Standard Equipment |
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 to eliminate
ridging. Bolt-on extension spool and furrow
filler blade are standard equipment on
7400 Series discs.
|
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. |
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. |

terrain. Tires are 20.5" x 8", 6-ply. Easy

Add a Krause 3-Row Tine Harrow for a
finishing touch on your freshly tilled soil. Krause
harrows feature rugged 7/16" diameter tines for
long wear and are 16" long for high residue handling
capabilities. Smoother residue distribution and better
chemical incorporation are excellent reasons to add
a tine harrow to your Krause disc. 
Optional Packer Hitch includes an extendable
sliding tongue for easy hookup. |
