Oregon 592-615 Pack of 2 Gator G5 Blades - 21-3/8"

What It Is

The Oregon 592-615 Gator G5 blade pack contains two 21-3/8-inch mulching blades designed for select EGO battery-powered walk-behind mowers. These aftermarket blades use a serrated edge to chop clippings finer than standard blades, reducing bagging frequency and improving lawn appearance.

Fitment & Compatibility

Check these before buying:

• Deck size: Fits mowers with 21-inch cutting decks (actual blade length is 21-3/8").
• EGO models confirmed compatible: LM2100, LM2101, LM2102, LM2102SP, LM2142SP, LM2150, LM2156SP. Not compatible with older EGO models (e.g., LM2000, LM2010) or most other brands.
• OEM vs aftermarket: OEM EGO blade part is 592-615 (same Oregon number). This is a direct replacement, not a universal fit.
• Measurement: Center hole is 1-inch round with a 5-point star drive. Blade thickness is 0.125 inches. Measure your old blade’s length and hole pattern before ordering.

Key Things to Know

• Quality: Oregon is a reputable aftermarket brand. G5 blades are heat-treated and coated for durability, but some users report they dull faster than OEM EGO blades on thick, wet grass.
• Installation: Easy swap with a socket wrench. Use a blade removal tool or block the blade to prevent spinning. Torque bolts to 35-45 ft-lbs. The star drive pattern can strip if over-torqued.
• Common gotcha: These blades are slightly heavier than OEM, which can cause more vibration on some mowers. Balance them before installing—use a blade balancer or mark the heavy side and file it down.
• Performance: Best for mulching. Not ideal for bagging—the fine mulch clogs bags quickly. For side discharge, they work fine but leave a finer strip of clippings.

Should You Buy It

Buy these if you own a compatible EGO 21-inch mower and want better mulching performance than OEM blades—especially if you mow often and want to skip bagging. Skip them if you prefer bagging, have an older EGO model, or want the longest possible blade life (OEM blades last longer on abrasive lawns).
