sorry to be getting back to you this late.
I am not familiar with this model of tractor, but I might suggest watching Craigslist or Ebay for the part. Worst case scenario, you could check into having a machine shop make a replacement part. Might be a little costly, but then might not be much more expensive than the original part if it was available.
Other brands of mowers might have this part, too, and they may not be obsolete. See if you can find out who made this model for Sears.
