Earthtec 996516001 Mower Blades Replacement for Ryobi Lawn Tractor RY48110 RY48111 RY48112 Lawnmower Replace (2 Pcs)

What It Is

This set of two replacement mower blades is designed specifically for Ryobi RY48110, RY48111, and RY48112 lawn tractors. They are used for cutting grass on residential lawns and are compatible with 42-inch cutting decks.

Fitment & Compatibility

Before buying, confirm your mower’s model number (RY48110, RY48111, or RY48112) and that your deck is 42 inches. These are aftermarket blades, not OEM Ryobi parts. Measure your existing blade length (should be 21 inches center-to-center) and check the center hole diameter (typically 1 inch) and the blade thickness (about 0.2 inches). Ensure the blade shape matches—these have a curved wing design for lift. If your deck uses a different blade pattern (e.g., 46-inch or 54-inch), these will not fit.

Key Things to Know

• Quality: Made from heat-treated steel, but some users report they dull faster than OEM blades on rocky or sandy soil.
• Installation: Straightforward if you have a socket set and a torque wrench—tighten to 70-80 ft-lbs. Use a blade stop tool or block of wood to prevent spinning.
• Common gotcha: These blades are slightly lighter than OEM, which may cause vibration if not balanced. Always check balance before installing.
• Set includes: Two blades—verify your deck uses two blades (most 42-inch Ryobi tractors do), not three or four.

Should You Buy It

If you need a budget-friendly replacement for your Ryobi 42-inch tractor and can handle basic blade swapping, these are a solid pick. They’re not as durable as OEM for heavy use or rough terrain, but for regular residential mowing, they offer good value. Avoid if you have a different deck size or prefer OEM longevity.
