Cambridge rollers consist of alternately-fixed cast smooth rings and flat toothed disks, with the latter having slightly bigger diameter. The disks are installed onto the protruding part of the smooth ring hub and may turn independently. The difference in rotational speed between the rings and disks allows for removing the soil sticking to the roller. The rollers crush the soil chunks and knead them, while leaving moderately loosened soil. Our range of products includes the smooth rings of Ø 480 mm with 62-mm opening, hub width 104 mm; Ø 430 mm with 52-mm opening, hub width 100 mm; toothed rings Ø 490 mm with the 105-mm opening, width 17 mm, Ø 450 mm width 90-mm opening, width 17 mm.
