Guess I will come out of the closet and throw my 1977 Sears 16/6 single in the ring.
After inheriting my 68 SS12, I began looking for a tractor I could work with while restoring the 12. Found a guy about 45mins- hour away had the 16. Said it quit running after they had been using regularly to cut 4 acres of grass. When I got there, he said it was getting harder to start until it finally quit running, it was his brother's tractor, he didn't want it back and current guy didn't have time to mess with it. Thankfully, I had been reading about some problems with the OH motors, kind of knew what maybe wrong, so for $150 I loaded her up and drug it home, also came with upper 3 pt mount.
Got it home, after a good washing, charged battery, spun it over....turned over well, had spark but wouldn't start. Borrowed a compression tester from a buddy...nothing which was my original suspicion.
Started pulling the top end apart, just as I thought, exhaust valve dropped out of head, but bad for me, it beat the head apart....ebay here I come. Found a used head for $100, threw it back together and back in business. Needed new battery, carb rebuild, general maintenance, but ran pretty well and cut some grass. Used it well for grass duty, plowed/disc garden, then built a custom mule drive winch mount and snow blade along with a dump bucket and added Deestone ags. Was my go to tractor for all duties.
Then forward to Summer of '12, I start getting intermittent stalling. Let it sit for 5-10 mins, fire it back up and back to work. This happened 3-4 times until finally nothing.....Oh no the dreaded SSI module failure. No prob, had a spare from my other ST16. DOH, that one last a month too. So now what? Do I buy a used evilbay one, do the Dale- Overnight solutions fix, Ed Stoller's conversion? Buddy of mine Jon from MTF told me he had new ignition in works, he ended up using a trigger pickup used on the Kohler pulling tractors with a magnet mounted in flywheel. Swapped his parts on my tractor to use as test mule, I cut the waist high field for 2 hours straight, she never missed a lick. I was convinced, bought all my own parts and she runs better than ever up to this day. Mine was the first official Sears with a Tecumseh OH160 using this system, another guy on MTF has just did the same. So, One more option for the SSI failure problem.
I'm still looking for a new regulator to handle my battery ignition and the winch as I've went through 3 regs as of now, running a GM alternator to keep battery charged and tractor running. So she is still my go to tractor, snow plow, dump bucket, plowing gardens, mowing, and the SS12 is on a rack in the barn..maybe someday!
Bring home day
What a difference with just a bath
The custom ignition pickup and coil
Garden work trim
And most importantly.....mowing duty. Funny, my son gets all the mowing seat time
