A machine for removing limbs from trees is described and includes a frame and a pair of saws supported by the frame, the saws each having a longitudinal axis, and being supported by the frame for rotation about the longitudinal axis. The saws include a blade having a cutting edge and being wrapped around the axis in a helical pattern, and the saws are supported in parallel side-by-side relation and are adapted to engage a tree with tree disposed between the saws and with the tree being generally parallel to the longitudinal axes of the saws. The saws are adapted to be rotatably driven about their axes and toward each other. The machine also includes a pair of rollers for clampingly engaging a tree, for pulling the tree in the direction of the longitudinal axes, and for rotating the tree as it is pulled.
