Pottinger appears to have caught the 'bigger is better' bug, when it comes to cultivation equipment.

The latest additions to its Terradisc range extend the available working widths up to 8m and 10m, from a previous maximum of 6m.

Designed primarily for the cultivation of stubble and incorporation of trash, the new trailed models have a working depth of between 5cm and 15cm.

Pottinger claims that it is not just the width that accounts for a high work-rate. It says: "Working speeds of up to 18kph ensure an enormous output for the new Terradisc. The uniform, shallow working depth and optimum packing effect produce a perfect seedbed."

The key to efficient incorporation and mixing of harvest residues is, according to Pottinger, the "optimisation of the geometry, size, mounting angle and penetration angle of the discs".

To preserve this geometry, the company notes that the "two solid forged carrier arms are welded to a very wide clamping bracket". This apparently ensures that the discs always retain their position and angle.

When turning at the headlands, the weight of the discs and frames is transferred to the rollers. This is said to result in a light footprint - avoiding the extra soil compaction caused by requiring extra road-wheels to carry the additional weight.

There's a choice of four different types of roller that may be fitted to the rear, including: cage-type; pack ring type; rubber packer type; or a tandem 'Conoroll'.

The chassis features an integrated folding and transport system for road travel, with a height of 4m and a width of 3m when folded. Either air or hydraulic brakes may be specified.

Three double-acting spool valves are required. The machine can be controlled via ISOBUS - as an option.
