Wedge ring roller: targeted reconsolidation . . .

A roller’s primary task is soil reconsolidation. The wedge ring roller uses rubber rings to form reconsolidated strips in which the seed is sown. The harrow that follows it covers the seed with loose soil from the unconsolidated area. Reconsolidating in strips ensures that the soil structure around the plants is always right for the current weather conditions, and so provides the best chance of rapid, uniform plant development. The wedge ring roller thus serves as insurance for just-in-time tilling. The wedge rings leaves a homogeneous, pre-consolidated strip without any stud marks. Compared to rollers with other profiles, this is a decisive advantage, resulting, above all, in a smooth run of the sowing coulters.        As a general rule, enclosed rollers perform better than open rollers, particularly on loose, light soils. Open rollers also become clogged up more easily than enclosed rollers. This is why the rubber rings in the wedge ring roller are fitted onto a closed cylinder. When the wedge rings sink into the soil they are carried across the full length via the centre barrel. There is no chance of sticking, clogging up or blocking!
