BACKGROUND ART AND PROBLEMS TO BE SOLVED BY THE INVENTION Conventionally, the inclination of a working machine towed by a tractor in the front-back direction is detected, and the gap between the tractor main machine and the working machine is adjusted so that the working machine is horizontal in the front-back direction. There is a reference example for controlling the expansion and contraction means of the connecting member, such as in Japanese Patent Application Laid-Open No. 60-1215. There was nothing to keep it in a horizontal position.

Functions and Effects of the Invention The tilling device connected to and towed by the vehicle body (1) is connected to the tilling rotor (2).
), the tilling cover (4) covers the rotation area of the tilling rotary body (2) to prevent soil from scattering, and a part of the rear cover of the tilling cover (4) covers the rotation area of the tilling rotary body (2). The tilling depth is detected by contacting the tilled soil surface, the tilling depth is controlled based on this detection, and when the tilling device is moving forward while maintaining the tilling depth constant, for example, when the tilling device is tilted backwards and downwards, a part of the rear cover is removed from the tilling position. The tiller is pressed against the soil surface and the tillage depth is detected to be deeper than the actual tillage depth, but the tilt sensor (5) installed on the tillage frame (3) detects the backward slope, so this detection is not possible. The tilling cover (4) changes its front and back inclination with respect to the tilling frame (3), and the posture of the tilling cover (4) is corrected in the direction of lowering the front side and raising the rear side, leaving the ground posture unchanged. The predetermined posture is corrected and maintained.

このため、耕耘カバー(4)の後部カバ一部も所定の対
地姿勢に修正維持されるので耕深検出値を狂わせること

Therefore, a portion of the rear cover of the tillage cover (4) is also corrected and maintained in a predetermined posture relative to the ground, so that it can be used for tillage depth control without disturbing the tillage depth detection value.
