Oregon 91-626 PK6 Mower Blades - 21" (1 Pack)

What It Is

The Oregon 91-626 PK6 is a pack of 6 aftermarket 21-inch mulching blades designed for EGO cordless lawn mowers. These blades replace OEM EGO blades and are intended for mulching grass clippings into fine particles that decompose quickly.

Fitment & Compatibility

• Deck size: Fits mowers with a 21-inch cutting deck only. Measure your deck width to confirm.
• Model check: Compatible with EGO LM2100, LM2101, LM2102SP, LM2110SP, LM2130SP, LM2135SP, and LM2142SP models. Verify your mower’s model number on the chassis or manual.
• OEM vs aftermarket: Oregon is a reputable aftermarket brand. These blades are direct replacements for EGO part numbers 2822881001, 2822881002, and 2822881003.
• Measurements: Blade length is 21 inches, center hole is 1 inch, and the drive pin hole is 0.25 inches. Ensure your mower’s blade adapter matches these specs.

Key Things to Know

• Quality: Made from heat-treated steel with a durable coating. Sharper than OEM blades out of the box, but may dull slightly faster in sandy or rocky soil.
• Installation: Easy with a socket wrench. Use a blade removal tool to lock the spindle. Torque bolts to 30-35 ft-lbs. No special adapters needed.
• Common gotcha: These are mulching blades, not lift or bagging blades. They won’t throw grass into a bagger as effectively. Use only for mulching or side discharge.
• Pack size: You get 6 blades, which is a 2-3 season supply for a typical lawn. Replace all blades at once for balanced cutting.

Should You Buy It

Buy this if you own a compatible 21-inch EGO mower, want a cost-effective mulching blade upgrade over OEM, and prefer to stock up for multiple seasons. Skip it if you need bagging-specific blades or have a smaller/larger deck size.
