Re: Clearing Underbrush
With higher quality string trimmers you can replace the string head with a blade which will cut through nearly anything you put it to. The weed mower aforementioned is also an alternative, though I don't know how well it would work on larger woody things like sucker trees and such.
Do be careful when clearing poison ivy and things of this nature so that you don't get the oils of the plant all over yourself or your equipment. Don't burn "poison" brush because oils and resins will be in the smoke and if inhaled can cause serious problems for you or anyone else that comes into contact with it.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
