It's PTO driven and has about 11,000lb pull capacity. The specs are on a few Farmi dealer websites. The 501 is "medium duty" with a 1/2" cable. I found it difficult to drag out hard-to-reach blow-downs with chains attached to the tractor. These logging winches (there are several makes available) allow you to lower the blade which anchors in the ground while the cable pulls the log. Once the log reaches the blade, you attch the skidding chain to the top of the blade, lift with 3pth and go.
The reason I'm posting is because I looked up every post on logging winches and see there's room for more pics and info. It's an expensive tool and before I committed to buying it, I wanted to read every post and see every pic about it. I walked every inch of my land and assessed how much use I could get out of it and possible other uses. I'm brand new to this, so there's plenty to learn. So for what it's worth, I'm glad I went for it. Another consideration for those of you thinking about it...these winches have few moving parts, are easy to maintain and are reliable...and they will last you until you're too old to ride your tractor! If any of you out there are experienced users of logging winches, please share some useful tips, past threads, pics, or war-stories that your wife's tired of hearing about! /forums/images/graemlins/smile.gif
