PRETREATMENT CONTROLLER OF COMBINE HARVESTER

摘要

PROBLEM TO BE SOLVED: To provide a pretreatment part controller of a combine harvester, with which the drive of the pretreatment part interlocked with a traveling speed can be continued even if detection information of a driving speed is not outputted by troubles of a detection sensor or a malfunctioning of another control system. SOLUTION: A speed interlocking means for interlocking the traveling speed of a machine body through a traveling transmission system transmitted to a traveling apparatus with the driving speed through a pretreatment transmission system transmitted to the pretreatment part 13 and changing the driving speed can be changed from a speed proportional drive control to the proportional drive control of a main speed change lever position.
