The width of the hydraulic sensitivity adjustment 1111 can be adjusted by taking advantage of the respective advantages of the t' + l1i) h type d) and the norot angle of attack adjustment method, and compensating for the drawbacks of the two. /=
This is a part of our project that provides a hydraulic sensitivity adjustment device for fil transplanters.

For this purpose, the tree 1'6 light detects the car while joining the -no l-1-l, and shoots it against the traveling body; Hydraulic control system 1/7 (
To adjust the sensitivity of each movement, use the first sensitivity + 5 [adjustment ■ 1) system, which corresponds to the vertical movement of the float, to the oil 11 control system, which corresponds to the vertical movement of the float. '1st sensitivity tone nb
