What It Is

This is a set of three aftermarket 50-inch mower blades designed for zero-turn mowers, specifically the Toro TimeCutter SS5000, MX5000, MX5050, MX5060, and Exmark Quest models. They replace OEM blades 110-6837-03 and 112-9759-03, intended for cutting grass on residential and light commercial turf.

Fitment & Compatibility

Before buying, verify your mower deck is 50 inches and uses three blades. This set fits:

• Toro TimeCutter: SS5000 (model 75750), MX5000 (model 75755), MX5050, MX5060.
• Exmark Quest: models requiring blade 142-6453-S.
• OEM cross-references: 110-6837-03, 112-9759-03, and 115-5059-03.

Check these specifics:

• Blade length: 16.5 inches (center hole to tip).
• Center hole diameter: 5/8 inch (common for these decks).
• Sail height and shape: match your old blade’s profile (airlift vs. low-lift). These are typically medium-lift for bagging or side discharge.
• Confirm your deck’s spindle pattern (three-blade 50-inch) – not compatible with 42-inch or 54-inch decks.

Key Things to Know

• Quality: BlueStars blades are heat-treated steel (usually 10-gauge). They’re comparable to OEM for residential use but may not hold an edge as long under heavy commercial use.
• Installation: Straightforward – use a socket wrench (5/8-inch or 3/4-inch for bolt) and torque to 70-90 ft-lbs. Always lift the deck or remove the battery before working.
• Balance: Out of the box, these blades are typically balanced, but it’s worth checking with a blade balancer to avoid vibration.
• Common gotcha: The included bolts/nuts may not match your spindle’s thread pitch (usually 5/8-18). Reuse your OEM hardware if needed.

Should You Buy It

If you own a Toro TimeCutter or Exmark Quest 50-inch deck and need a budget-friendly replacement for residential mowing, this three-pack is a solid value at $35.99. It’s not ideal for heavy commercial use or if you demand OEM-grade durability, but for homeowners doing weekly cuts, it delivers good lift and clean cuts. Verify your deck size and blade length before ordering.
