I started clearing 5 or 6 acres of hedge, locust, and cedar trees around one of my ponds last Fall. Here's a link to a thread I started last year to document the process. I hired a guy to
cut the trees with a hydraulic saw mounted on the front of his skidster. He made the tool himself. Pictures of the tool are posted within the tread. My memory is that the acres were completely
cut in around 18 hours at a charge of $65/hour. Of course I have lots of additional time of my own cleaning up the spoils, burning etc., but I couldn't afford to pay someone to do the job to completion. I use an Bodozer grapple on my L5030 Kubota.

I've been moving the brush residue with my tractor and grapple, cutting and salvaging fence posts and firewood, burning the brush tops etc. Project should be done this winter.
