RIDING TYPE PADDY FIELD WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a riding type paddy field working machine that easily avoids occurrence of improper ground height control of paddy field working apparatus and performs a lifting and lowering operation of ground-leveling rotor by a simple structure in spite of leveling ground by a freely rotatable and drivable ground-leveling rotor.

SOLUTION: The rotatable and drivable ground-leveling rotors 50 are arranged at the right and left sides of a ground sensor float 12. A pair of transmission means 60 and 60 for separately transmitting power to the right ground-leveling rotor 50 and the left ground-leveling rotor 50 are disposed. A right support means 70R for liftably and lowerably supporting the right ground-leveling rotor 50 on the frame 14 of the paddy field working apparatus and a left support means 70L for liftably and lowerably supporting the light ground-leveling rotor 50 on the frame 14 of the paddy field working apparatus are installed. An interlocking means for interlocking the right support means 70R and the left support means 70L is arranged and a drive mechanism for operating the left ground-leveling rotor 50 to the lifting side and the lowering side is mounted.
