106-2247-03 106-8744-03 Mulching Mower Blade, Compatible with T oro TimeCutter Z420 Z4200 Z4202 ZS4200 ZS4202 Z530 42-Inch Cutting Deck Lawn Mower, Replace 110-6568-03 110-1857-03, 2 Pack

What It Is

This is a 2-pack of aftermarket mulching blades designed for 42-inch cutting decks on Toro TimeCutter zero-turn mowers. They chop grass clippings into fine pieces to return nutrients to the lawn, ideal for frequent mowing without bagging.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck and is one of these models: Toro TimeCutter Z420, Z4200, Z4202, ZS4200, ZS4202, or Z530. These blades replace OEM part numbers 110-6568-03 and 110-1857-03. Measure your existing blade: center hole diameter should be 1 inch (some Toro decks use a 7/8-inch hole—verify yours). Check blade length: 18 inches tip-to-tip. If your deck is 42 inches but uses a different blade design (e.g., with a different center hole or offset), these won’t fit. Also confirm your mower uses two blades (some 42-inch decks use three).

Key Things to Know

• Quality: Aftermarket steel—likely adequate for residential use but may dull faster than OEM Toro blades. Inspect for balance before installing (hang on a nail or use a balancer).
• Installation: Straightforward with a socket wrench. Use a blade removal tool or wedge to lock the spindle. Torque bolts to 50-60 ft-lbs—don’t overtighten.
• Mulching performance: These blades have a curved, cupped shape to recirculate clippings. They work best with a high-lift deck and sharp blades. Dull blades tear grass, causing brown tips.
• Common gotcha: The 2-pack may include one blade with a slight offset difference—check both match your deck’s spindle orientation (some Toro decks require LH and RH blades).

Should You Buy It

Buy this if you need a budget-friendly, direct-replacement mulching blade for a Toro TimeCutter 42-inch deck and you’re comfortable with aftermarket consumables. Skip it if you mow commercially, want OEM durability, or have a different deck size or spindle design. For $25.99, it’s a decent stopgap but not a long-term upgrade.
