DIRECTLY ACTUATED DEPTH CONTROL |
摘要 |
A depth control system particularly useful for single point depth control on an agricultural implement includes a valve and actuator mounted directly to the pivotal connection areas of a hydraulic cylinder that controls height. Cylinder moti on directly controls valve actuation independently of complicated linkages to reduce the size and cost of the system and substantially overcome hysteresis problems.</SDOA B>
