42 Inch Mulching Mower Blades, Replaces 110-6568-03, 106-2247-03, 106-8744-03, 110-1857-03, 96-396, Compatible with Toro Timecutter 42 Inch Deck (2PCS)

What It Is

This is a set of two 42-inch mulching blades designed to replace OEM parts 110-6568-03, 106-2247-03, 106-8744-03, 110-1857-03, and 96-396. They’re intended for Toro Timecutter zero-turn mowers with a 42-inch deck, cutting grass into fine clippings that decompose quickly—no bagging required.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 42 inches (measure center-to-center of blade mounting holes). These blades are aftermarket replacements for specific Toro Timecutter models (e.g., SS4225, Z4200, Z4225) using the OEM numbers listed. Check your current blade’s part number—if it matches one of the five listed, these fit. Also verify the center hole diameter (typically 5/8-inch) and blade length (20.5 inches per blade). They will not fit other brands or non-Timecutter Toro decks without cross-referencing.

Key Things to Know

• Quality vs OEM: These are aftermarket blades, often slightly thinner or lighter than genuine Toro. Expect adequate mulching but potentially shorter lifespan under heavy use or rocky soil.
• Installation: Straightforward swap using a socket wrench and blade removal tool. Torque the mounting bolt to 70-90 ft-lbs. Always disconnect the spark plug first.
• Sharpening & Balance: New blades are sharp but may need balancing before install (use a blade balancer). Dull blades tear grass, leading to brown tips.
• Common Gotcha: The “42-inch” refers to the deck, not the blade length. Each blade is ~20.5 inches. Measure your existing blade length to avoid mismatch.

Should You Buy It

This is a solid budget option if you own a Toro Timecutter 42-inch deck and want to save over OEM pricing. It’s fine for typical residential lawn care, but if you mow frequently in tough conditions (wet grass, thick turf, or debris), consider spending more on factory Toro blades for longer durability and better cut quality.
