摘要： PROBLEM TO BE SOLVED: To provide a paddy working machine having an improved turning function on butt even under different paddy field conditions utilizing features capable of performing small turn while breaking the rear wheel at the turning inner side. SOLUTION: This paddy working machine has side breaks 38 for the right and left rear wheels, a pair of the right and left breaking pedals 37L and 37R which independently actuate each of the side breaks 38 for rear wheels, a pair of hydraulic cylinders 41L and 41R, and an angular sensor 46 which can detect the steering angle of the front wheels. This mechanism enables the generation of a manual breaking state where the side break 38 is actuated for breaking and locking by the manual operation of the breaking pedal 37L (or 37R), and an automatic breaking state where the side break 38 for the rear wheel of the turning inner side is actuated in half breaking in preference to the manual breaking state when the front wheels are stirred by an angle larger than a preset angle.

摘要： PROBLEM TO BE SOLVED: To further improve the vertical movement control performance by damper adjustment with vertical movement control sensitivity, traveling speed during planting work and traveling acceleration and deceleration, etc., as conditions. SOLUTION: This vertical movement controller is provided with an automatic vertical movement control means B capable of stably maintaining the height level to the ground of a planting device by arranging parallel a suspension spring and a damper 12, serially connecting them to a hydraulic cylinder 8 for vertical movement and switching and operating the control valve 24 of the hydraulic cylinder 8 based on the vertical movement detection of a ground float 22 and a sensitivity setting dial 30 for adjusting the vertical movement control sensitivity. In this case, the damper 12 is constituted to an attenuation force adjustment type and a sensitivity/damper control means C for linking the sensitivity setting dial 30 and the damper 12 so as to strengthen attenuation force when the vertical movement control sensitivity is operated to a sensitive side and weaken the attenuation force when the vertical movement control sensitivity is operated to an insensitive side is provided.
