Abstract

A harvester is provided with a draper head that has a frame extending substantially across a working width of the draper head. Cutting elements are arranged at a front side of the draper head and connected to the frame. Conveying surfaces and conveying members transport cut crop from the cutting elements to a discharge location of the draper head. A reel extends transversely to a working direction of the draper head across the working width of the draper head. Reel support arms are pivotably supported on the frame and support the reel. A hydraulic adjusting drive is operatively connected to the reel support arms to pivot the reel support arms to carry out a height adjustment of the reel. A hydraulic circuit is operatively connected to the hydraulic adjusting drive and has a hydraulic valve that is able to lock the hydraulic circuit.
