115-5059-03 110-6837-03 High Lift Blades Fit for 50 inch Toro TimeCutter MX SS SW/SWX Z 5000 5020 5500 5060 Series Mower Decks Replaces 112-9759-03, 3 Pack

What It Is

This is a set of three high-lift lawn mower blades designed to improve grass clipping discharge and bagging performance on 50-inch Toro TimeCutter and Z-series zero-turn mowers. They replace OEM part 112-9759-03 and are intended for heavy-duty mowing in thick or wet grass.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 50 inches—these blades won’t fit 42- or 60-inch decks. Compatible models include Toro TimeCutter MX, SS, SW, SWX, Z 5000, 5020, 5500, and 5060 series. Measure your existing blade length (should be about 20.5 inches) and check the center hole diameter (typically 1 inch) and spindle shape. These are aftermarket replacements for OEM part 112-9759-03, so verify your current blade’s part number matches that or is listed as a cross-reference. If your mower uses a different spindle design or offset, these won’t fit.

Key Things to Know

• Quality: Rated 4.6/5 from 311 reviews—users report sharp out of the box and durable steel that holds an edge longer than standard blades.
• Installation Difficulty: Moderate; requires jacking up the mower, removing the old blade with a socket wrench, and torquing to spec (typically 70-90 ft-lbs). Always disconnect the spark plug first.
• Common Gotchas: High-lift blades increase airflow but also create more drag, which may slightly reduce engine RPM or fuel efficiency on smaller engines. Also, they’re louder than standard blades—wear hearing protection.
• Check Deck Clearance: Ensure your deck has enough clearance for the higher lift profile; some low-clearance decks may require a different blade type.

Should You Buy It

Buy these if you need better bagging or side-discharge performance on a 50-inch Toro TimeCutter or Z-series mower, especially in lush or damp grass. They’re a solid upgrade over standard blades for users who prioritize cutting quality over noise or minor power draw. Avoid if your deck is underpowered or you primarily mulch—these aren’t optimized for mulching.
