Harry Furguson Tractor or combination of ...

I'm looking to buy what may be a "Harry Ferguson" tractor, but
there is no documentation on it, nor does the person who inherited
it know exactly what it is... Model, tear, etc. Above the steering
column there's a plate with the name "HARRY FURGUSON"? Detroit,
Michigan TO-32675. On the left side of the Differential it has TO
4013-A with 208 beneath it. On the right side it has TO 4012 with
233 beneath it. On the housing of the shifter it has HF then below it
TO-T006 or maybe a 5. The housing under the seat has HF then
below that TO-4-24 and below that 104-A. The Engine is a straight
4 with a firing order of 1-3-4-2 and an Engine # Z120A600 then
below that 00 and below that CIY? The Steering Box has TO-3550-
A. Now it gets interesting... there is some kind of rectangular frame
that runs around the lower part of the whole tractor with a plate
that states: SKYLINE PRODUCTS (Skyline Manufacturing) Wichita,
Kansas. Model # 90-15-51. Serial # 5660?
Can anyone make sense of what all this is? Or means? It appears as
if it is parts of different tractors priced together? Or perhaps these
are the independent #'s associated with the specific part or item it is
stamped on... Any suggestions? Thanks ; )

to the left of your pic go to serial numbers. that will give year info.

appears to be TO-20.

That is a 50 model TO-20 from the serial #. Appears it's missing the hood...

The box frame is part of the FEL, what it mounts to.

That is not going to be a real powerful loader. Without power steering it's going to be hard on driver and tractor. If it's been used much, count on having steering gear problems.

Yeah those are a bunch of part numbers. The engine being Z120 tells us it's a TO-20, as that is a Continental (120 cu in) engine.
The frame is someone's retrofitted front-end loader.

With all the color looks like one of tony's children.
