Yesterday my sister's b-friend calls me up and asks if he can bring this big old tree stump/roots to my house for pick-up (his town won't take it). I said sure, and he told me that he may need my truck as an anchor point for a come-along to get the stump out of this little utility trailer. Well, he pulls up (he's got an '06 GMC full size pick up) towing a little trailer with a stump that's gotta weigh 600-700 pounds. The trailer was one of those ones with a wire mesh tailgate for loading ATVs and things. Anyway, we decide that we'll just hook the stump up with tow straps and pull it off the trailer right onto my curbside. I get in position and begin to pull. I move it about 3 feet and then start to spin (turns out one of my tires was on the grass). So I put it in 4hi and begin to pull again. This time no problem, I hear some scraping and banging (I figured it was just the stump making noise against the trailer as it was being dragged). I get out of the truck and the stump is curbside and my sister's b-friend is just looking at me. He said that the stump was getting hung up in the wire tailgate and that at one point I was pulling the stump, trailer, and his pickup backward!! Granted it was probably only a very short distance, but damn, I didn't realize how torquey these things were. Anyway, he was pretty impressed.
