In the mid 60's I worked at a canning plant and drove an AC tractor with a similar arrangement. It had a skirt completely around it that was raised and lowered with the 3 point. We used it to push sweet corn off the unloading platform into the conveyor system that carried it into the plant.
Until then, all tractors were Steam and a bit dangerous and likely to start fires.
This one wasn't successful, but a few years later this model was the start for Waterloo Boy which was the start of John Deere Tractors when JD bought them.
This is a great looking, compact, powerful tractor doing some plowing. What I find interesting is the guardrail beside the seat. It's almost as though it's there to keep the driver from falling off over the rear fender.
This one is interesting in that it has a REL (Rear End Loader) and is articulated. What makes it interesting to me is how much of the tractor is out past the front wheels and the fact that based on the angle of the stering column etc. I have a feeling that it is not hydraulic steering. Could be wrong about that part.
It's wierd, but on that last one, I get an error in Explorer, but if I go to the address line and just hit return, then it comes up. I've seen that before. Pretty strange (as in the tractor)
