The TB252S gas string trimmer features a 25cc, 2-cycle lightweight engine for ease of use. It comes with a 17" cutting swath to cut wider areas of grass in less time and SpringAssist™ technology for easier pull starts. The dual- line bump head with .095" line allows for precise cutting, while the straight shaft trimmers reach more easily under shrubs, around fence posts and other obstacles. The multi-position adjustable handle reduces vibration and operator fatigue.
