Best I can tell, that's a quick attach mule drive mounted to the frame which the 100 didn't come equipped with. Also noticed that the front deck hangers appear to be home made. I'm not home to take pictures of the correct set up, I'm sure someone will chime in with what you need. Found this picture on my phone of my 100. Has the pin on style mule drive that was used up to the 123. The QA mule probably hangs a little lower. Looks like a nice 100 with the hydraulic lift and creeper gear
