  • Patent number: 6964442
    Abstract: A log rocker has a long lever arm with a back cylinder fulcrum at its bottom end. Also attached to the bottom end of the lever arm is a semi-circular, curved, pair of prongs and an upper, semi-circular shaped, pivoting surround arm. The surround arm has a spike at its outer end. The lever arm also has a handle at the top and a foot brace about one-third from the ground. To use the device the logger forces the pair of prongs underneath a log and then locks the log onto the rocker by rotating the upper, surround, pivot arm and driving the spike into the log to secure the device around the log. The lever can then be rotated to allow the logger to raise the log up off the ground and onto the cylindrical fulcrum for cutting.
