Cordless Weed Wacker for Milwaukee M18 Battery, 3 IN 1 Battery Powered Weed Eater & Edger & Mower w/Auto Line Feed, 20000 RPM 12 Inch Electric Grass Trimmer,6 Blades & 4 Spools String Trimmer for Lawn

What It Is

This is a 3-in-1 cordless weed wacker, edger, and mini mower that runs on Milwaukee M18 batteries. It’s designed for trimming grass, edging along sidewalks/driveways, and light mowing in tight spaces, not for full lawn mowing.

Fitment & Compatibility

• Battery: Requires any Milwaukee M18 battery (sold separately). Works with XC or HD batteries; compact 2.0Ah batteries will run about 15–20 minutes, while 5.0Ah or larger gives 30–40 minutes.
• Deck/mower fit: This is a standalone tool, not a blade for an existing mower. No deck size or model compatibility to check.
• Accessories: Comes with 6 blades (likely plastic/universal) and 4 spools of line (0.080” or 0.095” typical). Replacement line should match spool diameter—check your spool markings before buying refills.
• Mounting: Not designed to attach to a tractor or walk-behind mower. It’s a hand-held unit with a wheeled mower attachment for ground contact.

Key Things to Know

• Auto line feed: The head advances line automatically when you tap it on the ground or rev the motor. No manual bumping required, but keep the spool wound neatly to avoid jams.
• Blades vs. string: The 6 included blades are for thicker brush or light weeds. Swap to string for standard grass trimming. Blades wear fast on rocks or concrete.
• Installation/difficulty: No assembly needed out of the box—just attach battery and adjust handle. Changing line or blades takes under 2 minutes with no tools.
• Gotcha: The “mower” function is a small wheeled attachment for level trimming, not a replacement for a push mower. Best for edging or final cleanup, not cutting a whole lawn.

Should You Buy It

Buy this if you already own Milwaukee M18 batteries and need a versatile, lightweight trimmer/edger for small yards, edging, or tight spots. Skip it if you need a full-size mower or prefer gas power for heavy brush. The 4.9-star rating and included accessories make it a strong value for Milwaukee ecosystem users.
