What is it? Mystery Dozer

That headlight arrangement is really reminiscent of IH too. The cable blade hanger sheaves looks tidy. Two stacks - kind of looks like they come from a wye atop the engine but I can't quite make it out

Hi, Dave Tallon.
I have only ever seen one manufacturer other than International make track frames looking like that - ADN/Nord/Acieres du Nord of France from the late 1940s - early 1950s - and they only built one model with that style of track frame, the ADN 130.

The ADN 130 was around D8 2U size and was quite an innovative tractor for its time in many ways. Its big let down, other that parts and service backup, was its transmission. How-wevver, none of the ADNs that I have ever seen had rear-mounted radiators or the square lines of that beast.

Just my 0.02.

The ADN130 ia 6 Roller track frame the pic from dtallon has 7 rollers.

Although the front sure looks like the same design ideas. Could be a different model same manufacturer.

Hi, cohlj2.
I was referring to the general shape of the track frame and the outer track frame bearing - see this photo of a restored TD24 - [attachment=40623]IH TD24 crawler nicely restored_1A_FL.jpg[/attachment]

The inboard ends of the track frame diagonal braces also show a remarkable similarity to the same parts on an early TD24, as do the inboard external faces of the final drive housings where they attach to the back end of the tractor. (I just had the thought that you can't call it the steering clutch case 'cos they had planetary steering instead of clutch-n-brake.)

I am starting to wonder if it might have been an experimental tractor leading up to the first TD24s.

Deas I wonder if it may have been after the TD 24 and maybe a larger prototype

It looks very modern with that grill and radiator up the back

Is it armoured?

Hi, MrsMP.
Pre-TD24? Or post-TD24? Or nothing to do with it? The TD24 morphed into the TD24 42 and 'B' series and then to the TD25B and C and later 'incarnations' of same. Once you add blower fans into the mix, there doesn't seem to be much for or against having the radiator leading the charge or 'advancing from the rear'.except that fans are awful noisy and more so the bigger they get - as anyone who has ever operated any of the Euclid 'TC' or 'T-Rex' '82' series dozers can tell you - - - - IF they just happen to hear you ask, that is..

I DO love a mystery.
