depth control and more stable discing... especially at higher field speeds. Compare the Krause design of mounting the massive "L" shaped wing rocker shafts to both the inner and outer front to rear frame beams, to competitive models that mount only from the outer beam. The Krause design easily handles the stresses created by out of ground field turns.
No plastic components in our rocker pivotsTrue to Krause's commitment to long term durability, you'll find no plastic components in our rocker pivots... only case hardened steel pins with replaceable steel bushings. Krause's lift system minimizes the amount of torque through the pivot points with the hydraulic cylinders acting directly on the wheel arms. With an occasional greasing you'll never need to worry about replacing them!
Simple eye-bolt adjustments for side to side levelingSide to side leveling is easily fine-tuned with simple eyebolt adjustments - one on each wing.
