Exmark 116-5176-S Extreme Blade Set Turf Tracer Viking Hydro Metro 36 Inch 2 Pack

What It Is

The Exmark 116-5176-S Extreme Blade Set is a pair of OEM replacement blades designed for 36-inch Exmark walk-behind mowers, including Turf Tracer, Viking Hydro, and Metro models. These blades are built for high-performance cutting and mulching on commercial or residential turf.

Fitment & Compatibility

Before buying, verify your mower deck size is exactly 36 inches—this set will not fit smaller or larger decks. Confirm your Exmark model is one of the following: Turf Tracer (all series), Viking Hydro, or Metro. The blade length is 18.5 inches, with a 1-inch center hole and a 5-point star drive pattern. Check that your spindle assembly matches this star pattern; older or non-Exmark spindles may require a different adapter. These are genuine OEM parts, so aftermarket “universal” blades with different hole shapes will not work.

Key Things to Know

• Quality: Made from heat-treated steel for durability; the “Extreme” design includes a thicker cross-section and a sharper cutting edge for cleaner cuts and longer life than standard blades.
• Installation: Moderate difficulty—requires a socket wrench and torque wrench (recommended torque: 70-90 ft-lbs). Always lift the deck and block it safely; never rely on the mower’s lift handle alone.
• Common gotchas: The star drive pattern can be finicky—ensure the blade aligns fully on the spindle before tightening. Also, these blades are not for bagging or side-discharge use; they are optimized for mulching.
• Wear check: Replace when cutting edges are dull or nicked, or if the blade is bent (spin test on the spindle to check balance).

Should You Buy It

If you own a 36-inch Exmark Turf Tracer, Viking Hydro, or Metro and need a direct OEM replacement that maintains factory cutting performance, this set is a solid choice. The $58 price is competitive for genuine Exmark parts, and the 4.2-star rating reflects reliable quality. Avoid if you need blades for bagging or side-discharge, or if your mower uses a different spindle pattern.
