Matt D - that's a terrific story on your 125. Must be something about that model. I have an old friend that when he was a kid, used to walk by a CC dealer on his way to school. At that time the dealer had a 125 in the showroom window and he really liked that tractor. Well dealer sold the 125 but my friend thought he new who got it. After he grew up he eventually got what he thinks was that same 125. I can't say if it was his favorite because he eventually collected 2 models from each series and built his own CC museum in Mass. He moved and the museum is gone now, but you got me wondering if he kept that 125.
Levi - geez, you took a pretty big risk taking the 1450 with that spreader on that maiden voyage. Glad you apparently made it all the way to where you were going
Hope you can figure out your charging issue. I'm kinda wondering if the wiring has been done correctly. If you just went with the way the wiring was done for the incorrect K301 engine you should really investigate if it was done correctly. Especially since the original 1450 wiring was not set up for a V/R and S/G.
Also, you mentioned your replacement K321 engine had the old style PTO. I assume you're not planning to use the PTO since the 1450 doesn't have a lever to engage/disengage it. The PTO will be engaged all the time you're running your replacement K321 engine.
You also mentioned your replacement K321 came out of a model 147. That version would have had an oil "level" dipstick on the left side and an oil "fill" stick on the top of the engine. I don't believe the stick on the top can be converted to an oil level dip stick because the balance gears are in the way. I am wondering if the oil level stick on the side of the engine clears your frame ok.
David S - I see Jason found out the letter "s" used as a suffix just means it's a Service Part. But that sorta sounds like the standard corporate response to a question (or maybe even a smoke screen). I wonder if Charlie might be able to give us some "inside scoup". Seems to me adding the suffix letter "s" to only some part numbers had to have some added cost to Kohler and their suppliers, etc. Doesn't seem like differentiating a "service part" from a non-service part would be a required marking for a part number. And besides that, I'm fairly certain Kohler sells lots of parts without that don't have the suffix letter "s" designation.
