Oregon 96-660 G3 Gator Blade

What It Is

The Oregon 96-660 G3 Gator Blade is an aftermarket mulching blade designed for EGO cordless lawn mowers. It uses a patented “Gator” tooth pattern to chop clippings finer than a standard blade, improving mulch quality and reducing bagging frequency.

Fitment & Compatibility

• Deck size: Fits EGO mowers with a 21-inch cutting deck (e.g., LM2100, LM2102SP, LM2135SP, LM2142SP).
• OEM vs aftermarket: Direct replacement for EGO part number 2825961001.
• Measurements: 21” length, 0.175” thickness, 0.75” center hole, 0.50” offset.
• Check: Remove your old blade and measure the center hole diameter and offset direction. If your mower uses a 0.75” hole with a 0.50” offset, this fits. Does not fit 20” or 22” decks.

Key Things to Know

• Cut quality: The G3 tooth design produces significantly finer clippings than a standard blade, reducing clumping and leaving a cleaner lawn.
• Installation: Easy swap—use a 15/16” socket or wrench. No special tools needed. Torque the bolt to 30-35 ft-lbs.
• Gotchas:
  • Not for bagging-only use; works best with the mulching plug installed.
  • Slightly heavier than OEM—may reduce runtime by 5-10% on a full charge.
  • Do not sharpen the G3 teeth; only sharpen the main cutting edge if needed.
• Durability: Heat-treated steel holds an edge well, but hitting rocks or roots can chip the teeth.

Should You Buy It

Yes, if you own a 21-inch EGO mower and want noticeably better mulching performance. It’s a simple upgrade that reduces bagging trips and leaves a finer finish. Skip it if you primarily bag clippings or run on very low battery—the extra weight cuts runtime slightly.
