ROLLING CONTROL APPARATUS SEEDLING PLANTER

摘要

PROBLEM TO BE SOLVED: To reduce hunting in a seedling planter by sensitizing the sensitivity of a rolling control in a seedling planting operation and making the sensitivity of a rolling control in traveling on a road insensitive. SOLUTION: This rolling control apparatus for a seedling planter is equipped with an absolute horizontal control mode for detecting the angle of inclination of right and left of a body having a seedling planting apparatus and a pair of right and left wheels 2 by an inclination sensor for changing support height of the right and left wheels 2 and for controlling the body in a horizontal state and a ground horizontal control mode for controlling the body in a right and left parallel state on the surface of a field by difference in ground height between side floats 5 at both right and left sides of the lower part of the body and sets the control sensitivity of the absolute horizontal control mode more insensitive than the ground horizontal control mode.
