MTD Replacement Part 14.88 Long 3-in-1 Blade

What It Is

This is a genuine MTD 3-in-1 lawn mower blade, 14.88 inches long, designed for mulching, bagging, and side-discharge. It’s intended for use on select MTD, Cub Cadet, Troy-Bilt, and Yard Machines walk-behind mowers.

Fitment & Compatibility

Before buying, verify three things:

• Blade length: Must be exactly 14.88 inches (measured from tip to tip). Measure your old blade or your deck’s blade span. This blade fits decks requiring a 14.88” or 15” blade (common on 42cc–140cc push mowers).
• Center hole: This blade has a 1-inch diameter center hole with a 5-point star pattern. Confirm your mower’s spindle matches this star drive – it won’t fit standard round hole or 2-point keyed spindles.
• Model number: Cross-reference your mower’s model number with MTD part 742-0600A (OEM). This is a genuine MTD replacement, not an aftermarket universal blade. It fits many MTD, Cub Cadet, Troy-Bilt, Yard Machines, and Craftsman (with MTD deck) models from the 2000s onward. Check your owner’s manual or current blade part number.

Key Things to Know

• Quality: Genuine MTD steel, pre-sharpened, and balanced. Expect 2–3 seasons of typical residential use before dulling.
• Installation: Easy – one bolt per blade. Use a torque wrench to 35–45 ft-lbs. Always lift/block the mower and disconnect the spark plug for safety.
• Common gotcha: This blade is 14.88”, which is slightly shorter than the common 15” or 16” blades. Do not substitute a longer blade – it can hit the deck or cause vibration. Measure twice.
• 3-in-1 versatility: Works for mulching, bagging, and side-discharge. No need to swap blades for different cutting modes.

Should You Buy It

Buy this if you need a direct OEM replacement for a 14.88” star-drive MTD blade on a walk-behind mower. It’s a solid choice for reliable performance and easy installation. Skip it if your mower uses a different blade length, center hole, or spindle pattern – you’ll need to match those specs exactly.
