I once had a 250 which I had 2 different loaders on, but I sold it about 8 years ago. Here is the only picture of it I could find. This is the second loader, a MF30 industrial, which was really too heavy for the tractor. The first loader was an old MF pipe loader with trip dump bucket. I plowed snow commercially with both loaders, and beat up the pipe loader pretty bad hitting curbs.
My uncle, who is a master welder and fabricator, rigged up the pipe loader for me and I did the industrial loader myself, using his mounting brackets. Both loaders had to be narrowed to fit the Belarus.
There are three sets of mounting points for the loader frame:
1. Front: a pipe slid inside the front weight hanger bracket.
2. Centre: a large heavy-gauge channel with brackets welded to it to bolt onto the bell housing.
3. Rear: a pair of brackets bolted onto the rear drawbar mount.
For hydraulics, I used the spare tractor spool for the boom and plumbed an extra valve in series for the bucket (no power beyond...and no problem in operation).
Sorry, I don't have any other pictures. I hope this helps.
