A combined tree feller processor has a head mounted to a boom with a three-axis coupling. The coupling allows an operator to control the orientation of the head. The head has tree processing means and a continuously rotating high speed saw for cutting trees. While trees are being cut the head is held firmly with respect to rotation about a third generally vertical axis. After a tree has fallen the third axis is in a horizontal position and is perpendicular to the longitudinal axis of the head. The head is allowed to float with respect to the third axis as the tree is processed.

[ I claim:] [1.] A tree felling and processing machine comprising:(a) a boom (27) having an end mounted to a vehicle and a free end;(b) a first member (78) pivotally mounted to said free end of said boom for pivoting about a first generally horizontal axis (36);(c) a hydraulic cylinder (79) linked between said boom (27) and said first member (78) for tilting said first member (78) about said first axis (36);(d) a second member (81) pivotally mounted to said first member (78) for pivoting about a second axis (38) perpendicular to said first axis (36);(e) a second actuator (90) linked between said first member (78) and said second member (81) for tilting said second member (81) about said second axis (38);(f) a hydraulic control circuit for selectively causing said second actuator (90) to either float or to firmly hold said second member (81) at a selected degree of tilt relative to said first member (78);(g) a processor head (72) mounted to said second member (81) by a rotary coupling (84), said rotary coupling (84) permitting said processor head (72) to pivot about a third axis (37) perpendicular to said first and second axes (36, 38), said processor head (72) comprising:(i) a tree-engaging grapple for engaging a tree while the tree is cut;(ii) tree processing means; and(iii) a tree feeder for moving a cut tree past said tree processing means; and,(iv) a substantially continuously rotating circular saw for cutting said tree;(h) a ring gear (94) on said second member (81); and(i) a motor (92) on said processor head (72) driving a pinion gear (93) engaged with said ring gear (94) for rotating said processor head (72) about said third axis (37).
