Allis Chalmers identification

[capriguy]

When I was young, my father bought a brand new AC tractor and I would like to someday get one like it to restore, but I don't know what it was.
Here is what i know
Purchased new at the AC dealer in Montevideo Minnesota.
My father died in 1977 and the tractor was purchased 2-3 years before that.
Diesel, no cab, big rear tires, wide front end, square rear fenders with 2 headlights each.
I do not remember there being a 3 point hitch, but it did have live PTO and hydraulics.
I received a large diecast toy tractor that was the same exact model as the real one. The toy had a weight bar and plastic counterbalance weights but the real one did not.

Any clues?

Was it one of the 100 series? Here is a 170

That sure looks like it! Are there any websites or good books available so I can read up on the specs of this?

TractorData.com - Allis Chalmers tractors sorted by model provides specs on AC tractors, although some of their data are disputed IIRC.

TBN has a forum devoted to vintage tractors -- General Vintage Tractors - TractorByNet.com . There are some knowledgeable AC fans on TBN that can help. (I'm an AC fan as I grew up with a WD45 and a G, but I fall well short on the knowledge front. )

Here's a forum devoted to AC -- AllisChalmers Forum

Good luck.
