Greenworks 48V (24V x 2) 21" Brushless Self-Propelled Mower+12" String Trimmer+320CFM Blower,(2) 5.0Ah Batteries and 4A Dual Port Charger

What It Is

This is a complete 48V (24V x 2) cordless outdoor power equipment system from Greenworks, including a 21" self-propelled mower, 12" string trimmer, and 320 CFM blower, powered by two 5.0Ah batteries and a dual-port 4A charger. It’s designed for homeowners with medium-sized lawns (up to 1/3 acre) who want a single-brand, battery-powered solution for mowing, trimming, and blowing.

Fitment & Compatibility

• Mower Deck Size: 21" steel deck – fits standard residential lawns but won’t work with zero-turn or ride-on mowers.
• Battery System: Uses Greenworks 24V G-Max batteries (sold separately in 2Ah, 4Ah, 5Ah, and 6Ah). Batteries and charger are not cross-compatible with Greenworks 40V or 80V systems.
• OEM vs Aftermarket: Batteries and charger are OEM Greenworks. Aftermarket 24V batteries may physically fit but can cause reduced performance, shorter lifespan, or charger error codes.
• Model Check: Verify your mower model number (e.g., 2100702, 2109702) to ensure the batteries/charger match. The dual-port charger (model 29972) works with all Greenworks 24V G-Max batteries.
• Physical Check: Measure your storage space – the mower folds but is bulky (approx. 60"L x 22"W x 38"H when assembled). Trimmer and blower are compact.

Key Things to Know

• Quality: Solid build for the price. Mower brushless motor is quiet and efficient. Trimmer uses a bump-feed head (replaceable .080" line). Blower is decent for leaves but not heavy wet debris.
• Installation Difficulty: Minimal – mower requires handle assembly (tools included), trimmer and blower are ready out of box. No special tools needed.
• Common Gotchas:
  • The 5.0Ah batteries are heavy (~2.5 lbs each). Mower requires both batteries inserted to run.
  • Run time: ~45 min mowing (mixed conditions), ~20 min trimming/blowing on high. Buy extra batteries if your lawn is larger.
  • Dual-port charger charges both batteries simultaneously in ~2.5 hours. Single-bay chargers are slower.
  • Self-propel speed is fixed (not variable) – may feel too fast for some users on slopes.

Should You Buy It

Buy this if you’re outfitting a new home or replacing gas equipment on a 1/4–1/3 acre lot, and you want a complete, reliable battery system without mixing brands. Skip it if you already own 40V or 80V Greenworks tools (batteries won’t share) or if you need a variable-speed self-propel or longer run time for larger lawns.
