7300 Series "Flex-Wing" Tandem Disc Harrow

3-Section,
18 - 27 ft.

Model 7300 - 34W (34') shown

Standard Equipment
Single location remote depth control
Single location 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. New sight gauge makes depth setting more convenient. Handy transport lock is located right next to the depth controls.

Rear gangs feature tapered blades
Rear gangs feature tapered blades to eliminate
ridging. Bolt-on extension spool and furrow
filler blade are standard equipment on
7300 Series discs.

Rigid Scrapers
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 1/2" wide scrapers are standard equipment. A 5" wide scraper is optional for use in wetter soils.

Massive, rigid bearing standardsMassive, rigid bearing standards feature a narrow, smooth profile to let residue pass through. The strength, durability and lower cost of this design make it an excellent choice for fields where rock is not a concern. Wing fold hinges on the 7300 Series feature 1 1/2" x 15" hinge bolts to distribute folding forces over a wide area... just another example of Krause's commitment to quality.
