The draw members being arranged in tandem and mutually laterally offset relationship relatively to the direction of travel. The draw members are interconnected by linkages, each consisting of an intermediate bar extending at least partly in an oblique direction relative to the direction of travel. At least one part of each linkage is designed as a carrier of downwardly directed rake tines.
