MowerPartsGroup (6) Medium-Lift Blades fits Toro TimeCutter Z 50" Deck Replaces 110-6837-03

What It Is

This is a set of three medium-lift replacement blades designed for 50-inch cutting decks, specifically for Toro TimeCutter zero-turn mowers. The medium-lift profile balances grass clipping discharge with mulching performance, making it suitable for regular residential mowing on flat to moderately uneven lawns.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch Toro TimeCutter deck (model numbers typically start with 746xx or 747xx). The OEM part number these replace is 110-6837-03. Measure your existing blade length—these should be 16.5 inches from tip to tip, with a center hole diameter of 5/8 inch and a 0.25-inch thickness. Do not assume fitment for other Toro models (e.g., Titan or Z-Master) or non-Toro brands without verifying deck size and blade dimensions. Check your current blade’s part number stamped on the blade itself to confirm.

Key Things to Know

• Quality: These are aftermarket blades made from hardened steel with heat-treated edges. They are a direct replacement for OEM Toro blades but may have slightly different finish or coating (usually black powder coat vs. OEM’s bare steel).
• Installation difficulty: Easy—requires a socket wrench and a blade removal tool or block of wood to prevent spinning. Torque to 70–90 ft-lbs per Toro specs.
• Common gotchas: The medium lift can reduce bagging efficiency on wet or tall grass. For heavy mulching, consider a high-lift blade. Always replace all three blades as a set to maintain deck balance.
• Sharpening: Can be sharpened 2–3 times before replacement. Balance after sharpening using a blade balancer.

Should You Buy It

If you own a Toro TimeCutter with a 50-inch deck and want reliable, cost-effective blades that perform similarly to OEM without the price premium, these are a solid choice. They work best for routine mowing on dry grass where you want good discharge without excessive dust or power draw. Avoid if you need dedicated mulching or bagging blades.
