60' Schulte DHX-600 Disc Harrow
Professional producers require equipment that can manage increased straw and chaff loads post-harvest, increase water penetration, quicken soil warming and promote weed seed germination for a proper pre-seed burn-off operation. DHX-600 does all that with its double row of wavy coulters and five bar heavy harrow. The coulters engage the ground sizing the straw and mixing the chaff within the top layer of soil. The heavy harrow evenly distributes, levels and breaks up residue that is discharged by the coulters. The DHX-600 is the evolution of the heavy harrow, the next level of performance for post harvest and pre-seeding.

The DHX’s two rows of 18” eight wave coulters on 7.2” spacing followed by five bars of 5/8” x 26” heavy harrow tines allows it to efficiently chop straw, mix residue with the ground all while spreading and leveling.
The coulters are mounted to a four-bolt service free hub and a specially designed flat bar shank. The four-bolt hub includes an Over Cap, a Grasswrap Guard, a V-Seal and a Triple Lip Seal protecting back to back Ball Bearings that will provide years of trouble-free use. The hub is completely rebuild-able to help reduce service costs and down time. The flat bar shank has been designed out of ½” x 4” 6150 spring steel for long life excellent ground following.
The harrow tine coils are designed to get larger towards the outside of the tine to reduce stress during field operation. All harrows are controlled hydraulically for on the go adjustment. The down pressure on the harrow section can be easily adjusted with two large tension springs.
There is a single point depth control for the discs mounted at the rear of the machine. Simply move the threaded crank for fine tuning the disc depth in the field.
The main frame of the DHX is made from 12” x 12” 3/8” thick tubing making the machine robust and providing the necessary weight to make the disks extremely effective. The wing frames have been designed to carry almost an additional 3,000 lbs of water which adds an extra 30 lbs force to each disk for increased penetration if needed.
The wing knuckle is made from 2” plate and uses 2.5” diameter Nitrided pins and MLG fiber bushings making it service free.
No more Cables! The DHX incorporates a hydraulic lock for the wing tension links. Cables stretch and can catch on things and inadvertently open the lock during operation. The new hydraulic actuated lock eliminates all those issues and incorporates a lock pin to ensure inadvertent actuation of the cylinder during field operation.
