| 摘要 |
A harvesting machine includes a harvesting header with flexible cutterbar assembly sections, multiple arms supporting respective cutterbar assembly sections, and a header height sensing system including sensors and a pair of electrical comparator circuits. At least two sensors are provided for each cutterbar assembly section, with each sensor coupled to one of the support arms. The electrical comparator circuits each include sensor inputs in electrical communication with the sensors coupled to the respective cutterbar assembly section to receive arm position signals associated with each cutterbar assembly section.
