What It Is

This is a 3-pack of aftermarket mulching blades designed for 50-inch deck Toro TimeCutter zero-turn mowers. They replace OEM part numbers 115-5059-03, 112-9759-03, 74370, and 74372, and are intended for fine grass clipping mulching rather than bagging or side-discharge.

Fitment & Compatibility

• Deck size: 50 inches only. Will not fit 42", 54", or 60" TimeCutter decks.
• Models: Toro TimeCutter Z5000, MX5050, MX5000, MX5060, MX5075, SS5000, SS5060. Check your model’s serial number against Toro’s deck compatibility list.
• OEM vs aftermarket: These are aftermarket blades, not genuine Toro. They may have slightly different balance or steel thickness. Verify the center hole diameter (likely 1") and blade offset match your originals.
• Measure before ordering: Remove one existing blade and compare length (approx. 20.5"), width, and thickness. A mismatch can cause vibration or poor cut.

Key Things to Know

• Installation: Requires a torque wrench. Toro spec is 70–80 ft-lbs. Over-tightening strips the spindle threads. Use a blade removal tool or block of wood to lock the blade.
• Mulching performance: The curved design and extra cutting edges work well for dry grass. Wet or tall grass may clog—stick to 1/3 rule (cut no more than 1 inch per pass).
• Quality control: Check each blade for burrs or uneven edges before mounting. File down any sharp spots to reduce vibration and extend spindle bearing life.
• Balance: Aftermarket blades are less likely to be pre-balanced. After installation, spin the deck by hand—if you feel wobble, swap blade positions or replace the set.

Should You Buy It

If you have a 50-inch TimeCutter and primarily mulch dry, maintained grass, this 3-pack offers solid value at $31.99. It’s a good budget alternative to OEM blades for routine replacements, but skip it if you need bagging or side-discharge performance, or if your deck requires exact OEM balance for a vibration-free cut.
