Calvin,
I too have been watching this discussion and find it very interesting. My 169 has the original 13 fin 16 horse motor. IMHO, I feel the 169's are neat tractors whether 12 or 13 fins. I had a second 169 that I sold and it too had a 13 fin block. It would be kind of interesting to know what actually happened in the factory when they were assembled. Some of the 169's came out of the factory with manual lifts because they ran short of hydraulic lifts. This to me is also neat info. If a person was going to spend some extra cash for a 169 vs. 149, you would think they'd want hydraulic lift
One of the biggest thing that kills a kohler prematurely is the lovely grenade gears. I've see a lot of K341's with that extra window option:biggrin2.gif:.
I, too enjoy following the discussion.
