特徴とする乗用型耕耘機。A tilling device 3 is installed on the tractor 1 so that it can be raised and lowered via a lift arm 4 and a single-acting lift arm cylinder 7 interlocked therewith, and is also installed so that it can be tilted freely in the left and right directions of the vehicle body via a drive mechanism 5. Rotor recovery 20 of device 3
A plowing depth control mechanism 26 that is provided to be swingable and that automatically operates the cylinder 7 to maintain the swing angle of the rotary cover 20 within a set range based on the displacement of the rotary cover 20. and an inclination sensor 9 for detecting the horizontal inclination state of the tilling device 3 with respect to the horizontal plane, and the inclination sensor 9 and the drive mechanism 3 are linked to allow the tilling device 3 to move in the left-right direction of the vehicle body. The drive mechanism 5 is equipped with a rolling control rod structure 27 that automatically operates to maintain the ground attitude of the tiller 3 in a horizontal or almost horizontal attitude, and furthermore, the drive mechanism 5 is provided with a rolling control rod structure 27 that automatically operates to maintain the horizontal or almost horizontal attitude of the tiller 3 relative to the tractor 1. An attitude sensor 13 is provided to detect the state, and an attitude control mechanism 29 is provided that stops the operation of the rolling control mechanism 27 and automatically operates the drive mechanism 5 so that the attitude sensor 13 detects a specific tilt state. The plowing depth control mechanism 26 is configured by a riding-type tiller equipped with the cylinder 7.
A return passage 1B is connected to the pressure oil supply passage between the control valve 11 and the control valve 11 therefor, and a return passage 1B is connected to the pressure oil supply passage for releasing supply oil with the control valve 11 in the upper fold operation position. A degree adjustment valve 19 is interposed, and the opening degree adjustment valve 19
and the rotary cover 20, the rotary cover 2
As 0 oscillates upward, the opening becomes smaller, and ”
- The rotary cover 20 is connected to the lift arm 4 through a mechanical linkage mechanism 24 so that the degree of opening increases as the rotary cover 20 swings downward, and the lift arm 4 A riding tiller characterized in that a starting switch 30 for the attitude control mechanism 29 is attached so as to act accordingly.
