allis chalmers tractor

[schalfback]

I have a 712S tractor. Looking at the rear it appears it has two what could be hitches. One has linkages going to it like it is for a lift set up for maybe a plow etc. Does any one have a 712S with this set up? Any info would be appreciated.

What you are looking at is a unique type of 3-pt hitch similar in use to a CUT, SCUT, etc. The round tube at the top provides the "lift" for rear attachments, rather than simply a toplink on a CUT/SCUT. The bottom hitch points hold the attachment in place, and work like sway-bars or stay chains to keep if from swinging side to side. You can get what's called a "sleeve hitch" or a "Brinly hitch" that pins into the bottom two points and allows use of common aftermarket attachments such as moldboard plows, cultivators, etc.

Suggest you go to http://simpletractors.com -- a site dedicated to these old machines. You can find out all kinds of helpful info there including all the attachments for them, ways to get manuals for them, etc.
