106-2247-03 Mulching Mower Blades Kit Compatible with 42" Deck to-ro Time Cutter Z420 Z4200 Z4202 ZS4200 ZS4202 Z530 Lawn Mowers，Replace110-1857-03，2 Pack

What It Is

This is a 2-pack set of mulching blades designed for 42-inch cutting decks on select Toro TimeCutter zero-turn mowers. They replace OEM part 110-1857-03 and are intended for fine-clipping mulching, not bagging or side-discharge.

Fitment & Compatibility

• Deck size: 42 inches. Measure your deck width; this will not fit 44", 46", or 50" decks.
• Models: Toro TimeCutter Z420, Z4200, Z4202, ZS4200, ZS4202, Z530. Verify your model number on the mower frame tag, not just the series name.
• OEM cross-reference: Replaces Toro 110-1857-03. Aftermarket, not OEM—check that the blade hole pattern (center hole, star, or oval) matches your spindle.
• Measurements: Blade length should be ~21 inches (center hole to tip). Confirm with a ruler before installing.

Key Things to Know

• Installation: Easy swap with a socket wrench and blade removal tool. Torque spindle bolts to 45–55 ft-lbs. Use thread locker if bolts are loose.
• Mulching performance: These blades have a higher lift and more cutting edge than standard blades. They chop clippings finer but may leave clumps in wet grass—mow dry.
• Quality: Aftermarket steel, not heat-treated like OEM. Expect slightly shorter lifespan, especially in sandy or rocky soil. Inspect for bends or dull edges after heavy use.
• Gotcha: Some users report the center hole is slightly tight on the spindle. File or sand lightly if needed—do not force it or you risk stripping the bolt.

Should You Buy It

If you own a compatible 42" Toro TimeCutter and want an affordable mulching upgrade for dry-season grass, this kit works well. Skip it if you need OEM durability for rough terrain or frequent wet mowing—spend more on genuine Toro blades.
