I was going thru my Photobucket pics and ran across this pic and thought some of you would like to see it. 1956 Caterpillar that Scott and his dad rebuilt, the whole machine weighs 110,000#, the blade is cable-operated and I think it weighs 10,000# or ten tons (don't remember which). I asked HOW did you move the blade on and off, he said "like the Egyptians- with rollers". They took it to the Erie county fair one year on a hot summer day, hiring out a big rig with over- width capability, there were grooves in the road leading into the fair from the load. Scotty LOVES big equiptment and is always telling me about this little dozer or that one I should get. I say NO- I am going SMALLER, how much smaller than a motor bike can you get? Oh, the dark covering the front of the dozer is from the exhaust plume on start-up.
