What It Is

The fascinatte 748-0376E is a lawn mower blade adapter that connects the blade to the crankshaft on push mowers and riding mowers. It’s designed for MTD, Murray, and Troy-Bilt machines that use a 25mm (0.984-inch) diameter center hole and a 5-point star pattern.

Fitment & Compatibility

Before buying, check three things:

• Crankshaft diameter – Must be 25mm (about 1 inch). Measure yours with a caliper; a 7/8-inch shaft won’t fit.
• Star pattern – This adapter uses a 5-point star (often called “5-lobe” or “5-point”). Count the lobes on your current adapter.
• OEM cross-references – Replaces MTD 748-0376, 748-0376A, 748-0376B, 748-0376C, and Oregon 15019. Fits many MTD, Murray, Troy-Bilt, Yard-Man, and Yard Machines models with 25mm crankshafts.

Not compatible with 7/8-inch shafts or 4-point/6-point star patterns. Verify your deck size isn’t the only spec—deck width alone doesn’t guarantee fit.

Key Things to Know

• Quality concerns – Some users report the adapter is slightly softer metal than OEM, which can wear faster under heavy use or if blade bolts are over-tightened.
• Installation difficulty – Easy swap if you have a socket wrench and a block of wood to lock the blade. No special tools needed.
• Common gotcha – The adapter may sit slightly higher or lower than OEM, causing blade alignment issues. Check blade clearance after installation—if it hits the deck housing, return it.
• Torque matters – Follow your mower’s torque spec (usually 35–50 ft-lbs). Overtightening can deform the adapter or strip the crankshaft threads.

Should You Buy It

Buy this if you need a budget-friendly replacement for a 25mm, 5-point star adapter and your mower is a common MTD/Murray/Troy-Bilt model. It’s fine for occasional residential use but may not hold up as long as OEM under frequent or heavy-duty mowing. If you mow tough terrain or run a commercial machine, stick with OEM MTD or Oregon parts for better durability.
