Stihl FS 550

fantastic power its got real grunt when you need it – ive owned the fs 550 for 12 years before that i had a fs 106 i have to clear two blocks of land annually for the fire season the 550 does it 3 times faster than the 106 because it doesn't bog down in the thick stuff i use a 3.2 mm thick nylon twin line and it ploughs through just about every thing on shrubs and thick brush i use the metal 3 pronged blade it just smashes through and its fun to use with all that power if you can afford one its well worth it reliable powerful expensive
