Abstract

Structured operation tools to raise and lower Level for agricultural machinery in which the working equipment (4) is installed in place. The rear of the propulsion vehicle body (1), the working device (4), moves the articulated mechanism (3) parallelogram. Caused by stretching and shrinking Hydraulic piston body (2), parallelogram coupling mechanism (3) with coupling pair The upper right and upper left (7) the lower coupling (8) and the upper rear coupling (9) the hydraulic pistons (2) are attached to the coupling mechanism (3) parallelogram by Through spring suspension (7), coupling mechanism (3), parallelogram Will move up By contraction of the hydraulic piston (2) and moving down by extension of the hydraulic piston (2).
