It has defo had some modifications before I had it I think the engine had been uncovered and a few bits have been welded on, thanks for the conimation. She had lost a little power and started blowing black smoke, any ideas o that?

I have my self a little dumper, it's benford, I think but I can't find an exact match to it, it's almost the same as a tf50 but the engine different than the drawings. Is there a model ID plate on the machine some where? And suggestions would be much appreciated. Thanks all
