FIELD: agriculture.
SUBSTANCE: invention relates to agricultural engineering, namely to the coulters of drilling machines. The coulter comprises a centre hoe, a plate and a seed distributor. The coulter is equipped by a holder fixed behind an ellipsoid seed-and-fertiliser tube. The upper part of the seed-and-fertiliser tube is inclined forward. There is an insertion in the lower part of the seed-and-fertiliser tube. A rod which is bent and placed beyond the coulter working zone is fixed to the insertion along the circular arc.
EFFECT: uniformity of seed distribution is ensured, tractive resistance is decreased and sticking of plant residues on the coulter is prevented.
