Abstract
PURPOSE:To control left and right horizontal attitude in a working machine for paddy field in high precision capable of operating smooth and light push and draw of spool, by arranging a supporting shaft of an oscillating arm and a spool connecting part at approximately at same height in a neutral state. CONSTITUTION:One end part of an oscillating arm 33 is long extended toward the side of a valve 28 for horizontal control at the side of a valve 27 for rise and fall control and a spool 28a of the valve 28 for horizontal control is fixed through a connecting pin 33d to an extended piece 33c. The spool 28a is pushed and drawn by vertical oscillation of the oscillating arm 33 around a shaft 32 as a support to carry out valve change. In a neutral state, namely in a state where both left and right detecting floats 11 have attitude of the same height, the oscillating arm 33, the supporting shaft 32 and the connecting pin 33d of the spool 28a are positioned at an approximately straight line and arranged at approximately the same height. Consequently, the spool is smoothly pushed and drawn without applying force in the lateral direction to the spool.
