490-110-C188 Mulching Toothed Blades 60 inch Mower Deck Fit for 742-05620 742P05620 MTD Cub Cadet ZT2-60 ZT3-60 ZTS2-60 (3 Pack)

What It Is

This is a set of three mulching blades with toothed cutting edges, designed to replace OEM part 742-05620 (742P05620) on 60-inch mower decks. They’re built for Cub Cadet ZT2-60, ZT3-60, and ZTS2-60 zero-turn mowers, but also fit other MTD/Cub Cadet models with the same blade pattern.

Fitment & Compatibility

• Deck size: 60 inches (requires 3 blades).
• OEM cross-reference: Directly replaces 742-05620 and 742P05620.
• Measurements: Blade length is 20.5 inches, center hole diameter is 5/8 inch, with a 0.25-inch thickness. Verify your existing blade matches these specs.
• Brand fit: Cub Cadet (MTD) only—not compatible with John Deere, Husqvarna, or other brands unless they use the same OEM blade pattern.
• Check before buying: Confirm your deck uses three blades (not two) and that your spindle center pin is 5/8 inch. Measure your current blade length and hole size.

Key Things to Know

• Mulching vs. side-discharge: These blades produce finer clippings for mulching; they won’t perform as well for bagging or side-discharge.
• Installation: Straightforward—remove the old blade, note washer/bolt orientation, and torque to 70–90 ft-lbs. Use a blade lock or wedge to prevent spinning.
• Sharpness out of box: They’re factory-sharp but may need a touch-up for optimal cut on thick grass. Resharpen after 25 hours of use.
• Common gotcha: The toothed edge can catch debris if you mow wet or overgrown grass—keep blades clean to avoid vibration.

Should You Buy It

If you own a Cub Cadet ZT2-60, ZT3-60, or ZTS2-60 with a 60-inch deck and want a durable, OEM-fit mulching upgrade at a lower price than dealer blades, this 3-pack is a solid choice. It’s ideal for homeowners who primarily mulch and want fine clippings without switching to side-discharge.
