I went to see an old friend that lives out in the boonies in southern MN, and picked up a couple of mowers with possible potential. I got an 8237, and I got a 7268. The '68 appears to be a 1981, and the '37 appears to be a 1978. Anybody think these are worth a little time and/or money? I usually gravitate towards the Duraforce models, but I didn't want to see these in the scrap metal pile. Should I or Shouldn't I?
