Genuine OEM Toro 42" Timecutter Mulching Blade Part # 117-5376-03 Qty. 2

What It Is

This is a genuine OEM mulching blade set (2 blades) for Toro 42" TimeCutter zero-turn mowers. Designed to chop grass clippings finely and recirculate them into the lawn for natural fertilization, ideal for homeowners who want to avoid bagging.

Fitment & Compatibility

• Deck size: Fits only 42-inch TimeCutter decks (models like 74702, 74703, 74704, 74705, and similar).
• Brand/model: OEM Toro part, direct replacement for original blades on compatible TimeCutter models. Not for other brands or deck sizes.
• Check before buying: Measure your current blade length (should be ~20.5 inches), center hole diameter (1 inch), and thickness (0.2 inches). Confirm your deck has two blades (not three). Verify your model number on the Toro website or your owner’s manual.
• OEM vs aftermarket: OEM ensures exact fit, balance, and heat treatment. Aftermarket may be cheaper but can vary in quality and require balancing.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench, torque wrench (recommended 70-90 ft-lbs), and jack or blocks to lift the mower safely. Always disconnect the spark plug first.
• Mulching performance: These blades have a curved, high-lift design. They work best with the mulching baffle installed and when cutting no more than 1/3 of grass height at a time.
• Durability: Made of hardened steel, but hitting rocks or roots will dull them quickly. Inspect after heavy use or yearly.
• Common gotcha: Don’t overtighten—stripped blade bolts are a common repair. Use anti-seize compound on threads to prevent corrosion.

Should You Buy It

Yes, if you own a 42" Toro TimeCutter and want reliable, factory-matched mulching performance with no guesswork on fit. It’s a premium price for OEM quality, but avoids the hassle of balancing aftermarket blades or risking poor cut quality. Skip it if you need bagging or side-discharge blades—this set is strictly for mulching.
