動調節装置。[Claims for Utility Model Registration] (1) The backbone beam and the channel beam are pivotally connected so that the front link and the rear link form a parallelogram with a low front and rear height,
The entire circumference of the arc-shaped guide rod is attached to the pivot point between the lower end of the front link and the central beam, and is attached to the channel beam so that it can be slidably engaged with the channel beam. It has a non-linear characteristic characterized in that it surrounds a compression spring having a length shorter than Automatic height adjustment device in cultivator. (2) A spacer is interposed at the front, rear, or at least one end of the compression spring surrounding the arcuate guide rod so that the degree of elasticity of the compression spring can be adjusted. Automatic adjustment device in a cultivator with non-linear characteristics.
