$60 off/$90

As part of the Amazon early fall Prime Day deals, you can score the budget-friendly Greenworks 40V 12-inch Cordless Electric Dual-Line String Trimmer with a 2.0Ah battery down at $89.99 shipped, beating out the brand’s direct website pricing by $10. Down from $150, we’ve mostly seen this model keep above $110 during 2026, though there was a fall to $100 during June’s Prime Day, as well as $90 back at the start of the year. The deal here is bringing back that 2026 low with $60 savings, giving you a more affordable trimming solution. We’ve also rounded up some additional string trimmer deals below, or you can shop all the brand’s tool deals in the official Amazon storefront here.

If you’re in need of a new trimmer that won’t weight much on your wallet, this legacy Greenworks 40V string trimmer is a solid option with it returning to its lowest 2026 pricing. With the included 2.0Ah battery it can tackle up to 1.5 miles of trimming on a full charge, providing a 12-inch dual-line cutting swath. It also features an auto-feed line system, a variable speed control, and a three-year warranty, too.
