Chance Tree Trimmers are designed to cut up to 1.5 in dia. branches and are especially useful around energized conductors or in hard to get places. The Tree Trimmer head features sharpened stationary and movable blades made of dropforged steel. The rope and pulley arrangement gives the operator a mechanical advantage of 3 to 1. For example, a 10-lb. pull on the rope will exert a 30-lb. force on the cutter head lever. Ball bearing pulleys are employed for free operation. The rope furnished with each tree trimmer is 25 ft long, which will accommodate a 6 ft extension on the basic tool.
