What It Is

This is a set of 50-inch mulching blades designed for Toro TimeCutter zero-turn mowers. They replace OEM part numbers 115-5059-03 and 110-6837-03, and are intended for use on 50-inch cutting decks that require a mulching action to finely chop clippings for nutrient recycling.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 50 inches wide—measure from outside blade tip to outside tip. These blades fit Toro TimeCutter models SS5000, MX5050, MX5000, MX5075, Z5000, and 70750. They are aftermarket replacements, not OEM Toro parts, so check that your existing blades are 115-5059-03 or 110-6837-03. Verify blade length (approx. 20.5 inches), center hole diameter (1 inch), and thickness (0.25 inch) to match your spindles. Do not assume fit across all 50-inch Toro decks—cross-reference your model number with the seller’s list.

Key Things to Know

• Mulching vs. standard: These blades have a curved, high-lift design to recirculate clippings. They work best with a mulching plug or baffle kit installed; without it, performance drops.
• Installation difficulty: Moderate—requires a socket wrench, torque wrench (set to 70–90 ft-lbs), and safety blocks. Lift the deck, remove the old blades, and install with the cutting edge facing the direction of rotation (usually upward toward the deck).
• Balance check: Aftermarket blades may need balancing before first use. Use a blade balancer; if one side dips, file the heavy end slightly.
• Sharpness out of box: Many users report they are sharp but not as durable as OEM. Expect to sharpen after 10–15 hours of use, especially in thick or wet grass.

Should You Buy It

These are a budget-friendly alternative to OEM blades for Toro TimeCutter owners who mow frequently and want fine mulching. They fit well on listed models, but if you need maximum longevity or have a non-standard deck, stick with genuine Toro parts. Good for cost-conscious users who don’t mind periodic sharpening.
