No they don't offer it in a semi power shift transmission like they do with the 6 cyl. models like the 1221 or 1523. There are 1523 models on the ground in N/A with the semi power shift transmission option.
If the 1220 came with a more common/popular 16x8 semi power shift trans option I suspect they would have trouble keeping them in stock.
As for the pto its a push button switch. So it would use a solenoid to activate a clutch pack.
