🛠️ John Deere Pro-Tip: The 42" deck is the most popular JD setup, but it relies on sharp blades to maintain its "High-Lift" vacuum. Maintenance Tip: When installing, ensure the "lift" side of the blade faces UP toward the deck. If your 7-point star on the spindle is rounded off, replace the spindle before installing new blades to ensure a safe, locked fit.
This part is 100% Brand New. Each blade is factory-balanced and sharpened with a durable protective finish to prevent rust while in storage or on your mower.
