摘要：
A liquid applicator implement includes a boom vertically adjustable with respect to a vehicle. The boom supports a plurality of drop assemblies laterally spaced along the boom in communication with a liquid product source. A height sensor assembly is attached to at least one of the drop assemblies and generates signals indicative of a distance between the drop assembly and a ground surface as the vehicle advances in a direction of travel. An adjustment mechanism coupled to the boom is responsive to the signals generated by the height sensor assembly for vertically adjusting the boom. In some embodiments, a breakaway sensor is used to determine whether at least one drop assembly has broken away from its normal substantially vertical operating orientation. In some embodiments, a data processing and/or height control action is determined upon detection of a breakaway event.
