With F Series Steel Tracks, your machine can handle even the toughest conditions. Designed primarily for mid-size skid-steer loaders and machines up to 120 horsepower with 10.00, 12.00, 14.00 or 15.50 tires; the F-Series features durable four-inch wide hammer-forged steel pads. They're engineered to be strong, long-lasting and self-cleaning. They're designed to reduce rutting and ground compaction. The F-Series is equipped with threaded dura pins for longer life and easier replacement than any other tracks. Each component is individually hardened for longevity and dependability. Extra-rugged construction results in a 2000-hour track life, based on average use.
