8TEN LawnRAZOR Blade for Gravely Exmark Pro 1536H Turf Tracer Hydro 36-Inch 00273100 116-5176-S (Toothed) 2 Pack

What It Is

The 8TEN LawnRAZOR toothed blade is a direct-replacement cutting blade for 36-inch walk-behind mowers, specifically designed for Gravely and Exmark commercial turf units. The toothed edge helps shred grass clippings finer for better mulching or bagging performance.

Fitment & Compatibility

Before buying, confirm your mower has a 36-inch cutting deck with three blades (this 2-pack covers two spindles). This blade replaces OEM numbers 00273100 and 116-5176-S. It fits the Gravely Pro 1536H and Exmark Turf Tracer Hydro 36-inch models. Measure your current blade length (should be roughly 18 inches) and center hole diameter (usually 5/8-inch). Check spindle bolt size and torque specs in your owner’s manual—some Exmark decks use a 5/16-inch bolt, but this blade uses a standard 5/8-inch center hole. Not compatible with 32-inch, 48-inch, or other deck sizes.

Key Things to Buy

• Quality: Made from heat-treated carbon steel; toothed edge stays sharp longer than standard blades but dulls faster in sandy or rocky soil.
• Installation: Straightforward bolt-on swap. Use a torque wrench (typically 70-90 ft-lbs for spindle bolts). Ensure blades are installed with the toothed edge facing the direction of rotation.
• Gotchas: The toothed design can throw debris more aggressively—wear eye protection. Check blade balance after installation; unbalanced blades cause vibration and bearing wear.
• Pairing: For best cut quality, replace all three blades at once, even if only two are in this pack. Mixing toothed with standard blades can cause uneven cutting.

Should You Buy It

Buy this if you own a Gravely Pro 1536H or Exmark Turf Tracer Hydro 36-inch mower and want better mulching or bagging performance. It’s a solid upgrade over standard blades for commercial or residential use, but skip it if your turf is sandy or rocky—the toothed edge will wear quickly. At $31.95 for a 2-pack, it’s a good value for a brand-name replacement.
