Summary:A system of cutting blades, especially for a press duct of a fodder harvester, has two sets of retracting blades, with at least one blade (5) separately mounting to the other blades (3). The front ends of the blades have a pivot mounting on a fixed bar (6) with the rear ends of the blades gripped by crank arms to raise or retract the blades. One set of blades is controlled by a first set of crank arms (9) fitted to a first control shaft (10) which is rotated by a servo cylinder (13) and a drive crank arm (12). The other set of blades is controlled by a second set of crank arms (15) pivot mounted on the first control shaft and rotated about the first control shaft by a second servo cylinder (22) and a double armed drive crank (18). Each servo cylinder is fitted with a separate hydraulic overload protection to retract its set of blades. Die Erfindung betrifft ein Schneidwerk für/an landwirtschaftlichen Erntefahrzeugen, insbesondere für landwirtschaftliche Pressen, mit mehreren in Reihe nebeneinander angeordneten, formschlüssig mit wenigstens einer Messertragwelle (10) verbundenen Messern (3), welche nur gemeinsam um eine Schwenkachse (6) wahlweise in eine Schneid- (30) oder Nichtschneidstellung (28) verstell- und bei Überlast nur gemeinsam ausweichbar sind. Um dieses Schneidwerk hinsichtlich der Verstellung der Schnittlänge zu verbessern, wird erfindungsgemäß vorgeschlagen, dass das Schneidwerk wenigstens ein Messer (5) aufweist, das mit einer Verstelleinrichtung (14, 17, 18, 22, 26) derart eingerichtet ist, dass es unabhängig von den Messern (3) verstell- und ausweichbar ist.
