High-lift blades are great for getting a clean cut.  The sail, or 'fin,' on these blades create lift like air plane wings or helicopter propellers that suck the grass upward as it is cut for a flush, even appearance after mowing.

Mulching blades are perfect if you like to return your clippings to the lawn.  Please note if you mow frequently enough, you can return clippings to the lawn using high-lift blades!  We have 2 styles of mulching blades available including a wavy blade version and a serrated sail version.
