I recently purchased my parents 5 acre home. Two acres are mowed, two are wooded, and one acre is full of cedar and thorn bushes. Id like to thin out some of the cedar and remove the thorn bushes, but what is the best way to get rid of brush that is as tall as a man, and several feet wide and several feet deep ? I thought of using a chainsaw on these, but to be honest, Im the kind of person who you would read about undertaking such a task and than ending up cutting off his arm. Any suggestions ? Would a chainsaw actually work?
