Abstract
A brush chipper with feed rollers and a winch has an interlock control with feed roller disabled position and a feed roller enabled position, spring loaded to the feed roller disabled position to encourage or require the use of the winch line to move it into a feed roller enable position. A winch control is provided that selects between a winch freewheel condition and winch drive condition. A connection is provided between the interlock control and winch control such that the interlock control automatically moves to the feed roller disabled position whenever the winch control is moved to the freewheel position.
