I don't know what you mean by the back of the tractor, my levers were on either side of the seat. The PTO speed select (540-N-1000) was on the left, the PTO engage/disengage lever (ENG/DIE) was on the right. Depending upon the year of manufacture, that ENG/DIE may be optional. I had one Jinma with it, the other without. The Diff Lock lever is to the right and down, close to the floorboard.
The left (PTO speed select) lever will not work at all, till the right (PTO engage/disengage) lever is in the ENG position. Those tractors configured without that right lever are configured internally in a full time ENG mode, leaving all PTO control up to the left lever.
Take a second look at your levers and controls, and see if any of this helps get the PTO shaft spinning. We can resume from there if that still leaves you with a problem.
