This aftermarket replacement blade, identified by part number 6484NO, is specifically designed for AYP (American Yard Products) lawn mowers featuring a 107 CM (42-inch) cutting deck with a rear ejection system. As a right-hand side blade, it is crucial for multi-blade setups, ensuring proper cutting overlap and efficient grass discharge towards the rear of the mower. Crafted as a high-quality, non-OEM alternative, this blade offers reliable performance comparable to original specifications. It is engineered to provide a clean, precise cut, contributing to a well-maintained lawn. The design is optimized for rear-eject decks, facilitating the effective channeling of grass clippings to the rear collection bag or deflector, preventing clumping and improving overall cutting efficiency. This compatible blade is suitable for a wide range of lawn tractors and riding mowers manufactured by AYP, which often includes models from brands such as Husqvarna, Poulan, and Craftsman that utilize a 42-inch rear discharge deck. Before purchase, it is recommended to verify the dimensions and center hole configuration (typically a 5-point or 6-point star) against your existing blade to ensure perfect fitment and optimal operation. Choosing this aftermarket blade provides a cost-effective solution for maintaining your mower's cutting performance.
