ABSTRACT:
Apparatus for cutting and chipping trees and brush includes a housing telescopically received at the end of a hollow rectangular boom or secured onto the existing boom of a vehicle and for contacting tree limbs or brush to be cut and chipped. The housing has a cutting member at the front portion extending outwardly for cutting trees or brush and feeds the cut material into a chipper. The rear of the housing forms a rectangular duct and a pair of alignment guides extend angularly outward from the front portion to receive the trunk of the tree being cut. A pair of cable guides extend between the top of the housing to the front of the alignment guides to divert power lines or cables and prevent them from being cut. The chipper reduces the cut material to chip size for passage through the duct. A blower moves chipped materials rearwardly through the duct portion. A nozzle on the underside of the housing discharges fluid onto the remaining cut materials to seal the cut portion. The cutting member preferably is a cylindrical member with radially-extending cutting blades secured thereon and rotate in the opposite direction of the chipping member.
