Double Disc Roller

Overview

DDW

The basic design comprises of two rollers, arranged one behind the other, consisting of enclosed, welded steel dishes with serrated outer rims mounted in pairs. Both rollers feature an outer diameter of 600 mm. The dish elements are fitted on a shaft at a spacing of 25 cm, resulting in a point spacing of 12.5 cm. The dishes are low wearing and additionally fitted scrapers keep the rollers free from sticking soil.
In addition to the excellent, strip-wise reconsolidation effect, the Double Disc Roller, specially when in those heaviest of soils, achieves a very good crumbling. Furthermore it is characterised by its high carrying ability, good soil and trash passage and an optimum self-driving effect. It is completely insensitive to stones because, due to the large dead weight
of the rollers, stones are pressed back into the soil. For the soil horizon, the Double Disc Roller leaves a rough soil surface and thus provides little vulnerability to capping and a good air and water exchange within the worked soils.
