Brush cutting device
US-7322111-B2Abstract
A lever actuated cutting tool that allows ground level cutting of shrubs and small trees from a standing position. The design of the cutting tool takes advantage of the principles of leverage and resistive force, and also incorporates a pendulum swing, to provide a tool that is able to generate a tremendous amount of cutting force. A padded handle is provided at the long end of the lever and a first sharpened steel blade is attached to the cutting end of the lever. The lever is rotate-ably attached to the fulcrum and the fulcrum lies on the ground during operation. A second sharpened steel blade is immovably attached to the base of the fulcrum, and the trunk of the shrub to be removed is positioned in between the two blades. The cutting action is accomplished by moving the lever downward toward the ground. The force applied by the user is multiplied by the lever and transferred to the first cutting blade. The resistive force supplied by the ground is transferred, via the base of the fulcrum, to the second cutting blade. And the pendulum swing motion allows the first blade to pass cleanly over the second blade.
