This is an EGO Power+ 15" POWERLOAD string trimmer with a 2.5 Amp-hour 56V Power+ battery and a 210-watt charger. The POWERLOAD feature automatically winds trimmer line into the head.
In addition to the POWERLOAD feature, this trimmer features a brushless motor, two speed modes (HI/LO), and a variable speed trigger to control the head RPM in either mode. The trimmer weighs 7.6 lbs without the battery. The 2.5 Ah battery adds another 2.9 lbs and provides up to 45 minutes of run-time.
The ST1511T kit normally sells for $220; this one has only been used a few times and is like new. All manuals and extra trimmer line are included.
