FIELD: agricultural engineering, in particular, pull-type headers for mowing of cereals and laying cut stems in windrow on field. ^ SUBSTANCE: header has drive part with transverse beam and columns, and platform with tie-rods. Platform has lifting and lowering hydraulic cylinders and spring units for balancing thereof. Tie-rods are interconnected by cross-piece and are pivotally coupled with their ends to columns. Hydraulic cylinders are mounted on transverse beam brackets. Stops mounted on transverse beam are cooperating with levers in upper position of platform. Transverse beam is connected with upper part of platform through tightening devices and balancing spring units. Header provides following of field relief in transverse direction and keeps optimal angle of platform inclination to field surface on changing cutting height of grain stand. ^ EFFECT: simplified construction and increased efficiency. ^ 6 dwg
