Hello, I added two new members to my collection in the form of a 149 and 128. This thread will be about getting the 149 in good mechanical condition. From what I know about the tractor from the previous owner it has had a engine replacement at some point with a newer stock k321. I bought the tractor because I was looking for a higher hp hydro wide frame with hydraulic lift and this one fit the bill. Now I had a friend purchase the tractor for me as I was going out of town for thanksgiving and just had a chance to pick it up and dig into this Friday.

So far it is a little tougher than I had anticipated. I ended up having to pull the motor after realizing the rag joint was torn out on the front end of the shaft. I did get the motor to pop over a few times though before pulling it. It is definitely a replacement Kohler but is a k321. The drive shaft is worn badly as well as the engine and transaxle coupler. This is where I am a little confused.

It was my assumption that all wide frames had the same drive shaft motor coupler as the narrow frames with the spiral pin and coupler with the two notches cut in it for the pin to engage with. However, this tractor has a flex disc joint on both ends of the drive shaft with a motor coupler with a hiem ball joint swivel in it. It appears like it could be from a quiet line setup. Is this something that could have been factory on some wide frames or is this a PO modification when the new Kohler was fitted?

I am going to try to reach out to Jeff and have him fabricate a new drive shaft for me if possible. I can find flex disc joints and the cooling fan relatively easily as well. But I still need to track down the correct hydro coupler and motor coupler.
