$250 is a good price for a 100 with fenders on it. On a 100 my top end on one that is unrestored would be 400 with the options you stated on it. They built 39,102 of them and there is still a LOT of them out there even though many have found their way to the scrapper or have been modified into pullers. A 1200 will mow WORLDS nicer than a 100 will and they are not as common as a 100 is. They have a better designed deck, a more appropriate second gear for mowing and are easier to service with the removable tunnel cover. A 100 is probably the #2 tractor in production numbers right after the Original who's production number is 64,867 tractors. Most of the tractors production figures topped out around 25,000 or so. Some were much less like the 800 with 2,345 tractors, the 169 with 4,005, the 126 with 5,247 or the 73 with 7,678 tractors built.
We own all of these but the 169 and the 1200. I once had a 1450 that I started to rebuild but then traded for my 36A snowthrower and some cash. I miss that tractor and now wish I had it back! It mowed NICE!

Well it looks likeI was off on the production numbers, but i knew these 100 were pretty collectable
