Combine feeder drive control

摘要

A self-propelled combine for harvesting a crop and including a crop threshing and separating mechanism and a feeder for feeding crop material into the threshing and separating mechanism. The feeder has an electro-hydraulic control system for engaging and disengaging drive to the feeder. An electronic control system monitors the speed of the feeder drive and actuates the electro-hydraulic control system to disengage the feeder drive in response to sensing feeder drive speed below a predetermined minimum.
