Field mowing....

stihl makes a weed eater type of machine called a sickbar mower it is like a weed eater only there is not the spray of weed juice. You want to be real careful as some weed are very toxic and can burn your skin and scar you. This tool is simmilar to a hedge trimmer only much heavier duty and will cut small diamater trees and brush. Take it down over time dont kill yourself do a little at a time clean it up and maintain it. Or just hire it out and let the professionals do it. For what it will cost for all the equipment you could have it done for a ton less. People are hungry for work and money. Bill
