742P05620-X Mulching Mower Blades Set for Cub Cadet Craftsman MTD Troy Bilt 60" Zero-Turn Mower, Replaces 742-05620-X, Compatible with Ultima ZT2-60 ZT3-60 ZTS2-60 (3PACK)

What It Is

This is a 3-pack of mulching blades for 60-inch zero-turn mowers from Cub Cadet, Craftsman, MTD, and Troy-Bilt. They’re designed to cut grass into fine clippings that decompose quickly, eliminating the need to bag or rake.

Fitment & Compatibility

Before buying, confirm three things:

1. Deck size: These blades fit only 60-inch cutting decks. Measure your deck width or check your mower’s model number (e.g., Ultima ZT2-60, ZT3-60, ZTS2-60).
2. OEM part number: They replace OEM blade 742-05620-X. Check your current blade’s part number (stamped on the blade or in your manual). If it matches, these will fit.
3. Physical dimensions: Each blade is 20.5 inches long with a 5-point star center hole and 0.25-inch thickness. Measure your existing blade length and center hole shape—if they match, you’re good. These are not universal; they won’t fit non-MTD/Cub Cadet/Craftsman/Troy-Bilt decks.

Key Things to Know

• Mulching vs. regular blades: These have a curved, serrated edge that recirculates clippings. They produce finer cut than standard lift blades but may require slower mowing in tall or wet grass.
• Installation: Easy if you have a socket wrench and a blade removal tool (or block of wood to jam the blade). Torque to 70–90 ft-lbs. Do not overtighten.
• Sharpness: Blades come sharp but not edge-ready—they’ll need a quick hone after the first few hours to maintain performance. Dull mulching blades tear grass, causing brown tips.
• Common gotcha: These are not for side-discharge or bagging setups. If you switch between mulching and bagging, you’ll need a separate set of lift blades.

Should You Buy It

Buy this if you own a 60-inch Cub Cadet, Craftsman, MTD, or Troy-Bilt zero-turn mulching deck and want OEM-quality replacement blades at a fair price. It’s ideal for homeowners who mow weekly and prefer fine clippings over bagging. Skip it if you need side-discharge or bagging blades, or if your deck uses a different blade length or center hole pattern.
