Overview

Upgrade your 21-inch push walk-behind mower with the Grasscool mulching blade. Designed to replace a range of common blade numbers, this blade aims to deliver a cleaner mulch bed and a balanced cutting performance on compatible Craftsman and Husqvarna decks. It features a circle-hole mounting pattern and is crafted to fit 21-inch decks, making it a practical swap for those who do their own lawn maintenance.

Key measurements and build details help you compare options at a glance: the blade runs 21 inches long, is 2-1/4 inches wide, and 5/32 inch thick, with an air lift of 1-1/8 inch.
