AB2100D 21" Extended Run Time Blade Set with Bolts, Nuts and Washer Hardware for EGO LM2130, LM2133,LM2135, LM2130SP, LM2135SP, LM2150SP & LM2156SP 21" Lawn Mowers

What It Is

This is a 21-inch extended run time blade set for EGO 21” mowers, designed to improve mulching efficiency and battery runtime. It includes three blades with bolts, nuts, and washers for a complete replacement.

Fitment & Compatibility

• Deck size: 21 inches only. Measure your deck to confirm.
• Models: Fits EGO LM2130, LM2133, LM2135, LM2130SP, LM2135SP, LM2150SP, and LM2156SP. Check your mower’s model number on the sticker under the battery compartment or near the rear wheels.
• OEM vs aftermarket: This is an EGO-branded part, not a third-party knockoff. It matches stock blade hole patterns and hardware.
• Measurements: Blade length is 21”, center hole diameter is 1” (for the bolt), and the bolt size is 5/16” x 1-1/4” (included). Verify your old blade’s thickness (typically 0.125”) matches.

Key Things to Know

• Installation difficulty: Easy. Remove battery, tip mower on its side (air filter up), unbolt old blades, swap in new set. Torque bolts to 35-40 ft-lbs. No special tools needed.
• Runtime vs cutting: Extended run time means more efficient blade lift for mulching, but it may reduce bagging performance compared to standard blades. Best for mulching leaves or grass.
• Hardware included: Bolts, nuts, and washers are pre-loaded—use them. Don’t reuse old hardware; it can strip or loosen over time.
• Common gotcha: These blades are thinner than some aftermarket options. If you hit rocks often, expect faster dulling. Keep a spare set.

Should You Buy It

If you own a compatible EGO 21” mower and primarily mulch or want longer battery life per charge, this set is a solid upgrade. It’s priced fairly for OEM quality, and the included hardware saves a trip to the hardware store. Skip it if you bag frequently or need extreme durability for rough terrain.
