Closed rollers

In general, closed rollers are better weight carriers than open rollers, especially on loose and light soils. Closed rollers also tend to clog less. It is precisely for this reason that the rubber rings are fitted on a full tube on the wedge ring roller and the wedge ring roller with Matrix profile. When the rings sink into the loose soil, the tube carries the weight across the entire length. There is no chance of sticking, clogging or blocking up.
