Joe and Joe, thanks again for the compliments. The rear hubs are off a wheel horse, such as a 854, and later models all with a 1" axle. The engine is a Tecumseh TVXL 220 and was rebuilt and tricked up a bit by a guy that builds go carts. I did a repower thread on it a couple years ago and was pretty much a straight forward swap. Tom Ingels, thanks for your quick response a few weeks back when you answered my axle size question. Raising the fenders was a bit of work. I drilled out all the spot welds to remove one side and used a cutoff wheel on the other. I cannot say one was easier than the other. I then welded in new sheet metal from the tire side to plate in any existing weld holes.I raised the fenders approx. 2" to clear the tires, rewelded the fenders at proper height, not much clearance from tires, and duraglassed /molded in the fenders. I could of done it without molding the fenders but I liked the way it looked.I used the little 70 to pull some large tree logs around before I painted it ,to see how the bigger tires worked and it did quite well ,but still can spin the 23x10.50 tires with no problem. A set of wheel weights may be in order.I actually use this tractor quite a bit due to it's power and very tight turning radius to rake leaves, roll the lawn, trailer duties, ect. I even pull started a four cylinder jeep with it out in the street and it had the power to pull the front end up but did get the jeep running after pulling it in high gear around 200 feet.Tom Ingels made a comment awhile ago that he had a friend that pulled a model 70 with the stock transmission and it did well per Tom.That is why I persued this project. I feel that the trans. will take alot of abuse. One more thing I would like to add is the hitch being 21/2" higher does wonders for attachments and the tractor is not nearly as prone as it was to doing wheel stands when pulling heavy loads or loads with alot of tongue weight.
