c-28 hay mower

[redgems]

Fellas,
Does anyone here have a C-28 fast hitch mower.
I believe I have one but can find no literature on it. Most of all I see are the #c-24's.
The difference I see is that my V belt angles out to the left (Standing behind machine) and the #c-21 & 24 do not.
Any help appreciated!

Here is a picture of mine. Sorry, I don't have better picture at this time but notice that my pitman drive is to left of top pulley and all c-21& c24's are straight top to bottom?

Adjust the fast hitch so the PTO is reasonably in line; it looks to be off to the right too much.

I did get the clarification.
Its a U-F-28 made 1955 + Was made for 300 U & 350 U's and 300 & 400 Farmalls.
Reason for drive pulley being off center to the left was to accommodate the lower stature of the Utilities.
I found a 300 &350 U equipment manual and a former sales person on another forum confirmed.
Looks like we all learned something. LOL.
