21 Inch Mulching Blades — Gator-Style

High-lift blades excel at bagging or side-discharging clippings by generating strong airflow to propel material out of the deck. Mulching blades — especially gator-style toothed designs — are superior when you want clippings recycled back into the lawn. For flail mower applications in vegetation management, mulching-style blades provide better material breakdown and reduced debris spread.

For mulching leaves, set your mower deck to a mid-range height — typically 3 to 3.5 inches. This keeps enough distance between the blade and ground for adequate airflow while allowing multiple passes over leaves. Gator-style mulching blades with serrated teeth further pulverize leaf matter into fine particles that decompose rapidly into the lawn.

Toothed or gator-style mulching blades work better than standard mulching blades for heavy debris, thick clippings, and leaf mulching. The serrated teeth create additional cutting edges that re-cut material multiple times before discharge. Clean Cutter's hard-faced and Super-Koat blade options ensure these teeth retain sharpness far longer in abrasive operating conditions.

Choose Plain grade for standard light-duty use, Hard-Faced blades for moderately abrasive conditions — offering twice the life of plain blades. For highly abrasive soils or rocky terrain, Super-Koat heat-treated blades provide three or more times the service life of plain blades, significantly reducing replacement frequency and labor costs.
