Publication number: 20100163656Abstract: An improved brush cutter having an upper feed control member with stop, forward, neutral, and reverse positions also has a lower feed stop member with selectable sensitivity. Another aspect of the invention is to predict the feed roller shutoff point according to the rate of engine deceleration. According to another aspect, when the feed rollers stop feeding material into the cutters, to overcome drag on the cutters, a controller stops the feed rollers and then reverses them for a short time, and then reverses the rollers again if the problem is still present. To prevent jamming, a pressure switch senses when oil in a hydraulic motor system for rotating the feed rollers is too high and the controller momentarily reverses the feed rollers and then causes them to go forward, a cycle which can occur several times until the feed rollers are no longer stalled.Type: ApplicationFiled: January 6, 2010Publication date: July 1, 2010Inventors: Mark Robert Stelter, James L. O'Halloran, Dennis K. Gabler, Jeffrey D. Kernwein, Ivan R. Brand, Brian M. Johnson
