490-110-C188 Toothed Mulching Mower Blade Compatible with Cub Cad et 60" Cutting Deck, 742-05620 Heavt Duty Blade Compatibles with Cad ZT2-60, ZT3-60, ZTS2-60 Ultima Series Mowers, 3 Pack

What It Is

This is a 3-pack of toothed mulching blades designed for 60-inch cutting decks on Cub Cadet ZT2-60, ZT3-60, and ZTS2-60 Ultima Series zero-turn mowers. They replace OEM part 742-05620 and are intended for heavy-duty mulching, chopping clippings finer for better lawn nutrition.

Fitment & Compatibility

• Deck size: Only for 60-inch cutting decks. Measure your deck width before ordering—these will not fit 42", 48", 54", or 72" decks.
• Model fit: Confirmed for Cub Cadet ZT2-60, ZT3-60, ZTS2-60 Ultima Series. Not guaranteed for older Cadet models or non-Ultima series.
• OEM cross: Replaces Cub Cadet OEM part 742-05620. If your mower uses a different OEM number (e.g., 942-05620), check dimensions carefully.
• Measurements: Each blade is 20.5 inches long, 2.5 inches wide, with a 5/8-inch center hole and a 0.5-inch offset. Verify these against your current blade—especially the offset, which affects lift.
• Center hole: Standard 5/8-inch round; will not fit square-hole spindles.

Key Things to Know

• Toothed design: The serrated edge cuts grass rather than tearing it, producing finer mulch. Works best in dry grass; wet or tall grass may clog.
• Installation difficulty: Moderate. Requires a socket wrench and blade removal tool. Torque to 70–90 ft-lbs. Always lift the deck and disconnect the spark plug.
• Balance check: Aftermarket blades can be slightly off-balance. Spin-test each blade on a balancer before installing—unbalanced blades cause vibration and spindle wear.
• Durability: Heavy-duty steel, but toothed edges dull faster than standard blades. Expect to sharpen or replace after 25–30 hours of use on abrasive lawns.

Should You Buy It

Buy these if you own a Cub Cadet ZT2-60, ZT3-60, or ZTS2-60 Ultima mower and want finer mulching than standard blades provide. They’re a solid value for a 3-pack at $49.99, but skip them if you prefer a smooth cut for bagging or need OEM exactness—aftermarket fitment may require minor adjustments.
