A cover plate 20 is introduced between the puller belts, to assist in keeping them free from clogging with weeds or other foreign matter. The front part of the plates 20 is tapered as at 22 to serve as guideways, assisted by spring guides 21, for the groups of flax plants to the bites of the puller belts. They are spaced between contiguous plates, as at 23, sufficiently to allow a free passage for the plants.
