DOUBLE DISC DD ROLLER
DD THE DOUBLE RINGS
THE NEED FOR CONSOLIDATION
Effective consolidation plays a crucial, but often under-appreciated part in modern arable farming. As part of a reduced tillage or plough based system, it can save valuable time, reduce costs and increase yields. Fundamentally, it plays a key role in combating the problem of compaction, which is a barrier to root growth and water infiltration and a major factor in poor soil structure leading to run-off and erosion. The well-proven 600mm diameter DD rear roller provides positive depth control and leaves a high quality corrugated, weather-proof surface. Rollers are equipped with heavy- duty scrapers and sealed-for-life ‘non-grease’ bearings. Manufactured from the highest quality Chrome Boron steel, the rings have a self-sharpening cutting edge mounted on a broad, carefully angled shoulder. This enables parted halves allowing the fissures to break down, while also contacting over 80% of the soil surface to consolidate and level the seedbed, leaving a ridged, weather-proof surface.

Clods are cut and fissures propagate through a result of the DD action, Broken or cracked clods are left in an ideal state for further weathering
