High lift for better airflow and bagging

The high-lift geometry creates stronger airflow through the blade, which can improve clippings collection and help maintain an even cut, especially when grass is tall or dense. The blades are built from sturdy metal and finished with a powder-coated coating that adds durability and a safer edge.

• Predicted performance: improved bagging and less buildup at the discharge chute
• Cutting consistency: helps you achieve an even surface across the width of a 48-inch deck

Rugged construction and practical use

These blades are designed to stand up to challenging mowing conditions, including wet grass, mud, and minor obstacles like rocks or small stumps. Note that they’re not designed for sandy or loose soil, where blade wear and performance can differ.

In real-world use, you might notice the coating gradually wears to reveal the sharp edge, which some users interpret as an indicator of readiness to cut. This is a natural part of the finish on powder-coated blades.

Installation and fitment

Swapping in takes minutes with a suitable torque wrench and the correct bolt. Ensure the two blades mount with the cutting edge facing the same direction for balanced performance. The standard blade dimensions help you verify compatibility before ordering.

• Blade length: 16-3/4 inches
• Width: 2-1/2 inches; Thickness: 0.2020 inches
• Center hole: 5-point star; Deck size: 48 inches; Lift: High Lift

The 3-pack offers convenience and value for routine maintenance, giving you ready replacements as wear marks appear. Always check your blade part number and spindle pattern before ordering to ensure a precise fit.
