Bill, we were not sure of your treesaw until you demo'd it for us its all you said and more. We are custom cutters and we push all attachments to the limit. The perfect tree saw has surpassed every thing we demanded from it. Our fuel costs are lowe, r less wear on machines and productionis are better. After running one for a week we bought the second saw. Thanks for a great product. We will recommend it to anyone!
