748-0376E 753-06315 710-1044 Lawn Mower Blade Adapter Kit for MTD

What It Is

This blade adapter kit (748-0376E, 753-06315, 710-1044) replaces the center mounting hub that connects the blade to the crankshaft on MTD-brand walk-behind mowers. It’s designed for mowers with a 7/8-inch diameter, 6-point star-shaped crankshaft output.

Fitment & Compatibility

Before buying, confirm your mower uses a 7/8-inch, 6-point star crankshaft (not a round or 5-point shaft). This kit fits most MTD, Cub Cadet, Troy-Bilt, Yard Machines, and Yard-Man models with a 7/8" star drive. Check your mower’s model number (under the seat or on the deck) against the OEM part numbers: MTD 748-0376E, 753-06315, or 710-1044. It’s a direct aftermarket replacement for these OEM parts. Measure your old adapter’s center hole diameter and star pattern—if it’s 7/8" across the flats, this kit is likely correct. Not for 1-inch or 5/8-inch shafts.

Key Things to Know

• Includes three pieces: The adapter, a center bolt (710-1044), and a key/washer—verify you have all before starting.
• Installation is straightforward: Remove the old blade and adapter, clean the shaft, slide the new adapter on, torque the bolt to 30-40 ft-lbs. Use thread locker if recommended.
• Common gotcha: The adapter can seize to the shaft over time. Apply anti-seize to the shaft and bolt threads to ease future removal.
• Quality note: Aftermarket, not OEM. Some users report slightly looser fit on the star pattern, but it works fine for residential use. Check for burrs or casting flash before install.

Should You Buy It

If you have an MTD-family mower with a 7/8" star shaft and your old adapter is worn, stripped, or missing, this kit is a no-brainer at $13.29. It’s a simple, reliable fix for a common failure point. Avoid it if you need OEM-specific tolerances for commercial use—spend more on genuine MTD.
