Replacement Blade for MTD 21" Mowers

This Stens Hi-Lift blade fits MTD 21-inch mowers manufactured from 1997 onward. It replaces OEM part numbers including Cub Cadet 742-04276 and MTD 942-0641. The blade is designed specifically for the bow-tie centre hole pattern found on these models. It is a direct replacement part for compatible decks.

Bow-Tie Centre Hole Installation

The bow-tie centre hole must align precisely with the spindle adapter on the mower deck. An incorrect match between the hole shape and the spindle is the most common reason the blade will not seat or secure properly. Verify the centre hole pattern on the original blade before fitting. No special tools are required beyond standard hardware for the outer mounting bolts.

21-Inch Cutting Length Specification

The 21-inch overall length determines whether this blade matches the cutting deck width. A blade that is too long or too short will not fit the deck housing or will leave an uncut strip. Confirm the original blade measures 21 inches tip to tip before ordering. Width and thickness are secondary to the length match.
