Built for lawn owners who need consistent mulching performance on 48-inch decks, the KANXAJJY blades are engineered to match the mounting pattern and cutting profile of the OEM John Deere parts. Each blade measures 17 inches long, 2-1/2 inches wide and 0.197 inches thick, with a 4/5" center hole, making them an economical way to restore lift, clipping circulation, and shred performance on a wide range of John Deere tractors and ZTrak mowers.

How do these high-lift blades affect cutting and mulching?

High-lift blades create stronger upward airflow beneath the deck, keeping grass clippings suspended longer so they get cut repeatedly and expelled as finer mulch. That improves redistribution and reduces visible clumps, supporting a healthier-looking lawn when used with the right deck and mowing technique.

• High-lift profile increases suction for better clipping circulation.
• Taller airflow helps finely chop clippings for mulching return to turf.
• Designed edges promote consistent discharge and reduced clogging.

What John Deere models are compatible with these blades?

This 3-pack is listed for a broad range of John Deere lawn tractors, select series, multi-terrain tractors, and ZTrak/ZTrak EZtrak mowers that accept the specified replacement numbers. Always cross-reference the part number or your mower’s parts diagram before installing.

• Works on tractors and zero-turn models using the 48" deck with the same mounting hole pattern.

How should I install and maintain these replacement blades?

Installation follows standard mower blade replacement steps: disconnect spark, raise the deck, secure the blade, and torque the spindle bolt to the manufacturer’s specification. Regular inspection, sharpening, and balancing keep cut quality high and extend blade life.

• Always disconnect the spark plug and stabilize the tractor before service.
• Tighten to your mower’s specified bolt torque; use a new washer/bolt if recommended.
• Sharpen and balance blades periodically; replace if bent, cracked, or excessively worn.
