• Curved mulching edge encourages recirculation and finer clipping size
• Balanced design minimizes vibration for a smoother cut

• Blade length: 17 inches; width: 2.75 inches
• Thickness: approximately 0.157 inches for strength and wear resistance
• Center mounting: 7-point star hole to match many John Deere spindles

How do I install and care for this replacement blade?

Installation is straightforward for anyone comfortable working with mower decks: disconnect the spark plug, raise the deck, and swap blades using the correct torque for your spindle nuts. Routine care extends blade life and maintains cutting quality.

• Always disconnect power before changing blades; use manufacturer torque specs
• Sharpen periodically and inspect for bends or chips after heavy use
• Balance blades after sharpening to prevent vibration and spindle wear
