Schulte THX-360 / THX-600 TILL 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. THX does all that with its single row of concave discs and five bar heavy harrow.

The concave discs 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 concave discs. The THX is the next level of performance for post harvest and pre-seeding.

The THX’s single row of 20” 10 degree concave discs on 8.5” spacing followed by five bars of 5/8” x 26” heavy harrow tines allow it to efficiently chop straw, mix residue with the ground all while spreading and levelling.

The concave discs are mounted to a four bolt service free hub and a specially designed shank. The rubber torsion shank has been designed for long life and ground following.

There is a single point depth control for the discs mounted at the rear of the machine. Simply move the adjustment along the slide
to set your disc depth.

The harrow tine coils are designed to get larger towards the outside of the tine so as to reduce stress during field operation.

When it comes to the amount of force the harrows are exerting on the ground there are two options: Spring and Electronic
Hydraulic. The Spring adjustment uses two tension springs that can be adjusted to increase or lower the amount of force put onto the harrows. This option only provides down pressure onto the harrows. Both of the Hydraulic options use cylinders mounted onto the harrow arms to adjust either down or up pressure. Up pressure will take weight off the harrows for working in extremely heavy debris or damp conditions. The difference between the Manual and Electronic Hydraulic versions is that the Manual version has a valve on the hitch which you manually use to adjust the up or down pressure on the harrows. The Electronic version allows you to adjust the up or down pressure on the harrows
using a monitor system from the comfort of your cab.


The main frame of the THX 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 cast wing knuckles use 2.5” diameter pins along with spring steel bushings which are greasable to ensure long life.

No more Cables! The THX incorporates a hydraulic lock for the wing tension links. Cables stretch and can catch on things and inadvertently open the lock during operation. The hydraulic actuated lock eliminates all those issues and incorporates a lock pin to prevent inadvertent actuation of the cylinder during field operation
