What It Is

This is a set of replacement mower blades designed for 50-inch cutting decks on Toro TimeCutter, SS5000, MX5060, and 75755 zero-turn mowers. They handle grass up to moderate thickness and are suitable for residential and light commercial use.

Fitment & Compatibility

Before buying, verify your deck is exactly 50 inches (not 42 or 54). These blades cross-reference with OEM part numbers 115-5059-03, 79016P, 110-6837-03, and 112-9759-03. They fit Toro TimeCutter 50-inch models (all series), SS5000, MX5060, and the 75755 zero-turn. Measure your existing blade length (should be ~20.5 inches). Also check the center hole diameter (typically 1 inch) and the drive pin pattern. Aftermarket versions may vary slightly in thickness or material—confirm they match your spindle’s mounting holes.

Key Things to Know

• Quality: These are OEM Toro blades (or high-grade aftermarket equivalents). They’re heat-treated for durability but not designed for heavy mulching or wet grass.
• Installation: Straightforward if you have a socket set and jack stands. Lift the deck safely, remove the old blades with a breaker bar (left-hand thread on some spindles), and torque new ones to 70-90 ft-lbs.
• Gotchas: Always check blade direction—the sharp edge faces the direction of rotation. After installation, run the deck for 30 seconds and re-torque. Don’t mix old and new blades on the same spindle.
• Common Mistake: Using these on a 42-inch or 54-inch deck will cause poor cut quality and potential spindle damage. Measure twice.

Should You Buy It

If you own a Toro 50-inch zero-turn (TimeCutter, SS5000, MX5060, or 75755) and need direct OEM-spec replacement blades for regular mowing, this is a solid choice. It’s not ideal for heavy mulching or commercial daily use—consider gator blades for that. For standard residential lawns, it’s a reliable, well-rated pick.
