PADDY FIELD WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a paddy field working machine which can pivotally support a hydraulic rock lever and a sub speed change lever in a simple structure. SOLUTION: This paddy field working machine is characterized by disposing the swinging axis of the hydraulic rock lever for operating a rock valve for closing an oil route to stop the lowering of a paddy field implement and the swinging axis of the sub speed change lever 41 for operating a sub transmission 23 for driving, on an identical axis x2. The oil route is used for a hydraulic cylinder for lifting the paddy field implement by the charging of an oil and for lowering the paddy field implement by the discharging of the oil.
