Rotary 50" 10094 Aftermarket Replacement Lawn Mower Blade Set - 3 Blades

What It Is

This is a set of three 50-inch replacement blades for zero-turn and riding lawn mowers with a 50-inch cutting deck. Designed for medium-to-large residential or commercial properties, it replaces worn or damaged OEM blades to restore cutting performance.

Fitment & Compatibility

• Deck size: Only fits 50-inch decks. Measure your existing blade length from center hole to tip—must be exactly 50 inches when installed as a set of three.
• Brand/model fit: Primarily for Rotary brand mowers (e.g., Rotary 50" zero-turn models). Also fits many aftermarket decks with a 50-inch three-blade pattern, but always cross-check your model number with Rotary’s OEM part list.
• OEM vs aftermarket: This is an aftermarket replacement. It is not made by Rotary; verify that your deck accepts aftermarket blades (some OEM-only decks may require exact blade geometry).
• Measurements to check: Center hole diameter (usually 5/8" or 7/8"), blade thickness (typically 0.1875" or 0.25"), and blade offset (flat or angled). Confirm these match your current blades.

Key Things to Know

• Quality: High carbon steel with a heat-treated edge; holds sharpness well for residential use, but may dull faster than premium OEM blades on rocky or sandy soil.
• Installation: Straightforward—remove old blades, install new ones with the correct orientation (cutting edge facing forward). Use a torque wrench; tighten center bolts to 70–90 ft-lbs.
• Common gotchas: Three-blade sets must be balanced together. If one blade is slightly heavier, you’ll get vibration and uneven cut. Weigh each blade before installing.
• Warranty: Aftermarket, so no OEM warranty. Check return policy for fitment issues—some sellers offer 30-day fitment guarantees.

Should You Buy It

If you have a 50-inch Rotary or compatible mower and want a budget-friendly replacement that delivers solid cutting performance for regular lawn maintenance, this set is a reliable choice. Skip it if you need exact OEM geometry for commercial use or if your deck requires specific blade shape/offset not listed.
