I had a few transaxles a while ago ,one I think was a 820 off a MTD , I offered them for Free on Gumtree and no one was interested and they all just went to scrap metal.
Had a lot of good ride on mower tyres ,some were new ,offered them for free and someone drove 2.5 hours to get here to pick them up.
If it's for a buggy ,it may just be easier to find a Free complete ride on mower as I see them advertised a few times a year or buy a Cheapie as I see good running ride on mowers and they are usually selling at a minimum of $50.
