Here is my 1977 Sears 16/6 single ( ST-16) I bought in 2011 that would not start. I had an idea what the problem was, got home and sure enough, no compression. The dreaded Tecumseh OH160 dropped valve seat. The exhaust seat was so bad, it beat the head beyond repair. I found a used head and off it went. Through the years, we've had an up and down relationship repairing things, the head, SSI module that is now a custom ignition, regulators, stators, etc, but she still runs good and is my primary tractor for all my chores.
Below pictures are the evolutionary changes as the years have gone by. The first pic is as it was unloaded from the trailer progressing up to the current condition. Turfs turned into loaded Ags, front tires turned into All trail type and it's "loaded for bear". It mostly is used during the summers for mowing duties, but the deck comes off and then it gets the custom winch set up for my snow blade and the dump bucket. Spring gets the plow/discing duties which will be most of the included pics.
From my first time plowing the garden with turf tires and having no clue what I was doing to know taking it to plow days and rolling some pretty furrows. Even my daughter thought she would give it a shot in her nice slippers...I think not, she is a scary driver. I had let it get in rough shape ( IMO) so this spring it got a Sarah Palin, "lipstick on a pig" paint job; a quick tape off, sanding, then a rattle can paint job. Not the best, but she looks a little better and I slow down some of the rusting. After it was done, I promptly drove 3 hours to Ball Hallow plow day to get ti slathered up in some of that Ky concrete, I mean dirt.
So here it is.
