Bell Blade Support Washer Replaces MTD 736-0524B

What It Is

A flat, hardened steel washer that sits between the blade and the deck spindle on many MTD-brand lawn mowers. It prevents the blade from seizing to the spindle and ensures proper torque distribution during blade installation.

Fitment & Compatibility

• Replaces OEM MTD 736-0524B – direct fit for most MTD, Cub Cadet, Troy-Bilt, and Yard Machines mowers using that part number.
• Check your deck size – common on 42", 46", and 50" decks, but not universal; verify your mower’s blade mounting system.
• Measure before buying – ID (inner diameter) ~0.531", OD ~1.375", thickness ~0.063". If your old washer matches these, it’s compatible.
• Aftermarket vs OEM – Bell’s is an aftermarket replacement, functionally identical to OEM. No mods needed.
• Not for all mowers – will not fit most Honda, John Deere, or Craftsman models with different spindle designs. Check your existing washer shape first.

Key Things to Know

• Quality – Made from hardened steel, resists deformation better than generic soft washers. Rated 4.7 stars across 419 reviews—users report no premature wear.
• Installation – Dead simple: remove blade bolt, slide old washer off, place new one on, reinstall blade and bolt. No special tools. Torque to 30-40 ft-lbs.
• Common gotcha – Some users find the ID slightly tight on older spindles with rust or burrs. Lightly file or sand the spindle if needed. Do not force it.
• Pack quantity – Sold as a single washer. If your mower uses multiple blades (e.g., 3-blade deck), you’ll need to buy separate packs for each.

Should You Buy It

If you own an MTD-family mower and need a reliable, inexpensive blade washer that won’t crush or warp under load, this is the right pick. It’s a no-brainer for routine blade swaps—just confirm your old washer matches the dimensions and you’re set.
