Title:
MACHINE BODY LIFTING APPARATUS IN PADDY FIELD WORKING VEHICLE
Document Type and Number:
Japanese Patent JP3245332
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a machine body lifting apparatus in a paddy field working vehicle enabling the automatic controlling of vertical motion of a machine body by further grasping right and left side clutch levers after the clutches are disconnected by the manipulation of the levers.
SOLUTION: A returning spring 93, which energizes an oil pressure changing valve 10 toward the opposite direction against the movement of the oil pressure changing valve 10 for lifting a machine body, is linked between an operation arm 10a and a swinging member 71. Side clutches are disconnected by the operation of right and left side clutch levers 52R, 52L. The levers 52R, 52L are constructed in such a manner that further grasping of the levers from the disconnecting position of the clutches can adjust the sensitivity of a float 11 sharper in a lowering direction of the machine body and duller in a rising direction. Thus, the automatic controlling of the vertical motion of the machine body is enabled through the swinging member 71 by oil pressure.
