Yes tractors are very useful for pulling cars around. I found my M Farmall could drag cars around better than my WD45 Allis Chalmers even though the Allis is rated at a little more horsepower. The M weighs more so the WD45 will spin out before the M. My buddy has all the Farmall letter series in spades. I remember he was trying to buy my M off me over 20 years ago, told me if I ever wanted to sell it just to let him know. At the time he had 17 M Farmalls alone, he had tractors in all the letter series then and he hasn't let up buying. He is always bringing home another tractor. A couple of years ago my neighbor that was a big IH collector sold out most of his collection. My buddy bought 21 tractors at that auction! Since my place is only 2 miles from the sale site we proceeded to bring tractors over to my place. I ended up with 12 of them out by the garage that day. My wife was a little worried that he would leave them here forever but he did a good job of moving them home, I think the last one was here 3 weeks. She remembers that pickup he left at our place for about 10 years. I really enjoyed driving the M-D diesel Farmall home from that sale that day. Dad had a 400 diesel when I was a kid that I remember playing on. He traded the 400 off on a new 4020 John Deere in the spring of 1965. I took a video of the trip home. My buddy is the guy being pulled by my brother in the video. My brother is driving the single front wheel M Farmall dragging our friend behind. I also took a video of the twelve tractors at my place that day. It was a fun day!
