942-0741A Mulching Blade Fits for Craftsman 21" Deck, 942-0741 Mower Blades for Troy Bilt TB130 TB230 410 Craftsman 247 Series Push Mower, SC700E Self Propelled, 2 Pack

What It Is

This is a 2-pack of mulching blades designed to fit 21-inch Craftsman, Troy-Bilt, and compatible push mower decks. The “mulching” design recirculates grass clippings into fine particles that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, verify three things:

1. Deck size – Must be exactly 21 inches. Measure your mower deck’s cutting width if unsure.
2. Model/brand – Fits Craftsman 247 series, Troy-Bilt TB130/TB230/TB410, and SC700E self-propelled models. Also fits many Craftsman push mowers originally using OEM part 942-0741 or 942-0741A.
3. Blade measurements – Each blade is 21 inches long, with a 1-inch center hole and a 0.25-inch thickness. Measure your old blade’s length and center hole diameter to confirm. If your mower uses a different hole size (e.g., 7/8-inch star or 5-point), this blade won’t fit.

OEM vs aftermarket: This is an OEM Craftsman replacement, not a generic. It matches factory specs for durability and balance.

Key Things to Know

• Installation difficulty: Easy – requires a socket wrench and a block of wood to wedge the blade. Torque the center bolt to 30-40 ft-lbs.
• Mulching performance: Works best with dry, short grass. Wet or tall grass may clump. Keep mower speed moderate.
• Common gotcha: The blade is stamped steel, not hardened. It will dull faster on rocky or sandy soil. Replace after ~25 hours of use or when cutting quality drops.
• Balance check: Always spin the blade on a balancer after installation. An unbalanced blade causes vibration and can damage the spindle.

Should You Buy It

If you own a compatible Craftsman or Troy-Bilt 21-inch push mower and want to mulch rather than bag, this OEM 2-pack is a solid, affordable choice. It’s best for homeowners with standard lawns (not rocky or overgrown) who value convenience and a clean, fertilizer-free cut.
