How do I install and maintain this replacement blade?

Installation follows standard mower blade replacement steps: disconnect spark, remove spindle nut, transfer adapters if needed, and torque hardware to manufacturer specs. Regular maintenance includes sharpening when dull, balancing after sharpening and replacing blades that show cracks or excessive wear.

• Always remove spark plug wire before servicing the deck
• Torque mounting hardware to your mower's recommended specification
• Sharpen and balance blade to prevent vibration and uneven cuts
• Inspect for cracks, bends or worn mounting holes before reuse
