I got off to a shakey start pulling a 24 inch log about 50 ft. long that I had cut out of a pile and limbed it. I put the choker cable around it, hooked up to my tractor, put her in 4WD and gradually took up the tension while I locked the differential. The log started to move readily and pulled fine for about 3 ft. and a big branch got hung up in the pile I was pulling it out of and all 4 tires dug in. A quick persuasion with the Stihl O-66 fixed that and I was able to pull it free. I was surprised how well the choker worked and how the tractor pulled a log that big (had about 1/2 a cord of wood in it) Just have to take it slow and easy and be real gentle about setting the differential lock. Sure makes cutting up tree in a pile easier. :thumbsup: :cowboy:
