I bought 50 acres last year and started a trail for hiking and jogging around the perimeter. For my purposes, a Stilh brushcutter combined with my chainsaw worked very well since I had mostly thorn bushes and small trees. I can wind the trail around the larger tress and cut out an ocassionaly samplings of 3 or 4 inch diameter. Part of the trail is too sloped for my riding land mower or a tractor and has rocks on the slope so brushcutting is the only answer. For the remainder of the trail, I have used my riding lawn mower and after many mandrel replacement, I realize why they call it a riding LAWN mower. But I am afraid of rolling over the tractor.
This project it about 75% complete, almost ready to start the bridge over the small stream. Good luck, Remember making a pth it is healthy workout, not work!
