On our TERRASEM universal seed drill combinations, soil preparation is taken care of by a two-row disc harrow with plain or scalloped discs.
The maintenance-free, rubber-mounted 510 mm diameter discs loosen and move the soil across the entire working width. Discs at +15 ° in the direction of travel and +7 ° vertical angle for reliable soil penetration to create an optimum seedbed with fine-structured soil at seed slot level. Large volumes of harvest residues are mixed with the soil and at the same time the threat of weeds is reduced.
The new configuration of the tillage tools ensures that the machine works one hundred percent in a straight line. The disc harrow as well as the fertiliser coulters (FERTILIZER machine) and seed coulters are mounted in an X configuration.
A central additional WAVE DISC in the rear section of the discs guarantees full-surface movement.
Further advantages:
Infinitely-variable hydraulic depth adjustment – and the first row of discs can be adjusted mechanically, independently of the second row
Spring-loaded edging boards on both sides ensure a uniform surface finish.
The special twin-race taper bearings have been adopted from the construction machinery industry. Ruggedness and reliability are guaranteed as a result and shock loads are absorbed effortlessly.
The sealed, twin-race taper bearings are maintenance-free.
A labyrinth seal provides the best protection for the bearing.
A metal cover encapsulates the labyrinth seal for additional protection.
Proven over many years in the field, the maintenance-free
40 mm-thick rubber mounting elements
The clamping brackets are mounted on a thick walled box section frame.
Four rubber elements provide a high level of tension to ensure the discs penetrate the soil reliably.
The optional pairs of discs behind the tractor wheels are depth adjustable.
These intensively remove heavily compacted wheel marks to create a uniformly level surface.
It's easy to set the working depth
Overload protection provided
Lifted simultaneously with the disc harrow at the headland
