Is this a one time job, or will it be an on going project ? If you plan on this being an on going project, I would highly recommend a Farmi logging winch.
I heat my house with an outdoor wood burner and pull logs out for use as fuel. I had my place timbered a few years back, and had the loggers leave the tops in place, as at the time I heated with natural gas, and the tops make good ground cover for game animals. I started pulling the tops out for use as firewood when I got the woodburner. I started using my tractor and chains, but found I could not reach/get the proper angle of pull on a lot of the tops. I then purchased a Warn M8000 electric winch (8000 lb pull) which worked well, but had the following limitations
1. 80ft of cable meant still having trouble reaching some of the logs.
2. Due to the high current draw, I would have to rest the winch on long/heavy pulls to prevent the winch from draining the battery/over heating.
3.Having to pull as straight as possible to avoid the cable balling on one end of the reel.
4. Having to winch the log in, unhook the line and turn the tractor around to drag the log out attached to the draw bar.
I recently purchased a Farmi logging winch which has made the whole process much easier.
1. I can now winch out several logs at once.
2. I have 165 feet of cable giving me a much greater range.
3. I can pull in a 30 degree radius without the cable bunching.
4. The winch is driven from the PTO so no worry about draining battery/overheating.
5. Winch mounts on the 3ph so after winching the logs in I can just hook the chains to the blade on the winch and pull them out without having to turn the tractor around. This also allows me to lift the ends of the logs enough so a sled is not required.
