Cliff I dont see how a stump could break that easily, pine maybe. I was going off my experience with an old maple stump which is only 7 inches in diameter. I could think I could break my trailmaster with that thing if I had a cheater bar. I just assumed that a 2 foot stump would do the job nicely. But Cliff that flying khukuri wouldnt be a big deal as long as there werent bystanders. The truck would accelerate too fast as soon as tension broke. Oh well, back too the drawing board.....
