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
7400 Series discs.

Five inch wide rigid scrapers
Five inch wide 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. The wide design keeps wet soil from building up on the blades. You can adjust each scraper individually or move the entire gang of scrapers at the same time.

Massive 1 1/2" x 15" hinge bolts
Even the wing fold hinges on the 7400 Series discs display the Krause commitment to quality. Massive 1 1/2" x 15" hinge bolts distribute folding forces over a wide area... not concentrating them in a narrow hinge like some competitive designs.
