Zusammenfassung:A disc cutter (136) for an agricultural implement includes: a disc body (320); a knife nut (340) coupled to the disc body (320); a knife (350) including a knife opening (351) in which the knife nut (340) is disposed, the knife (350) being configured to rotate about a rotation axis (RA) defined by the knife nut (340); and a spring plate (360) carrying at least two protrusions (361A,361B), the spring plate (360) being biased towards the disc body (320) such that in a first position the spring plate (360) bears on the knife (350) so a plane (P) defined through a portion of the knife (350) extends through the protrusions (361A,361B) until an overload force applied to the knife (350) forces the knife (350) over at least one of the protrusions (361A,361B) and moves the spring plate (360) to a second position.
