    That's actually the engine. The machine is 9KK04436. It does not appear to have been originally built with AUX hydraulics, certainly none show up for that machine S/No. If you have some photos it may help someone to identify what you have installed.

    Might have just been set up for a thumb, as most of them were. Nige is right, pictures are needed, even of the foot pedal.
