Mulching Blades 21 in for Troy Bilt 942-0741A TB130 TB240 - 2 Pack

In this review of the Mulching Blades 21 in for Troy Bilt 942-0741A TB130 TB240, the bottom line is straightforward: these replacement blades are aimed at homeowners and small property owners who need a reliable, direct-fit blade that offers clean cutting and easy installation. The reviewer found the blades to be a practical, value-oriented replacement that fits a wide range of Troy Bilt, Craftsman, MTD and Cub Cadet decks and restores cutting performance quickly; the single biggest reason to buy is the combination of correct OEM fitment and ready-to-run edge that reduces setup hassle.

Key Features

• Exact dimensions: 21 in length measured diagonally and a 2-1/4 in width ensure the blade matches the specified 21 in deck size so replacement is straightforward.
• OEM compatibility: Replaces multiple OEM part numbers including 942-0741A and 742-0741A, so it fits many Troy Bilt, Craftsman and MTD machines without modification.
• Mounting pattern: Bow-tie center hole with 5/16 in side hole and 2-1/2 in center to center outside hole provides correct alignment for secure installation.
• Durable profile: 0.126 in thickness and 6-7/64 in cutting edge length offer a sturdy blade that resists bending under typical homeowner loads.
• Pre-sharpened safety finish: Cutting edges are pre-sharpened and painted over for safe handling, and the paint wears off quickly during initial use.

Who It's For

These blades are best for owners of walk-behind mowers with a 21 in deck who need a like-for-like replacement for OEM 942-0741A and related part numbers. They suit homeowners who want a straightforward swap to restore cutting performance, and anyone who values correct mounting holes and a pre-sharpened edge that reduces installation fuss.

They are less appropriate for users seeking specialized high-performance mulching blades with aggressive mulching fins or for commercial operators who demand hardened, long-wear alloys beyond typical homeowner duty. Verify the full model number on the mower before purchase to ensure a proper fit.
