This is a stretch for sure but, nothing ventured, nothing gained...
Have old (as in late 50s/very early 60s) utility mixer that was mounted on old Farmall 560 w/ the two-point connection system and two other brackets around the rear axles. No longer have the 560; was looking at trying to rig up a mount for either the JD 4440 or little 955 utility tractor (or perhaps even just make a fixed platform and and convert it into essentially a stationary mixer since the cab on the 4440 is in the way and there's not much of any way to mount the solid shaft to the rear PTO to hold the weight and the little 955 isn't much more convenient it appears, but I've not yet totally given it up)
Anyway, the Transmix was/is a 3-pt (or similar since IH had 2-pt at the time) mixer that ran off the PTO using a center hub on the PTO and a tire mounted on the rear of the drum as the driving mechanism. It was on a tilting cradle that let you drive to a pour site and dump there. We used it to pour all the bunks for the feedlots back then.
The point of the posting is while have all the pieces, it's been so long since it used it I can't recall precisely how it assembled and if anybody just out of the blue had access to manual or pictures on an IH it would aid significantly in sorting it out. Can't believe in all the manuals there are here(*) I can't find where Dad must have squirreled this one away...
They were built by an outfit called Universal Pulleys Co. in Wichita, KS. AFAICT they are no more and apparently haven't been for quite some time.
Here's a link to one on a Ford 850; the one here has a different mounting arrangement by enough that that picture is of minimal help on the pieces-parts that I can't quite figure out orientation of as yet to make it work. The cradle that the drum rolls on is similar but not the remainder of the framework isn't at all similar. Part of difficulty is I don't have/know distances and/or heights from the axles, etc., of the
560 so can't precisely locate a reference point to start from.I'm sure eventually I can get it worked out but just took a break and thought would ask -- if nothing else, others might find it an interesting piece of gear...
(*) Like a like-new manual for 1920s Farmall and a Twin City Model 30 or ... :)
