EGO Carbon Fiber String Trimmer Review ST1521S

Meanwhile overall I like the idea of the CF shafting I don’t like the foldable bit. Does their auto winder use the motor to rewind the string inside or it is some form of spring loaded. I think Stihl has a new setup that does something like autowind and the motor runs it back.

This trimmer churns through thick grasses and stubborn brush with ease. This had our testers holding the trimer in awkward, un-ergonomic positions when doing smaller jobs. If you want a string trimmer to power through thick brush, this option works great. For cleaning up grassy yards after mowing, though, we advise you to look elsewhere. I originally purchased this trimmer to maintain weeds around my house.

Then press the POWERLOAD button and watch it wind into the head. It winds slowly enough so that there is little chance of the string disappearing completely into the head requiring you to start over. Loading string is now something I look forward to instead of dreading. The EGO Power+ 15” POWERLOAD String Trimmer is just that—a trimmer.

The sturdy build quality, indestructible shaft and quiet brushless motor make this trimmer—dare I say it—fun to use. I know my wife is intimidated by gas powered equipment, and I imagine it’s easier to get kids involved with electric stuff as well. With proper care/maintenance I expect 10 years out of a trimmer. I don’t expect the current iterations of battery operated tools will last 10 years, without factoring for the batteries which probably won’t make it that long either. I’d prefer to have the attachment system and a split boom. The shaft for the end part comes out of a coupler.

The actual model number is the EGO ST1623 and it includes a carbon fiber shaft that extends and retracts 6-inches. The PowerLoad feature automatically pulls the .095″ string trimmer line into the head by just holding a button. The Line IQ feature automatically senses when the line is short, then it automatically feeds out the right amount of line. This ensures that you never run out of line. The former model was $30 less for the kit without the carbon fiber shaft and Powerload head . While more expensive than many residential battery-powered string trimmers, this model has the features to back up the premium price.

One other big change EGO is making is that both the powerhead and string trimmer attachment with a carbon fiber shaft. This is the first time EGO has paired PowerLoad technology with its 56V battery-powered multi-head system. If you’re new to the feature, PowerLoad automatically winds up your trimmer line, saving you the irritation of doing it manually.
