Hi,
They are different lever assemblies. Below is a page from the Cub 193 Plow owner's manual showing parts for it, there isn't an assembled pic that I saw.
Hi,
radioguy41, that looks like it is the depth adjusting crank on the LoBoy, for a Fast Hitch. Does your LoBoy have the rest of the Fast Hitch.
Below is a page from the Cub parts manual showing it.
