The Hyper Tough Curved Shaft 18-inch Grass Trimmer is a versatile, powerful tool. Powered by a 26cc, 2-cycle, full-crank engine, this trimmer is designed for reliability. The full crank engine reduces emissions, increasing fuel efficiency and delivering longer life. The transmission is supported by a vented aluminum casing which greatly reduces vibration allowing you to work in comfort until the job is done. The attachment capable straight shaft is built with a robust aluminum tube and connection point which is lightweight and durable. The tap-and-go trimmer head with twin line cutting system allows you to make good use of up to a 18-inch cutting swath to finish the job quickly.
