The 570BTS is the working crew's default Husqvarna. Its 66cc two-stroke makes 4 HP and a listed 972 CFM, and the maker calls it commercial-grade and designed for the most demanding professional use. The BTS suffix indicates a backpack with a tube-mounted throttle, which lets you adjust speed without letting go of the nozzle.
It sits in the middle of the Husqvarna pro line, between the 360BT at 890 CFM and the 580BTS at 1000 CFM. The step up from the 360BT is a larger engine and a steadier output under load. The step to the 580BTS is smaller than the price gap suggests, which is why many fleet buyers settle here.
The real argument for it is support. Husqvarna dealers stock filters, spark plugs and carburettor parts for this family, and a crew that loses a day waiting for a part loses money. Run the manual's fuel mix, replace the air filter on schedule and keep a spare spark plug in the truck.
