ABSTRACT:
A depth control includes an actuator tube connected for movement with the rockshaft and having a threaded crank supported on the forward end of the tube. A valve operator bracket is slidably and nonrotatably received over the tube and includes a threaded portion engaging the crank threads to positively locate the bracket relative to the tube. The bracket carries a plunger which, as the rockshaft lowers the implement to the working position, is moved into contact with a valve actuator to close a valve and prevent further lowering of the implement. One turn of the crank gives the same positive movement along the tube each time the depth setting is adjusted so that working depth can be set very accurately and easily.
