Experts say the Shindaiwa T2510's hybrid engine combines the best features of four- and two-stroke engines. Like two-stroke engines, it's lightweight, but it's also fuel efficient and has lower emissions than two-stroke engines do. It is designed for commercial use, but suitable for a homeowner who needs a powerful and durable trimmer for tough jobs. It features a Speed Feed system that allows users to reload line in the cutting head in less than 30 seconds. However, this string trimmer is very expensive.
