Self-propelling harvester thresher with composite cutting table

A self-propelling harvester thresher, comprising a cutting table, said cutting table including a cutter bar, a drawing roller, a first cutting table part having two side walls, a first bottom plate and a rear wall provided with a throughgoing opening, and a second trough-shaped cutting table part including two walls and a second bottom plate;

• a plurality of cylinder-piston units arranged under said bottom plates parallel and spaced from one another and moving said second cutting table part relative to said first cutting table part steplessly for shortening or lengthening a distance of said cutter bar relative to said drawing roller;
• a releasable locking element limiting a displacement path within a maximum displacement of said cutting table parts relative to one another in which said bottom plates and said side walls overlap one another so that a maximum stroke of said cylinder-piston units is greater than said displacement path of said cutting plate parts limited by aid locking element, said cylinder-piston units bieng arranged so that when said locking element is in a released position and piston rods of said cylinder-piston units are completely extended, a space is provided between said cutting table parts;
• and means for overlapping said space, said means including an intermediate bottom and two intermediate side walls.
