While many aftermarket blades list these part numbers as a cross-reference, Atom Industries officially warns that using non-genuine blades can void your warranty. They note that third-party blades are often heavier or thicker, which can lead to gear system damage because they don't absorb shock as well as the genuine flexible steel blades.
