Abstract

A cutting device for agricultural harvesters has a conveying channel and pivotably supported cutting knives arranged in a row on a frame. The cutting knives project in the cutting position into the conveying channel. A conveying member with conveying tines, rotatingly driven about a horizontal axis, interacts with the cutting knives for comminuting crop. Individual adjusting devices, each associated with one cutting knife, yieldingly support the cutting knives in the cutting position. A knife switching device is provided to move the cutting knives from the inoperative position into the cutting position. With a preselecting device a desired group of cutting knives can be selected that is pivoted into the cutting position upon activation of the knife switching device. The preselecting device is activatable with reduced force expenditure by eliminating resistances, caused by adjusting and connecting devices of the knife switching device, when preselecting the desired group of cutting knives.
