Mr Mower Parts Lawn Mower Blade 22" Cut Deck Compatible with MTD Cub Cadet 742-0742, 742-0742A, 942-0742, 942-0742A, 7420742, 7420742A, 9420742, 9420742A OEM Replacement

What It Is

This is a 22-inch replacement blade designed for MTD and Cub Cadet walk-behind mowers with a 22-inch cutting deck. It directly replaces OEM part numbers 742-0742, 742-0742A, 942-0742, 942-0742A, and their numeric-only variants, making it a drop-in fit for many standard residential mowers in these brands.

Fitment & Compatibility

Before buying, confirm three things:

1. Deck size: Your mower must have a 22-inch cutting deck. Measure from blade tip to blade tip (with the old blade removed) or check the deck sticker.
2. OEM cross-reference: This blade matches MTD/Cub Cadet part numbers listed above. Check your owner’s manual or existing blade for one of these numbers. If your mower uses a different OEM number (e.g., 942-0742B), it may not fit.
3. Center hole and drive type: This blade uses a 5-point star center hole. Verify your spindle matches this pattern—common on most MTD/Cub Cadet single-blade 22" decks. If your spindle uses a round hole or different star pattern, this blade won’t work.

Key Things to Know

• Build quality: Aftermarket blade at a lower price than OEM, but reviews note it’s slightly thinner than the original. It may wear faster on heavy-duty or frequent use.
• Installation: Easy DIY—remove the old blade, center the new one on the spindle, and torque the bolt to 30-40 ft-lbs. Use a blade removal tool or wedge to lock the blade.
• Common gotcha: The blade is 22 inches tip-to-tip, but some OEM replacements are labeled as 22.25 inches. Double-check your deck measurement to avoid a blade that’s too long or too short.
• Balance: Aftermarket blades often require balancing. Check with a blade balancer before installing to avoid vibration and spindle wear.

Should You Buy It

Buy this blade if you have a standard 22-inch MTD or Cub Cadet mower and want a budget-friendly replacement that fits correctly. It’s ideal for light-to-medium residential use. Skip it if you need a heavy-duty, thicker blade for rough terrain or frequent mowing—consider OEM or a premium aftermarket brand instead.
