Abstract
An agricultural trench depth sensing system having a trench implement adapted to be disposed in a soil trench opened in a soil surface. In one embodiment an ultrasonic sensor detects a distance to an upper surface of said trench implement or a target disposed thereon. In another embodiment, said trench implement includes one or more fingers which rotate with respect to said trench implement to detect the soil surface relative to said trench implement. In another embodiment, said trench implement includes side sensors for detecting the sidewall of the soil trench.
