Eric. You have a model 100 Case loader. The 100H had a hyd bucket control. Take note of pic#2, it shows the spring and chain assy. and hoop that resets the bucket after dumping it. (simply raise it up after dumping it and it snapps the bucket back to the loading position, while returning to refill it. At first I thought the hoop was also the support when the loader was detached, but doesn't appear to be the case. I see no usefull function for it on a 100H loader.
