Lawn Mower Mulching Blades
Mulching blades cut and recirculate clippings so the finish is finer and bagging is reduced. The profile has to hold its edge through repeated impact with grit and stones — which is a material and heat-treatment problem before it is a geometry problem.
Short answer: MowForge mulching blades are replacement mower blades in 40Mn manganese steel at 45–50 HRC, shaped to recirculate clippings for a finer finish and less bagging. They are made to match the original specifications, ship from 300 pcs, and go direct from our factory to dealers, contractors and OEM brands.
