SELF-PROPELLED HARVESTER Russian patent published in 1995 - IPC

FIELD: agricultural machines. SUBSTANCE: self-propelled harvesting machine, for example a combine harvester, comprises a front-mounted working tool, secured on the ends of piston rods of the machine hydraulic cylinders. The rod ends of hydraulic cylinders communicate with one another via a pipe with a switch-over valve while the head ends, through a pipe. This allows the working tool to turn around the middle longitudinal centerline of the machine without changing its center of gravity This, in turn, ensures its stable road performance characteristics. EFFECT: improved design. 5 cl, 2 dwg
