MowerPartsGroup (3) Replacement Toro Blades 110-6837-03 112-9759-03

What It Is

This is a set of three replacement blades for select Toro lawn mowers, designed to deliver a clean cut on standard residential lawns. They fit TimeCutter, Titan, and Z-Master zero-turn models with 50-inch or 54-inch decks.

Fitment & Compatibility

Before buying, confirm your mower’s deck size and blade part numbers. These blades replace Toro OEM part numbers 110-6837-03 and 112-9759-03. They fit Toro TimeCutter 50-inch decks (e.g., SS5000, 74750), Titan 54-inch decks (e.g., 75402), and Z-Master 54-inch decks (e.g., 74500). Measure your existing blade length (should be ~20.5 inches) and center hole diameter (usually 1 inch or 7/16 inch). These are aftermarket blades, not OEM Toro, so check that the mounting holes align with your spindle assembly. Verify your mower’s model number on the deck or owner’s manual to avoid returns.

Key Things to Know

• Quality: Made from heat-treated steel with a hardened edge, similar to OEM, but may not last as long in heavy or rocky conditions.
• Installation: Straightforward—remove the old blade, clean the spindle, and torque the bolt to 70-90 ft-lbs. Use a blade removal tool for safety.
• Common gotcha: Blades may be slightly thicker than OEM, causing minor vibration if not balanced. Check balance with a blade balancer before install.
• Packaging: Comes as a set of three, so you can replace all at once for even cutting.

Should You Buy It

If you need a budget-friendly replacement for your Toro zero-turn and don’t mind aftermarket quality, this set is a solid choice. It’s ideal for routine maintenance on residential lawns, but skip it if you mow heavy commercial turf or demand OEM-grade durability.
