Lawn Mower Blade ( Mulch ) for X300 and Z300 Series with 42" Deck

John Deere

John Deere mower blades are designed to exact specifications to achieve the best performance and cut quality. We use high quality steel that stays sharper longer. A flat mounting surface reduces blade stress for long life and excellent cut quality. The properly sized center hole provides for less vibration and increased machine life. When you use these mulching blades with a mulch kit, you get perfectly sized clippings that return nutrients to the yard and reduces the need to dispose of yard waste. Use John Deere mower blades for the best life and performance.
