I'm not too sure.

There is a small aluminum(?) header tank sitting up near the top of all of the mechanical stuff with a red threaded square on the lid.

That tank is right empty and we are not able to engage the drive on the machine.

I assume since there is no fluid in there at all, that is where the leak is from.

Can I put the same hydraulic oil in there as in the main tank or is this strictly DOT5 brake fluid?

Thanks again!
