Keycci 490-110-C188 Toothed Mulching Blade, Compatible with Cub Cad et 60 inch Zero-Turn Mower ZT2-60 ZT3-60 ZTS2-60 Ultima Series, 742P05620-X Blade Replaces 742-05620, 3 Pack

What It Is

This is a set of three toothed mulching blades designed for 60-inch zero-turn mowers, specifically Cub Cadet Ultima Series models. They replace OEM part 742-05620 (742P05620-X) and are intended for fine grass clipping mulching and bagging.

Fitment & Compatibility

• Deck size: Only for 60-inch cutting decks. Do not use on 50-inch or 54-inch models.
• Model check: Fits Cub Cadet ZT2-60, ZT3-60, ZTS2-60, and all Ultima Series ZT models with a 60-inch deck. Also compatible with some RZT and Pro Z models using the same blade pattern.
• OEM cross: Replaces Cub Cadet 742-05620 and 742P05620-X. Always verify your current blade part number matches.
• Measurements: Blade length is 20.5 inches, center hole is 1 inch, and thickness is 0.204 inches. Measure your old blade to confirm.
• Aftermarket note: This is a third-party blade, not OEM. Fitment is good, but tolerances may differ slightly from factory blades.

Key Things to Know

• Installation: Easy with a socket wrench and blade removal tool (or block of wood). Torque bolts to 70-80 ft-lbs. Use new bolts if old ones are worn.
• Sharpness: Blades arrive sharp but may need light honing after first use. Mulching performance is strong on dry grass; wet grass may clog.
• Balance: Each blade is balanced from the factory, but it’s smart to check balance on a blade balancer before install to avoid vibration.
• Durability: Heat-treated steel holds up well for residential use. For heavy commercial mowing, expect faster dulling than OEM.

Should You Buy It

If you own a 60-inch Cub Cadet ZT2/ZT3/Ultima and want a budget-friendly mulching blade set that delivers clean cuts and good mulching action, this is a solid choice. It’s not for commercial abuse, but for home lawn care at $52.99 for three blades, the value is excellent.
