What It Is

This is a set of three high-lift lawn mower blades designed for Toro Timecutter Z5000 zero-turn mowers with a 50-inch cutting deck. High-lift blades create stronger upward airflow to improve grass clipping discharge and bagging performance, making them ideal for thick or tall grass.

Fitment & Compatibility

Before buying, verify your mower model and deck size. These blades fit Toro Timecutter Z5000 models 74370, 74372, 74373, 74374, 74375, and 74376—all with a 50-inch deck. They replace OEM part numbers 110-6837-03, 112-9759-03, and 115-5059-03. Measure your existing blade length (should be roughly 18 inches), center hole diameter (typically 1 inch), and spindle shape to confirm match. This is an aftermarket set, not genuine Toro, but designed to meet OEM specs.

Key Things to Know

• Quality: Made from heat-treated steel for durability, but some users report slightly thinner metal than OEM Toro blades—fine for residential use, less ideal for heavy commercial mowing.
• Installation: Straightforward bolt-on replacement; use a torque wrench to tighten spindle bolts to 70-90 ft-lbs. No special tools needed, but lift or block the deck safely.
• Common Gotchas: High-lift blades increase engine load and may reduce fuel efficiency slightly. They also throw clippings farther—watch for debris near bystanders. Not recommended for mulching; use standard blades for that.
• Balance: Check blade balance after installation; some sets may need light balancing to prevent vibration.

Should You Buy It

If you own a Toro Timecutter Z5000 with a 50-inch deck and want better bagging or discharge performance for thick grass, this aftermarket set is a solid, budget-friendly choice. Avoid if you primarily mulch or need OEM-grade durability for daily commercial use.
