摘要

Harvester e.g. loading trailer, has spring support (21) positioned at the cutter bar (9) movable between a locking position and an unlocking position. The locking springs (34) are stressed in the locking position to lock the cutter and release the locking elements in locking and unlocking position respectively, such that the spring support is coupled by a coupler with the frame part (12). The coupler (23) presses the spring support into the locking position in the working position of the cutter bar and allow locking position and unlocking position in the non-working position of the cutter bar, for the spring support. A spring support block (27) is provided, by which the spring support is locked in the locking position relative to the cutter bar.
