Depstech make a good reasonable one, works well, takes video and pictures
I'm pretty sure the muffler and elbow was mounted. I think it was pretty much, pull it out of the box, bolt it in the tractor, install the PTO and S/G, and put oil in it, and it was ready to go. It would have been a 2-3 hour operation from fully assembled tractor, to r&r and back to a running tractor. Ours took a couple weeks, because while it was down, and waiting on the engine to come in, Dad repainted the tractor before reinstalling the engine. There are pictures of this tractor as it looks now, here on the forum. I know that I have posted a few......That is certainly possible Harry, either at the dealer (low man on talent totem pole assembling crate motors), or the original purchaser was to assemble. Scott, any memories on that theory?
