Multiple companies manufacture original and replacement lawn mower blades varying in length and purpose, including Oregon, Fisher Barton Blades, Maxpower and Craftsman. Troy-Bilt also creates steel lawn mower blades.
Standard, gold metal and three-in-one blades are universal blades that include a 1 inch center hole and are manufactured by Maxpower. The gold metal universal blades from Maxpower feature a greater cutting area for increased mulching, sharper teeth for a cleaner cut and centrifugal air lift for uniform chopping distribution. For mowers with side-discharge, mulching, or bagging, Maxpower manufactures the universal three-in-one blades.
By converting steel into bainite, Fisher Barton Blades produces hard, nonbrittle lawn mower blades that are resistant to bending. Likewise, heat treatment is used by Oregon to produce consistently hard blades claimed to remain sharp. However, all universal blades manufactured by Oregon require adaptors specific for the lawn mower being used.
