JXJKCZ 52" Deck Mower Blades 3-Pack — Notched High-Lift Replacement for Exmark and Toro, Hardened Steel

These are three notched high-lift 52-inch replacement mower blades engineered to fit Exmark and Toro decks that use OEM 103-6402-S / 109-6873-style blades.

If your zero-turn or commercial mower with a 52" deck needs fresh, high-lift cutting edges, this 3-pack from JXJKCZ restores lift, discharge, and cut quality for many Exmark Lazer, Turf Tracer, Pioneer, Vantage and Toro models. The blades are formed and heat-treated to match the performance profile of the OEM part numbers, and the notched design helps maintain airflow and bagging ability on decks that specify this shape.

Which mower models and OEM numbers do these blades replace?

These blades are manufactured to be compatible with common OEM references for 52-inch decks. They are designed to match fit and function where the listed Exmark and Toro part numbers are specified.

• Replaces Exmark OEMs: 103-6402, 103-6402-SU, 103-6402-S
• Replaces Toro OEM: 109-6873
• Fits Exmark series: Lazer Z (E, X, AS, CT, HP, AC), Lazer S, Turf Tracer, Pioneer, Vantage, Radius and Staris/Quest variants

How do these notched high-lift blades affect cutting performance?

Notched high-lift blades produce stronger upward airflow beneath the deck, which improves lift of grass for an even cut and more effective discharge or bagging. The notches help clear stringy clippings and reduce clogging on heavy or wet turf when paired with a properly adjusted deck.

• High-lift profile increases suction for cleaner strand stand-up
• Notches aid in chip and clumping clearance
• Helps improve side-discharge and bagging efficiency on compatible decks

What material and quality controls are used on these replacement blades?

JXJKCZ blades are made from hardened steel and heat-treated to retain edge strength and resist deformation under normal use. Quality processes focus on dimensional accuracy to ensure bolt-hole alignment, length, and cutting edge geometry match OEM standards for safe installation and reliable operation.

• Precision stamping for consistent hole placement and length
• Heat treatment for edge durability and wear resistance
• Balanced finish to reduce vibration when installed

How should I install and maintain these blades for best results?

Installation follows the mower manufacturer’s torque and safety recommendations: lift the deck, secure blades with correct bolts, and torque to spec. Regular sharpening, inspecting for bends or cracks, and replacing in matched sets when wear is significant will keep the deck cutting evenly and extend deck component life.

• Replace blades in matched sets of three for 52" decks
• Check and tighten blade bolts after initial run-in hours
• Sharpen periodically and replace if cracked, bent, or excessively worn
