The only Blade System in the World manufactured to meet precise design tolerances incorporated into every Grasshopper DuraMax™ Deck. Austempered, boron steel heat treated to precise molecular structure and hardness is the backbone of a blade series that ensures superior cut quality, long life, minimal grass buildup and optimum airflow for side or rear discharge, mulching or collection. GrassMax™ blades are through-hardened to stay sharp longer (and survive more sharpenings) than the lesser case-only hardening found in throw-away aftermarket blades.
If cut quality and longer wear are important , make sure your blades have the Grasshopper logo!
