Abstract:
Disclosed are an optical system and method for centering a tree within a tree spade apparatus that is mounted to a vehicle. Typically, the center point of the tree spade is difficult to align with the axis of the trunk of the tree. The present embodiments describe a projected pattern of light incident upon the tree trunk that assists the operator of the tree spade in centering the spade around the tree without additional assistance.
