Cart with leverage arm for felling cut trees - has adjustable handle to allow easy leverage irrespective of tree cut above ground

摘要

The lever cart for felling and removing cut tree trunks has a handle (19) fitted at the bottom with the felling lever (22) which extends at right angles. The handle is suspended from the frame (2) above the rotary axes (9) so that at least in one position of the shaft (5) it can swing a limited extent about a pendulum axis (18) which stands perpendicular on the centre plane. The distance between the felling lever and pendulum axis can be adjusted accordingly. ADVANTAGE - Very favourable lever ratios are provided so that only comparatively slight pressure has to be applied to the shaft in order to raise the tree trunk. By adjusting the lever on the cart the shaft can be placed in the optimum position irrespective of the height of the cut above the ground.
