FLYWHEEL TREE FELLER AND BUNCHER Abstract of the Invention A flywheel tree feller is slidably mounted in a base and comprises a combination drive and saw chain peripherally engaging and driving a circular saw bar sprocket in flywheel rotation with no relative rotational motion therebetween. The circular saw bar sprocket is the outer flywheel race of a ball bearing, the inner stationary race of which is supported semi-peripherally to eliminate a center hub and supporting axle thereby cross-cutting for more than the full radius of the flywheel race, rather than a lesser chord, and thus to fell larger trees. A pusher for biasing a cut tree from falling in the direction of the flywheel feller is mounted on the base and also a pair of reaction grapples for loosely closing around a tree to hold the base against reaction displacement by the operating forces of flywheel feller and pusher. A dual bunching assembly is mountable in place of the pusher and comprises upper and lower sets of grapples pivoted for opening and closing the upper set for additionally swinging normal to the plane of their opening and closing thereby allowing the dropping of trees without shock to the base and for picking up felled trees. A ball race is mounted on the rear of the buncher assembly with its plane normal to the opening and closing plane of the grapples for tilting the base and buncher assembly sideways for cutting and bunching on a slope. A back platform of the buncher assembly defines a sharp edge for cutting brush and small diameter trees and catching and holding them, and bunching them over the top when the buncher assembly and base is rotated at least more than ninety degrees downward and forward.
