    Abstract: A rim driven rotary cutter for a tree felling head wherein the drive pinion and saw disc are in substantially the same plane, teeth on the drive pinion mating with the trailing face of the cutting formations on the saw, both being of a standard gear tooth design. The other face of the cutting formations have a cutting edge permanently or detachably mounted thereon. The circular cutting disc is mounted on a base plate and journal led for rotation on one or more annular bearings. Debris, such as chips resulting from cutting are removed by an idler having projections mating with the teeth of the cutting disc and/or an air jet suitably located to propel the chirps from between the cutting members and/or an opening in the frame allowing the chips to discharge by virtue of centrifugal forces.

    Abstract: An attachment for a mobile vehicle for picking up residue left behind a tree harvesting operation and cutting up the residue into smaller pieces and a mobile, selfpropelled vehicle having an attachment of the foregoing mounted thereon. The attachment includes a residue pick-up assembly comprising a plurality of spaced apart arms driven to rotate so as to pick up debris lying on the ground and feed the same to a passage extending through a housing on which the pick-up is mounted. The arms of the pick-up operate in conjunction with knives in the passageway to cut the picked up material into smaller pieces to prevent accumulation of cut-up residue in the passage there is provided in one instance a driven impeller for propelling the cut-up residue through the passage and discharge the same through an outlet therefrom, and in another instance additional knives are mounted adjacent the base or root of slots in a base plate through which the arms of the pick-up travel during rotation of the pick-up. The foregoing attachment is mounted on a mobile, self-propelled vehicle of an articulated chassis type having a debris collecting device mounted thereon. The device for collecting the cut-up debris is preferably a container pivotally mounted on the vehicle with power means to move the same so as to be self-dumping.
