Abstract: A sawing and chipping device for harvesting and chipping trees including a rotatable saw for cutting a tree, conveyor for conveying the cut tree and a chipping element for chipping the cut tree. The saw includes top and bottom surfaces and a peripheral edge. The chipping element is mounted on the saw top surface. When engaging a tree with the saw during rotation thereof, the tree is cut and subsequently conveyed by the conveyor onto the saw top surface to be chipped by the chipping element. In another aspect, the saw is mounted to a housing having an opening to receive tree chips leading to a container positioned beneath the saw bottom surface and including an outlet. The bottom surface includes turbine blower means for blowing the chips through said outlet during rotation of the saw. In another aspect, the conveyor is configured to convey a cut tree inwardly and downwardly. Saws for such devices are also disclosed.
