8TEN LawnRAZOR Blade for Exmark Lazer Z E-Series Turf Tracer 52 Inch Deck 103-6397 116-5175 (Toothed) 3 Pack

What It Is

The 8TEN LawnRAZOR Blade is a toothed (serrated) replacement blade for Exmark Lazer Z E-Series and Turf Tracer mowers with a 52-inch deck. Designed for heavy-duty cutting of thick, wet, or overgrown grass, the serrated edge helps reduce clumping and improves mulching performance.

Fitment & Compatibility

• Deck size: Fits 52-inch Exmark decks only. Measure your deck width to confirm.
• Model fit: Compatible with Exmark Lazer Z E-Series and Turf Tracer models. Not for other Exmark series (e.g., Lazer Z X-Series) without verifying blade pattern.
• OEM cross-reference: Replaces OEM part numbers 103-6397 and 116-5175. These are the standard 18.5-inch blades for those decks.
• Measurements: Blade length is 18.5 inches, center hole diameter is 1 inch, and thickness is 0.203 inches. Check your spindle and blade bolt size (typically 5/8-inch) to ensure a match.
• Aftermarket note: LawnRAZOR is a third-party brand; fitment is generally reliable but always compare the blade’s shape and mounting hole pattern to your old blade before installing.

Key Things to Know

• Toothed edge: The serrated design cuts better in wet or tall grass but may leave a slightly rougher finish on fine lawns compared to standard blades.
• Installation: Straightforward—remove the old blade, clean the spindle, and torque the bolt to 70-90 ft-lbs. Use a blade removal tool or block of wood to prevent spinning.
• Durability: Made from heat-treated steel; holds an edge well but can dull faster if you hit rocks or roots frequently. Check for bends or nicks after each season.
• 3-pack value: At $42.95, it’s cheaper than OEM blades per blade. Replace all three at once for even wear and balance.

Should You Buy It

Buy this if you own a 52-inch Exmark Lazer Z E-Series or Turf Tracer and need a cost-effective, heavy-duty blade for tough cutting conditions. It’s a solid aftermarket choice for property owners who prioritize cutting power over a perfect manicured finish. Skip it if you demand a pristine, golf-course-quality cut or if your deck requires non-serrated blades.
