Ecological Systems and Devices Annotation << Back The field investigations of conical roller-bearing canal cutter Samkharadze V.I. On the basis of technology for cutting of drainage collectors on drained, heavy clay soils of Colchis lowland, the technology for extrusion of the channel with smooth slopes has been chosen. The compound driven element of the separate disks is made for decrease of draught resistance. The field tests of canal cutter are realized on the different soils. The draught resistance is established on different speeds.
