Massey Harris 25 3pt rake

Hi everyone, I have been looking for a set of wheels & tires for the new to me rake, a MH25 3pt rolla bar...

 

The P/O put a set of wheel barrow wheels & tires on it at some point, they are shorter and smaller than what should be on it me thinks..

 

I have been searching the web and haven't been able to find what size that should be on it or anyone that offers them..

 

The rake sits too low in the back now so I need something else..

 

If anyone has a set on a unused rake let me know, or if someone has a manual I'd take that also, haven't found a operators manual yet either..

 

Thanks,

 

Chris
