Managing cultivators’ depth guidance

The depth guidance of semi-mounted cultivators has so far generally been managed with guidance wheels mounted on the vehicle frame and the following roller.

This system works relatively well on level ground, where adherence to the set working depth and the load on the support wheels is relatively constant.

On uneven and rough land, and in particular for long cultivators, they often work too deep when crossing over a hump, and too shallow when passing over a hollow or dip.
