Thanks for all the compliments. The Sthil saw on the winch is a 064 that my uncle gave to me about 15 years ago. Before that, he used it to cut timber. It still runs as good a new one. In my opinion, you do not own a saw unless it is a Sthil. As someone mentioned earlier about the clutch, there is no clutch on this since it is pulled with a hydraulic motor. If the pulling resistance outweighs the pulling force, the pressure releif valve on the tractor opens just as it does on a loader when you try to lift too much. I originally was going to pull this with the PTO and slip clutch, but I would have needed to created a lot of linkage and it would have not looked as clean. The blade serves two purposes; First, I can sit it on the ground when winching. The weight of the pull burries the blade into the ground, which makes it very stable. I dont have to lock the brakes or anything. Just drop the winch on the ground and go to town. The other reason is to clear brush out of the way. I like to get as close to the tree as possible to limit the amount of cable to pull out.
