  2. Cooler than a Cornbinder tractor, but I would call it a crawler tractor (myself) since there seems to be no hydraulics on the front end as you would expect with a bulldozer.

  3. That is an IH T6 Ag Crawler Tractor.
    For any of you IH buffs, it is the equivalent to the Farmall M, Super M, 400, 450, and I6 (industrial model) wheeled tractors.
    The diesel version, the TD6 as well as all the other tractors, (MD, 400D, ID6, etc,) all had a unique dual fuel engine that started on gas, and switched over to diesel.
    Back in the day, starter motors were limited on power, so many manufacturers got around that by using a small gas pony motor, but IH chose to make the engine run on both by adding an extra valve in each cylinder that lowered the compression to the point that the common 6V starters could turn them over allowing them to burn gas with sparkplugs as an ignition source.
    Once started, the engine was run until warm, and a lever was pushed to change it to high compression and at the same time, diesel fuel was injected, gasoline was shut off, and spark was stopped.
    It worked really well up here in North Maine on the coldest -40 deg mornings.
    I always got a little shiver down my spine when that thing switched over.
