A method of producing a disk mower cutter bar housing, comprising:
- forming an upper plate and a lower plate of the housing;
- assembling the formed upper plate and the formed lower plate by welding by a laser beam, without addition of material, to form a casing;
- cutting out holes on the casing, by a laser beam, the holes configured to receive bearings of disks and supports of intermediate drive gears;
- closing two ends of the formed casing with fitted lateral edges, by welding with addition of material,
- wherein the forming of the lower plate comprises forming a front edge and bending the lower plate to form a vertical partition parallel to said front edge, said vertical partition being between said front edge and a rear part of the lower plate.
