Abstract

A harvester for a multirow corn crop comprises a cutting head whose leading edge is formed with individual cutting members at each of a plurality of channels. The channels run rearwardly and unite at the rear portion of the head. Each of the channels is provided along one flank with a yieldable wall and along the other flank with a chain having entraining members reaching substantially across the full width and height of the channel. The entraining members are preferably of L-shape in plan view and have a pair of friction strips resting against the respective wall of the channel above and below the chains.
