Type of Job You Need It For

Power of the Chainsaw

If you want to engage in more heavy-duty work, you will need at least a 50 CC chainsaw. Generally, the more powerful a chainsaw is, the heavier it is, so you must be well trained to handle a bulky chainsaw. For professional loggers, forest clearing, etc. a chainsaw with at least a 24” blade is needed. An engine capacity of 50 CC to as much as 120 CC is required.

How Strong You Are

If you have a slight frame, it is sensible for you to get a lightweight chainsaw; get a chainsaw that will be easy for you to control and have little vibrations. It is no surprise that professional loggers are buff people; they need all that strength to handle the more powerful chainsaws.
