TERRADISC T Trailed foldable short disc harrows

TWIN ARM

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.

Clever tillage tools

The rugged scalloped discs made of special heat-treated steel have a diameter of 580 mm. Eight discs per metre of working width equate to a spacing of just 12.5 cm. 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.

For an extended service life

The strong rugged discs made of special heat-treated steel have an optimum diameter. The disc diameter of 580 mm and material thickness of 5 mm ensure a long service life. You benefit from extended replacement intervals as a result.

Perfect penetration

• 1. Perfect entry thanks to aggressive disc angle

• 2. Blockage-free operation thanks to large clearances

• 3. Extended service life with tempered and forged parts

• 4. Worked soil – uniform and level finish following consistent movement

• 5. Unworked soil

The best soil movement

A uniform level finish with the best mixing performance meets farmer's and contractor's expectations in the field. To achieve this, PÖTTINGER has optimised the geometry, size, plus both mounting angle and penetration angle of the discs. The result: low draft, perfect penetration, the best tilth and mixing effect, even in dry soil. The high tare weight of the TERRADISC also ensures the dependable performance of this disc harrow.

Generous inter-disc clearance

The best soil movement

Generous inter-disc clearance

Ideal cultivating results are achieved thanks to optimum spacing of the discs.

• Plenty of space between discs and carrier arms.

• The carrier arms are angled facing the direction of rotation so that the risk of stones or harvest trash becoming lodged between the disc and arm is greatly reduced.

• A large clearance between the disc and clamping bracket means large quantities of organic matter can easily pass through.

Maximum uptime and durability

Fast operating speeds and working depths down to 15 cm mean the disc bearings have to withstand considerable stress. That is why PÖTTINGER has implemented high-quality bearings for an extended service life. This guarantees you trouble-free work even in the most difficult operating conditions.

Tough and reliable

The special twin-race taper bearings have been adopted from the construction machinery industry. Ruggedness and reliability are guaranteed as a result and impacts are absorbed effortlessly.

• The sealed, twin-race taper bearings are completely maintenance-free.

• A labyrinth seal provides the best 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 shaft.

NONSTOP protection against stones

NONSTOP protection against stones

40 mm thick rubber elements have provided proven, maintenance-free NONSTOP trip leg action for many years. 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.

Adjustable outer discs

Adjustable outer discs

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

Convenient operation

The rear rollers assume the role of depth control for the disc harrow. Working depth is adjusted hydraulically and quickly without risk to the operator. The weight of the roller is transferred to the disc harrow during operation. Thus ensuring reliable penetration on dry and hard ground.

Convenient adjustment

Setting up for different soil conditions must be quick and straightforward. On the TERRADISC compact disc harrow that's conveniently solved with hydraulic depth adjustment.

• Folding 5 mm-thick swing clips are used to fine-tune depth control.

• The levelling tines are adjusted in unison with the roller mounting arms.

• No complicated manual intervention required – convenience that every tractor driver deserves.

Transport - for rigid disc harrows

folding edging discs

The outer disc pairs are folded upwards hydraulically for transport on the road. The edging board is simply pushed inwards for transport widths of 3.0 m, 3.50 m and 4.0 m.

• The TERRADISC 3501 can be transported on the road unaccompanied in situations where laws permit a width of 11.84' / 3.50 m.

• That offers up to 17 % higher output compared to a 9.84' / 3.0 m implement.

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 14 mm thick and feature tangential geometry, is adjusted when the position of the rear roller is changed.

• The main height and angle settings are preset using a pin-in-hole matrix.

• The position of the levelling 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

Edging boards as standard

For a uniform surface finish, adjustable edging boards are provided on both sides as standard equipment. This ensures a neat interface between passes.
