The TB252S gas string trimmer features a 25cc, 2-cycle lightweight engine for ease of use. It comes with a 17 In. 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. Its TrimmerPlus attachment capability allows for more versatility and less storage space. The multi-position adjustable handle reduces vibration and operator fatigue. Includes 2-cycle engine oil and a 2-year limited warranty.
