The Wheeled String Trimmer is a powerful, agile grass and weed trimmer that can tackle the toughest of jobs. The 22-in. cutting path with 5 cutting heights from 1.5-in. to 3.5-in. can easily take down waist high grass and weeds with no more effort than mowing your lawn. Plus, it can trim inside corners, edges, and against fencing and posts – places a traditional mower is unable to reach. The Kohler XT675 149cc EPA/CARB approved 3600 RPM engine with an automatic choke provides easy starting, reliable operation, and a long hassle-free life. The unique trimmer ball design with dual 4-in. heat treated blades helps you tackle tough and woody weeds with ease while the 14-in. wheels provide a perfect center of gravity allowing you to operate on uneven terrain with remarkable maneuverability. User-friendly while being tough on grass, weeds, and brush.
