Rotary 36" 6294 Commercial Gator Mulch Lawnmower Blade Set (2) 5/8" Center Hole Copperhead

What It Is

The Rotary 36" 6294 Commercial Gator Mulch Lawnmower Blade Set is a pair of mulching blades designed for 36-inch commercial walk-behind mowers. The “Gator” style uses a notched, serrated edge to chop clippings finer than standard blades, ideal for leaving mulch on the turf.

Fitment & Compatibility

Before buying, confirm your mower has a 36-inch cutting deck and uses blades with a 5/8-inch center hole (this set has a 5/8" hole, not the common 7/8" or 1" found on many residential decks). Measure your existing blade’s length—this set is 36 inches total (two 18-inch blades). It’s an aftermarket replacement for OEM blades on brands like Exmark, Scag, Toro, and John Deere commercial 36-inch mowers, but not for standard 36-inch residential tractors (those often use a single long blade). Check your owner’s manual or measure your current blade’s length, center hole diameter, and thickness (these are 0.203" thick). If your OEM blades have a different hole size or are significantly thicker, this set won’t fit.

Key Things to Know

• Quality: Made from hardened steel with a copperhead coating to resist rust and wear. The serrated mulch edge is aggressive—good for thick grass but may leave a slightly rougher cut than a standard lift blade.
• Installation: Easy if you have a torque wrench. Tighten blade bolts to 70–90 ft-lbs (check your mower’s spec). The 5/8" hole fits most commercial spindles, but ensure your blade bolt washer is in good shape to prevent slipping.
• Gotchas: These are mulching blades, not for bagging or side-discharge. They work best with a mulch kit installed. If you switch between mulching and bagging, you’ll need to swap blades. Also, the set comes as two blades—some 36" decks use three blades; verify your deck layout.
• Balance: Each blade is individually balanced, but always recheck balance after sharpening or if vibration occurs.

Should You Buy It

Buy this set if you run a 36-inch commercial walk-behind with a 5/8" center hole and want aggressive mulching performance without paying OEM prices. It’s a solid value for high-use mowing on turf you want to leave finely chopped, but skip it if you need standard lift blades for bagging or if your deck uses a different hole size.
