Product Description:
Changing the game of lawn care, one yard at a time, the GT Revolution is 3 lawn manicuring tools in one. Converts almost instantly from a trimmer, to an in-line wheeled edger, to a mini-mower, so you get a professional-looking lawn that’s easier to maintain and costs less time and money. This is so much more than a weed-eater. It’s a Revolution. At less than 6 lbs, and with a telescoping shaft, 7 handle, and 6 rotating head positions, almost anyone can comfortably use the Revolution. The shaft is a full foot longer than the original GT, and the grips are ergonomically designed to give the user a firm handle on each of the three functions. And when you want to switch from trimmer to edger or mini-mower, it’s just a push of a button and a turn of the head. No tools needed. It’s powerful, too! Spinning at 7600 revs/min and running on the same 20V 4.0 Ah Powershare battery that powers our chainsaws, the GT makes nice, clean cuts. The patented Command Feed system gives you fresh line whenever you need it—no bumping or auto-feed. With an extra spool holder right on the handle, if you do run out of line in the field, you can just pop in your extra spool without a trip back to the shed.
