1200 not moving
 

I was hauling grass that I had raked up and was dumping it in the back of my property last night when something in the transmission I belive broke.
The drive shaft is still turning and the gears still seam to be turning but it's not moving. It's a good thing that I have a 147 I totally restored and was able to tow it back to my garage.
Im able to push it in any gear it acts like its in neutral
I appreciate the wealth of info the guys on this website gave me on my 147 restore, so I guess it's time to do the same for the 1200
The first question would be should I attempt to tear apart the tranny or look for another one?
This tranny would pop out of reverse some times so I don't know if that has anything to do with it finally quiting.
Thanks for any suggestions.

You probably sheared off a spirol pin on the rear coupler. Check that first, as it's highly unlikely anything in the rearend broke.

I did the same thing on my 1200, turned out the rear coupler had been wobbling for a while on that pin, and it was egged out inside. A new coupler cured it. (I guess the coupler is softer than the input shaft, thankfully!)

I'd also check the rear spirol pins first. Popping out of gear... more than likely a shifter/shift fork issue. I doubt that you broke anything serious in the transaxle.

If it isn't a spirol pin then pull the shift cover and look around in there, shouldn't be a difficult fix.

checked it today
 

Thanks for the advice guys
I checked it today, the rear couple is egged out and the pin is sheared off
Im glad thats all it was
