摘要：
A system includes a boom. The boom includes a first section and a second section. The system includes a first actuator element configured to drive rotation of the first section, a second actuator element configured to drive rotation of the second section, and a locking element configured to block rotation of the first section and to block rotation of the second section while the locking element is in an activated position. Moreover, the system includes a sensor element disposed on the boom. The sensor element is configured to output a signal indicative of a first height between the first section and a field and a second height between the second section and the field. The first and second sections are configured to independently rotate based on the received signal to maintain a desired height between the field and each of the first section and the second section.
