Mower Mulching Blades for TimeCutter 42" Decks Replacement for 117-5376-03 with Bolts and Washers 2 PCS

What It Is

This is a set of two aftermarket mulching blades designed for Toro TimeCutter 42-inch zero-turn mowers. They replace OEM part number 117-5376-03 and include bolts and washers, intended for cutting grass into fine clippings that decompose quickly on the lawn.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Must be a 42-inch cutting deck. Measure your deck width if unsure—TimeCutter models also come in 50" and 60" decks.
• Model range: Fits Toro TimeCutter 42" models from 2013 onward (e.g., SS4225, MX4200, SW4200). Also compatible with some Toro Titan 42" and GrandStand 42" models, but verify your mower’s blade spindle pattern.
• Measurements: Each blade is roughly 20.5 inches long, 2.5 inches wide, with a 1-inch center hole and a 5-point star drive pattern. OEM 117-5376-03 blades are identical. Aftermarket blades may vary slightly in thickness or balance—check for warping or uneven edges on arrival.

Key Things to Know

• Installation difficulty: Easy (30 minutes or less). Remove the mower deck, block it safely, use a socket wrench to swap blades. Torque bolts to 70–90 ft-lbs.
• Mulching performance: These blades have a higher lift and curved design to recirculate clippings. Works best with dry grass—wet grass clumps and reduces mulching quality.
• Common gotcha: The included bolts and washers are standard 5/16-18 thread, 1.5-inch length. If your mower uses a different bolt size (rare on TimeCutters), reuse your original hardware.
• Quality variance: At $23.99 for two blades with hardware, this is a budget option. Expect shorter lifespan than OEM (maybe 25–30 hours of use) due to lower-grade steel. Check for bent tips after hitting rocks or roots.

Should You Buy It

Buy this if you have a Toro TimeCutter 42" deck, want an affordable mulching upgrade, and are comfortable with basic DIY installation. It’s a solid value for light-to-moderate use, but if you mow large, rough lawns or need maximum durability, stick with OEM 117-5376-03 blades.
