B1750 HST Problem

[ES1]

Heard a banging noise at the foot peddle location.
Removed bolt on HST peddle and tried to remove but could not.
Removed top cover and saw front wheel drive u-joint disconnected and was the noise problem but now the tractor will not go forward or back 2 or 4 wheel.
The HST will not engage.
Any suggestions?

Thanks

Are you sure it is the front drive shaft that is disconnected? Could it be the propeller shaft going into the HST that is disconnected? That would explain why the tractor does not go forward or reverse in 2 or 4 wheel drive.

The yoke looked like it was coming from the front so I assumed it was for the front wheel drive.
How can I tell if the propeller shaft going into the HST is disconnected?
As you can tell not mechanical at all.
