Abstract
A vehicle has a tree shear mechanism mounted thereto, which is raisable and lowerable relative to the vehicle. The tree shear mechanism may also be tilted about a longitudinal axis of the vehicle so that with the vehicle on ground of one level and slope, and the tree to be sheared on another ground level and slope, the tree shear mechanism can be properly positioned for appropriate shearing of the tree.
