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.
Itâs a not a guessing game or a matter of opinion as to what chainsaw you should buy. There are some hard and fast rules to apply and my intention is to clear up some of the confusion with this chainsaw buying guide. A chainsaw isnât a toy, itâs a tool used to cut wood so knowing your needs is the first step in the process.
