What weighs 4.5 tons, measures 8 feet in diameter, it\’s manufactured from pure steel, and may destroy 50 acres of woods per hour? The bowling ball lumbering machine, that\’s what.

Back within the 50s, it was believed to be the be-all, end-al of all lumbering techniques ever developed. Get the ball, set it in motion using two tractors, and watch it snap any tree across its path like toothpicks.
