A device for coupling the cutting platform to a combine harvester

摘要

A device for coupling the cutting platform to a combine harvester includes a rotary hook (8) which can be rota­ted by means of a control lever (10) between a rest position and an operative position in which it engages a catch element carried by the cutting platform. The book (B) is held in the operative position by a locking member (23) which is resiliently biassed towards the locked position and can be moved away from this posi­tion by means of a cam member (16) which is interposed in the connection between the control lever (10) and the hook (8). The connection is such that rotation of the control lever (10) towards the locked position causes a corresponding rotation of the cam member (16) and the hook (8) whilst rotation of the control lever (10) towards the unlocked position is transmitted to the hook (8) by the cam member (16) only after the cam member (16 ) has completed a first section of its travel, which is necessary to move the locking member (23) away from the locked position. Preferably, two hooks (8) are provided which are operable by means of a pair of control levers (10) situated on the same side of the combine harvester.
