Hi Matt, sorry to drop off the radar, well I feel a bit dumb, I traced the issue with the rear NO Drive, seems like I am getting power to the drive shaft, but it is spinning in the rear axel, so there must be a spline or bevel gear stripped, any idea what the simplest way to get at the gears to see which one is stripped?

Here is the best advise:

Buy a Kubota WSM for F3680 and follow the detailed instructions how to do it.

Mike, have you checked the coupler that connects pinion (A) to the drive shaft? Jacked it up and spun the wheels? Is anything moving?
Yes the coupler that connects to "A" is not stripped, when it is jacked up, I turn the wheels and there is no rotation of "A" , I am wanting to pull "A" out, but not sure if it is as simple as removal of the "C clip" (70) or if I am going to get into a whole mess.... I could go from the Axel side, but I think that might be more risky . I just want to diagnose it, but need to get into the assembly to see it....

The 4wd lever is on your left while sitting on machine. You can see it is the only lever on the far side in picture. The floor pan is easily removed with only a handful of bolts. After removing all pedals and roll bar.

Hi Matt,
Nice view with the floor pan off. Can you tell me where the safety switches are located on the F3680.

Hi Matt,

Red is the PTO and yellow is what plugs into the seat. (I have it jumped here so I could move machine to wash.) There is another on the treadle. But it can't be seen in this picture.
