This has got to be the most outlandish, blatantly false claim by a manufacturer, that I have I have heard in a long time. As a person experienced in brush clearing, I can say for a fact that you WILL NOT clear 6 acres of dense or even medium thick brush with this dinky machine. A person can not walk behind this machine and cover 6 acres in a typical day. You might clear 6 acres, if you are only mowing grass, or brush that is no thicker than a typical twig. However, if the conditions are like those in your promo videos, then no way. Get real guys, this is not a 6 acre/day clearing machine. Heck, Fecon only claims you might average 3 acres/day using their 140HP machine with the 6' mulching head. And, the operator is riding in an climate controlled cab to boot. Lets back off these wild claims and get real.
