Abstract
A brush chipper having a guard (38) which is released to block the inlet (12) to the cutter (10) when an emergency condition is sensed. During normal operation of the chipper, the guard (38) is held out of the path of brush to the cutter (10). When a weight, in excess of a normal brush load, is sensed, as for example when the chipper operator is being drawn into the chipper, the guard (38) is released automatically and moves to block the inlet (12) to the cutter (10). This prevents the operator from being drawn into the cutter (10).
