Believe made in Canton, Ohio.

Believe manufactured from 1897 to 1950 (drop center rims, with modern tires and carriage).
Gearbox (patented 1920, by Mr. Haymaker, of Canton OH.) is a beveled gear, with pinions on each side. Sliding the apron control level, is forward, neutral, reverse, which engages the beveled gear on either side. Chopper/blower is the same principal (rotating fan, with chopper knifes), that was used to fill silos, and the later, pulled silage chopper (Fox comes to mind).
Scarest moment in my life was at about 17, my neighbor had me slide along the top edge of a steel silo, that had 1 1/2 angle iron, on top, seeing the empty silage one way, and the ground about 60' below the other way, carrying a pulley and rope (no safety harness). to attach to the top of the silo, so he could pull the full pipe and shoot up to me to secure it to a chain on the silo..
The silo filler was similar to this, but without the chopper knives. The big tractor (JD 60), dulled the Fox, one row chopper, blowing the chopped silage into a 4 wheel wagon with wood side and a tail gate that swung open over the feeder apron (hinged apron then, so you could drive straight thru). An electric motor was attached to roller to move the lopped chain, on the floor of the wagon, and I used a right angle fork, to pull the silage down evenly to fall in the apron, and hope I didn't, get a "WAD" to plug the blower pipe.
This Blizzard 600 chopper-silo filler, worked in conjunction with a corn stalk "Binder" and all the handling, transporting, loading to apron, was by manual labor (neighbors).

I remember that we had a Blizzard 600, a 500 and a Papec at one time or another. Both of our Blizzards self destructed when the shear bars broke. Both of them had a lot of miles on at the time. Still, I'd advise you to keep a close watch on the condition of that shear bar. Ours never looked that good. They both had a universal one color paint job. Sweetfeet would love the color. It was rust. Pop bought a Case forage harvester in the late 40's-early 50's. The Case was basically a ensilage cutter with a corn or hay head instead of a table and from that point on we used the ensilage cutters to chop baled hay for bedding.

Over the years we used 6 different tractors to run the things. Olivers OC-4, 60, 88, S88, Farmall M and an Allis WC.

Thanks for the advice on the cutter shearbars. I checked them over and there was no nicks or bends and thrust bearing on fan appears good. I noted that there is some adjustment on fan knives, but have no idea of spacing, Felt like about .020, which appeared okay when I gave it a test run , at full throttle on a 1951 DC case. Good balance on fan.
Know what you mean on "self destruct" choppers. Neighbor ran a leaf spring , from the windrow, thru one. Took out the whole PTO drive, rated at over 150 HP. plus all the knives and shafts. Hopefully this one is semi retired to "Demo Only", and will not be shoved to the max, like most.

Yeah. Ran a ball peen hammer through my S-717 one time. Forgot to loosen up the slip clutch and free it up before starting chopping. Took out the shear bar, 4 knives, and 3 knife carriers before a u-joint self destructed. Ripped the pan to shreds, too. Expensive mistake I didn't make again.
