Oregon 11H is the fastest cutting 3/4" pitch harvester chain made today. The big semi-chisel cutters blaze through most woods quickly and effectively. Advanced chassis design helps reduce weight, dynamic loading, and wear while maintaining superior strength. Patented Oregon steel material and state-of-the-art manufacturing processes keep stretch and wear to a minimum, even while working in brutal cold-weather cutting conditions. 11H cutters also have a wide gullet and an offset footprint to minimize bar "knife-edging".
