(2) Toothed Mulching Mower Blades Fits Toro Timecutter 42" Deck Replaces 110-6568-03

What It Is

This is a set of two toothed mulching blades designed for the Toro Timecutter 42-inch zero-turn mower. They replace OEM part number 110-6568-03 and are intended for mulching grass clippings into fine particles that decompose quickly.

Fitment & Compatibility

• Deck size: 42 inches (fits Toro Timecutter models with a 42″ fabricated deck only – not 42″ stamped decks).
• OEM part cross-reference: Replaces Toro 110-6568-03, 110-6568-04, and 110-6568-05.
• Measurements: Blade length is 16.5 inches, center hole diameter is 5/8 inch, and blade thickness is 0.204 inch. Confirm your existing blade matches these dimensions.
• Models: Compatible with Toro Timecutter SW4200, SWX4200, SS4225, and similar 42" zero-turn models. Check your mower’s model number (on the frame or under the seat) against Toro’s compatibility list.
• Note: These are not for Toro 42" Timecutter models with a “SmartStow” deck or older 42" Timecutter units with a different blade mount pattern.

Key Things to Know

• Quality: Aftermarket blades, not OEM Toro. Some users report they are slightly thinner (0.204″ vs OEM 0.210″) and may wear faster in heavy use or rocky soil.
• Installation: Easy – remove the old blade, install new one with the toothed edge facing the deck. Use a torque wrench; tighten to 50-60 ft-lbs. The blades are not reversible (only one sharp edge).
• Balance: Check blade balance before mounting. Some units arrive unbalanced, which causes vibration and deck damage. A simple blade balancer is cheap insurance.
• Mulching performance: The toothed design chops clippings finer than standard lift blades, but works best with dry grass. Wet or tall grass will clog the deck faster.

Should You Buy It

Buy these if you have a Toro Timecutter with a 42″ fabricated deck and want an affordable mulching upgrade over standard blades. They are a good value for occasional residential use, but skip them if you mow commercially, need OEM durability, or have a stamped deck.
