How do the dimensions affect fit and cutting performance?

The blades' exact measurements ensure bolt-hole alignment and proper blade-to-deck clearance, which are critical for mulching and balanced rotation. Using the correct length, width, thickness, and center hole prevents vibration and maintains the mower’s intended airflow for clippings.

• Length: 19 3/8" ensures full deck coverage and correct tip speed.
• Width: 2 1/4" preserves cutting path and mulching chamber shape.
• Thickness: 0.157" for strength and reduced bending under load.
• Center hole: 5/8" for secure mounting to factory spindles or adapters.

What are practical installation and maintenance tips?

Install the blades in matched pairs and torque the mounting hardware to factory specifications. Keep blades sharp and replace when bent, cracked, or worn beyond safe cutting geometry to retain fuel efficiency and cutting quality.

• Replace blades two at a time for balanced operation.
• Check blade torque after first hour of use and periodically afterward.
• Sharpen lightly for consistent cutting; discard if the edge is excessively notched or the blade is warped.

Why choose this 2-pack from 8TEN instead of a single OEM blade?

Buying the 8TEN two-pack saves time and ensures both sides of the deck receive matched blades for even performance. These blades are manufactured to match OEM specs so fitment and mulching action remain consistent with the mower’s original design.

• Two blades sold together for balanced replacement and fewer purchases.
• Manufactured to OEM dimensions to reduce fitment issues and vibration.
• Cost-effective alternative to buying single OEM blades while maintaining compatibility.
