What It Is

This is a set of three high-lift lawn mower blades designed to replace OEM parts on specific Toro zero-turn mowers with a 50-inch cutting deck. High-lift blades create stronger airflow to improve grass clipping discharge into the bagger or out the chute, making them ideal for mulching or collecting leaves and tall grass.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch deck and is one of these models: Toro TimeCutter SS5000 (75750), MX5000 (75755), MX5060, MX5050, SWX5050, or 74731. These blades replace OEM part numbers 110-6837-03 and 112-9759-03. Measure your existing blade length—these are 20.5 inches long with a 1-inch center hole and a 0.25-inch thickness. They will not fit 42-inch, 54-inch, or 60-inch decks, nor non-Toro brands without adapter plates.

Key Things to Know

• Installation difficulty: Easy to moderate. You’ll need a socket wrench and a torque wrench (recommended 70–90 ft-lbs). Always disconnect the spark plug first.
• High lift = more power draw: These blades require more engine power than standard blades. If your mower bogs down in thick grass, raise the deck height or mow slower.
• Balance check: New blades can be slightly unbalanced out of the box. Use a blade balancer before installing to prevent vibration that damages the spindle.
• Sharpness: They come sharp but not razor-edged. For best cutting, sharpen after 10–15 hours of use.

Should You Buy It

This set is a solid choice if you own one of the listed Toro 50-inch zero-turn models and need a direct replacement for OEM high-lift blades. It’s especially useful for bagging or leaf cleanup where lift matters most. If you mow primarily on flat, short grass and don’t bag, a standard-lift blade may be quieter and more efficient.
