The stratosphere (/ËstrÃ¦tÉËsfÉªÉr, -toÊ-/) is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere. About 20% of the atmosphere's mass is contained in the stratosphere.
The chainsaw is a highly effective and efficient tree and branch cutting power tool. It works with an engine, referred to as a power head; powering a metal chain, driven by a centrifugal clutch, with a chain moving around a groove in the guide bar at fast speeds.
Husqvarna makes great chainsaws, and they donât seem to slack in the brush cutter department either. Itâs a little pricey, but weâll take it over the equivalent dealer only Stihl and RedMax. The Blue Max is a bit of a beast with a good Horse Power/Dollar ratio. Bicycle bar handles and a lot of motor for the money.
