Terradisc


The TERRADISC compact disc harrow is designed specifically for stubble cultivation and seedbed preparation. The compact design and aggressive disc angle ensure reliable penetration and excellent mixing in of harvest residues.

Adjustable headstock

TERRADISC 3001 / TERRADISC 3501 / TERRADISC 4001

Tractors with up to 190 hp have a huge range of hitch geometries. The range of mounting options offered by the headstock ensures excellent ground penetration and sufficient transport height. Three lower linkage mounting heights with clevis-type mounting lugs are offered as standard. The headstock angle can be adjusted and with three top linkage positions optimum adaptation to any tractor is guaranteed.

Heavy duty frame

The compact frame is a trademark of the mounted TERRADISC harrow. Unique open frame design provides a perfect view of both disc gangs from the drivers seat.

  • The first gang of discs is very close to the tractor for a very favourable centre of gravity.
  • Compact, short design guarantees smooth and stable operation of the implement.

TWIN ARM – the heart of the machine

Two solid forged carrier arms are welded to a very wide clamping bracket. This ensures that the discs always retain their position and angle. Even in heavy soil it is impossible for them to deviate to the side hard wheel tracks are broken up consistently.

The rugged scalloped discs made of special heat-treated steel have a diameter of 22.83" / 580 mm. Eight discs per metre of working width equate to a spacing of just 4.92" / 125 mm. The optimised interplay of ground penetration angle and mounting angle ensure perfect performance. The offset configuration of the aggressive discs mixes harvest residues effectively into the soil.

NON STOP stone protection

Proven over many years in the field, the maintenance-free NON STOP trip protection system features 1.57" / 40 mm thick rubber elements. The clamping brackets are mounted on a thick-walled box section frame. Four rubber elements between each wide clamping bracket and the box section provide the discs with high penetration power.

  • The sealed, twin-race tapered bearings are completely maintenance free.
  • A labyrinth seal provides perfect protection for the bearing.
  • A metal cover encapsulates the labyrinth seal for additional security.
  • The bearings are fitted to the disc carrier arm by a stub axle.
  • The nuts are protected by caps mounted on the same stub axle.

Generous inter-disc clearance

  • Plenty of space between discs and carrier arms.
  • The carrier arms are angled facing the direction of rotation so that there is no risk of stones or harvest trash becoming lodged between the disc and arm.
  • A large clearance between the disc and clamping bracket means large quantities of organic matter can easily pass through.

Adjustable outer discs

On the left and right the outermost concave discs are depth adjustable. This means you achieve perfect merging of passes.

Levelling harrow

The optional spring steel levelling tines deflect the flow of soil to the rear roller, crumbling and levelling the ejected mixture of trash and soil. The height of the levelling tines, which are 0.55" / 14 mm thick and feature tangential geometry, is adjusted when the position of the rear roller is changed.

  • The basic height and angle settings are preset using a pin-in-hole matrix.
  • The position of the tines changes in accordance with the working depth. The deeper the setting the easier the flow of material to the rear.

Edging boards as standard

For a uniform surface finish, adjustable edging boards are provided on both sides as standard equipment.
