ABSTRACT:
A method of whole tree chipping and whole tree chipper with a funnel-shaped receiving structure for receiving the butt end of a tree while the top of the tree is supported by the ground, and for bending limbs thereof, and a pair of free-floating feed rollers for engaging the periphery of the tree and feeding the tree to a chipper. The funnel may have teeth disposed along the interior surface thereof and be rotatable automatically in response to hang-ups within the funnel to eliminate the hang-ups by twisting and cutting of the tree limbs. Hydraulic rams preferably bias the feed rollers toward each other, and bias them to a particular orientation with respect to the opening in the funnel. The centerline of the entrance to the chipper is located in line with or slightly above the centerline of the opening in the funnel, and preferably the funnel opening is slightly smaller than the chipper entrance.
