REAR ROLLER
THE NEED FOR CONSOLIDATION
REDUCES THE RISK OF EROSION IN THE TOPSOIL Rollers have been designed to ensure an efficient soil compaction to reduce the soil porosity and limit evaporation in dry conditions but also to prepare an optimal seedbed as a good start for perfect growth and high yields.
The rollers are parallelogram guided. Combined with a coulter bar which is mounted on the roller frame, the depth control is independent of the power harrow.
Cracking performance.
The roller on a power harrow is an elementary tool with different tasks: • Supporting the exact working depth of the machine is especially in light conditions. • Optimal soil to seed/root contact to enable efficient nutrient transfer. • Breaking of clods in order to have a fine seedbed but at the same time keeping the soil structure for reduced soil erosion, as the soil is both structured and stable. • Improved drainage and water infiltration, especially important in wet years when a good, consolidated soil structure ensures access to plant root systems for water, air and nutrients. • No separation or raising of straw and residues. Minimal moisture loss, is especially important in dry years when crops which lack moisture suffer badly. • Reliable working without stick of the soil surface by slipping. Easy maintenance and cleaning.
