This is a set of 21-inch mulching blades designed for MTD, Cub Cadet, and Troy-Bilt walk-behind mowers with a 21-inch cutting deck. The blades recut grass clippings into fine particles for nutrient return to the lawn.
Fitment & Compatibility
Before buying, confirm three things: (1) your mower deck measures exactly 21 inches across; (2) your mower model is on the compatible list (e.g., Troy-Bilt TB130, TB210, Cub Cadet CC999ES, SC500E, or similar MTD-platform models); (3) the blade dimensions match—center hole diameter is 1 inch, blade thickness is 0.25 inches, and the drive pin holes align. This is an aftermarket replacement for OEM part numbers 742-0741A and 942-0741. If your mower uses a different blade length or a 5-point star center hole, these won’t fit. Check your owner’s manual or measure your current blade before ordering.
Key Things to Know
- Quality: Blades are heat-treated steel with a painted finish. They are generally durable for residential use but may be slightly thinner than OEM blades.
- Installation: Easy to swap with basic tools (socket wrench, blade removal tool or block of wood). Torque the blade bolt to 35-40 ft-lbs—overtightening can strip the bolt or damage the spindle.
- Gotcha: These are mulching blades, not high-lift or bagging blades. They won’t throw clippings far into a bagger—expect finer clippings left on the lawn.
- Pack size: This listing is for 1 blade, not a set. Most mowers require two blades (one for the left, one for the right). Verify your deck uses a single blade or order two.
Should You Buy It
Buy these if you need a budget-friendly replacement mulching blade for a 21-inch MTD/Cub Cadet/Troy-Bilt mower, you’re comfortable with basic maintenance, and you don’t require OEM branding. Skip them if you need bagging blades, have a different deck size, or want the absolute thickest steel for heavy commercial use.
