This Husqvarna gas hedge trimmer has an amazing quick-start engine that includes an air purge feature to omit air from the system. This ensures the engine remains at maximum performance. It has a 25.4 cc X-Torq 2-cycle engine that powers the 22-inch cutter blade and also lowers emissions without affecting the trimmer’s power. The exhaust is positioned away from the user to allow a comfortable environment for completing your desired hedge trim. Blades are powerful and will safely cut through branches or twigs up to 3/4 inches in thickness.
