I bought an older manure spreader, no name, id or otherwise, has rubber tires, not metal wheels. It is ground driven and looks like several I have seen over the years. It looks alot like the CDT McCormik 100, but not exactly. Size and levers match up, but it is not the same. Finally hooked it up and the chains that run the screw type blades and toothy things work fine. The chain that drives the angle iron to move the material to the blades does not move. I can't figure out where the gear to move that chain is. Is there something internal with the axle? I have been looking on line for manuals or basic pictures of the drive mechanisms. I can attach pictures tomorrow as it is dark now and I have given up for the day.
