How easy is installation and what maintenance is recommended?

• Quick swap—fits directly without deck modification
• Pre-sharpened and safety-coated; paint wears off during break-in
• Resharpen with standard blade sharpening tools when edges dull
• Inspect blade balance and fasteners each season for safe operation

• High-strength steel construction for stability under load
• Durable cutting edge that accepts resharpening safely
• Designed to withstand frequent contact with grass and normal debris
• Sold as a three-pack so you can replace blades on multiple spindles or keep spares
