Document Type and Number:
WIPO Patent Application WO2002037946
Kind Code:
A8
Abstract:
An improved brush chipper (10) having an upper feed control member with stop, forward, neutral, and reverse positions also has a lower feed stop member (31) 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.
