Grasscool Circle-Mount Mulching Blade for 21-Inch Decks

Upgrade your lawn routine with Grasscool’s 21-inch mulching blade, designed for Craftsman and Husqvarna push walk-behind mowers. This blade uses a circle mounting pattern for a secure, stable fit, helping you achieve even clippings and a neat, natural look after every pass.

Key benefits at a glance

• Circle-hole mounting pattern for quick, confident installation and steady performance on compatible decks.
• Mulching design reshapes clippings into finer material and returns nutrients to the lawn without requiring extra steps.
• Compatible with multiple replacement numbers, including 165833, 175064, 189028, 406712, 532175064, 532165833, 532189028, and 532406712.
• Solid construction with the right balance for 21-inch decks: 21" (534mm) length, 2-1/4" (57mm) width, 5/32" (4mm) thickness, air lift 1-1/8" (28mm).

What to know before you buy

• Two common mounting patterns exist for 21" mowers. If your blade uses a Bow Tie center hole, you’ll want a different MPN (942-0741A) from Grasscool or a partner source.
• The blade ships with a protective paint layer intended to prevent rust during handling; the coating may wear off after initial use, revealing the underlying blade finish.
• Always compare the replacement number, model, and size with your mower’s original blade to ensure a proper match.

Real-world use and expectations

Imagine mowing on a sun-warmed afternoon, watching finely mulched clippings feed the soil rather than piling up. The Grasscool blade is built to balance cutting performance with efficient mulch return, which can help reduce cleanup time and promote a tidier lawn edge. While individual results vary with mower condition and grass type, many users notice improved mulching consistency and steady cutting rhythm on 21-inch decks.

Designed to fit a range of popular models, this blade is a practical upgrade for seasonal mowing, garden edging days, and regular maintenance when you want dependable mulching without frequent blade changes. It’s a clear option for homeowners seeking a practical blend of reliability, performance, and ease of use, without overpromising outcomes.
