What owners like and complain about

Greenworks Pro 80V 18" Chainsaw

  • Street price of $210-250 for a complete 18-inch 80V kit embarrasses saws costing twice as much
  • 42cc-gas-equivalent brushless motor handles 18-22 inch trees per Lowe's owner reports
  • 2.0Ah battery recharges in about 30 minutes — faster than most competitors' packs
  • 4-year warranty on both tool and battery, double what Stihl gives its battery saws
  • 4.6-star average across Lowe's reviews with consistent praise for quiet, instant-start operation
  • 2.0Ah pack is the runtime bottleneck — about 110 cuts, and big hardwood drains it fast
  • Recurring owner complaints of chains loosening and derailing without frequent tension checks
  • Heavy bar-oil consumption; owners report topping off constantly
  • Bogs when forced in logs near the bar's 18-inch capacity
  • 80V batteries are pricey if bought alone, which weakens the ecosystem argument

Greenworks 40V 16" Brushless Chainsaw Kit

  • Complete 4.0Ah kit at $300 undercuts most 16-inch battery saws from name brands
  • 9.28 lb bare is light enough for sustained overhead limbing
  • Narrow .043-gauge chain keeps the motor from bogging in small wood
  • The 40V pack runs 75+ other Greenworks tools, including their mowers
  • Tool-only version (2006002AZ, about $180) exists for owners who already have packs
  • 120-minute recharge is double what Greenworks' own 60V and 80V kits take
  • 16-inch bar oversells a 40V motor — big hardwood bogs it
  • .043 chains are a narrower aftermarket than the .050 stock every shop carries
  • 3-year warranty, not the 4-year the 80V line carries
  • Greenworks reuses SKU numbers across generations, so parts lookups and used listings get confusing
