What is "New Photo" section ?
It works slick. A chainsaw dulls down with one close to the ground cut. Being able to grasp the tree to extract it from a grove and carry it out, high if necessary so it goes on a burn pile, is a real plus. I do have to get off the tractor to line-up the trunk with the jaws for grasping.
If I was doing it over the basic backbone tube that the blade hinges on would be heavier and the stationary anvil blade would be reinforced to resist upward bending - a 10 - 12 ft. tree as it falls has a lot of leverage /forums/images/graemlins/shocked.gif Also. a 3" diameter hydraulic cylinder would be plenty strong, a little faster and cheaper. As it is, I got over 30,000 lbs of force. The tractor doesn't even grunt.
