I have, from what I can glean, a 175 bucket loader. My problem is that the previous owner, now deceased, cut a cab off of it even with the dash. It had a black plastic in cab shield, similar to black rv pvc, and I am wondering if this was to protect the used from an incab hydraulic line failure (skin injected with hydraulic fluid). I cannot find any ID plates on it and I think they were cut off with the cab. It has the 175 C counterweight at the rear, and Dresser on the front at the radiator, but had IH stickers on it when I first got it about ten years ago. one of the things that is driving me crazy is that the fuel tank is completely square, not rounded. Any info on these concerns would be appreciated.
