These replacement blades match OEM numbers 116-5174-S, 103-6398 and 103-6398-S and are engineered for high-performance cutting on 60-inch decks used in professional and property-maintenance equipment.

Which mower models will these JXJKCZ blades fit?

These blades are specified for 60" cutting decks and fit a wide range of Exmark Lazer Z series mowers and Turf Tracer models. They cover Lazer Z E-, AC, AS, CT, LC, Next, XP, XS, Z-Series, S-Series and X-Series machines listed by manufacturer model codes, plus Turf Ranger and Turf Tracer Hydro and X-Series units.

• Exmark Lazer Z models: LZE27KC604, LZ23KC604, LZ27KC604 and many LZ*/LZZ*/LZX* 60" variants.
• Turf Tracer / Turf Ranger: FMD604/TR23KC and TTX/TT series models with 60" decks.
• Confirm fit by matching OEM 116-5174-S, 103-6398 or 103-6398-S and blade specs.

How do the blade dimensions affect performance and compatibility?

The exact length, center-hole diameter, width and thickness determine both cutting performance and whether the blade mounts correctly. These JXJKCZ replacements use the standard 20 1/2" length and 15/16" center hole for a secure fit, while the 2 1/2" width and .203" thickness balance rigidity and edge retention for routine commercial mowing.

• 20 1/2" length aligns with most 60" deck blade mounts and balance specs.
• 15/16" center hole ensures proper hub seating and safe rotation.
• 2 1/2" width and .203" thickness provide structural strength under heavy load.

What maintenance and installation tips should a user follow?

Always replace blades in matched sets and follow the mower manufacturer’s torque and safety instructions. Inspect blade balance, clean mounting surfaces, and use the correct hardware and torque values to avoid vibration and ensure even cut quality.

• Replace all three (or all deck) blades at once to maintain balance and even cut.
• Check and match blade orientation (leading/trailing edge) during installation.
• Torque bolts to Exmark recommended specifications and recheck after initial run.
