942-0742 One Aftermarket Mulching Mower Blade Fits MTD Fits Yardman 22" Mower

What It Is

This is an aftermarket mulching blade designed for 22-inch MTD and Yardman walk-behind mowers. It replaces the OEM part 942-0742 and is intended for mulching—cutting grass into fine clippings that decompose into the lawn.

Fitment & Compatibility

Before buying, confirm three things:

1. Deck size: This blade fits only 22-inch cutting decks. Measure your mower deck width if unsure.
2. Model/brand: Fits most MTD and Yardman mowers using a 942-0742 OEM blade. Check your mower’s model number or existing blade part number. It may also fit some Troy-Bilt, Cub Cadet, or Craftsman models that share the MTD platform.
3. Measurements: The blade is 22 inches long with a center hole diameter of 1 inch and a 5-point star center. Verify your blade’s length, center hole shape, and thickness (typically 0.25 inches). If your blade has a different center hole (e.g., diamond or oval), this will not fit.

Key Things to Know

• Quality: Aftermarket blades are often thinner or less balanced than OEM. Expect slightly shorter life and more vibration if not properly balanced.
• Installation: Easy—remove the old blade (use a block of wood to lock the blade), install the new one with the sharp edge facing upward (mulching blades are reversible). Torque the bolt to 30–50 ft-lbs. Do not over-tighten.
• Mulching vs. bagging: This blade is designed for mulching only. If you frequently bag or side-discharge, consider a universal blade instead.
• Balance: Always check blade balance after installation. An unbalanced blade causes vibration, poor cut quality, and can damage the spindle. Use a blade balancer tool or a nail in the wall.

Should You Buy It

Buy this if you have a 22-inch MTD or Yardman mower, want a budget-friendly replacement for mulching, and are comfortable with a quick DIY install. Skip it if you need a blade for bagging or side-discharge, or if you prefer OEM quality for longer life and smoother operation.
