FIELD: machine building.
SUBSTANCE: invention relates to a mechanism for cleaning dirt from caterpillar tracks. Driving wheel (10) for caterpillar drive (12) of agricultural working machine contains at least one drive wheel (20, 42). At least one drive wheel (20, 42) comprises bearing cantilevers (28) extending from drive wheel (20, 42) axis of rotation (26) like wires in radial direction. At least between each two adjacent cantilever beams (28) radially outside there is gap (34). On each cantilever beam (28) at least one friction element (36) is located radially outwardly, in particular with possibility of dismantling, for interaction with caterpillar band (14) with force closure.
EFFECT: better transmission of force between drive wheel and caterpillar band.
