Vermeer’s BC900XL can chip heavily branched material up to 9 inches in diameter, and is designed for line clearing and general cleanup needs. A 9-inch by 14-inch feed opening reduces the need to trim branched material before feeding it into the chipper; a 33-inch-diameter disc rotates at 1,400 rpm and features two steel chipper knives with two usable cutting edges each. Two shear bars have two usable edges each to help extend wear life. The patented SmartFeed system monitors engine rpm and automatically stops and reverses the single horizontal feed roller when feeding larger, hardwood material. The unit is equipped with safety features such as a long feed table design, bottom feed stop bar and a four-position feed control bar.
