ABSTRACT:
A method and apparatus for severing trees and other similar objects extending at least partially above and at least partially below the surface of the ground. A frame member which is mountable on a vehicle is moved in a substantially horizontal plane above the surface of the ground. A pair of circular cutting disks having sharpened peripheral edges are rotatably mounted on the frame laterally spaced from each other. The disks are arranged such that the imaginary planes formed by the sharpened edges of the disks are inclined from the surface of the ground and intersect at a point below the surface of the ground, such that the inclined planes have opposite slopes and such that the sharpened edge of one of the disks is substantially adjacent the sharpened edge of the other disk.
