The Fisher and Western 22275 is a genuine sno-foil assembly designed for the 7.5-foot, HD (Heavy Duty) series of Fisher plows. This steel deflector, a crucial part of the plow's blade, is designed to keep snow from rolling over the top of the plow. By redirecting snow back into the plowing path, it helps achieve a cleaner and more efficient clear, ultimately reducing your overall plowing time.
