Hi I have John Deere 4020 HFWD Synchro here in the philippines which my parent bought. its a Diesel 6 cylinders. The tractor serial number at the back of the PTO the number states T213R 262552R , at the side of the engine the number states 6404 DR-01 315167R .
When I tried to look on it especially on the front drive . I found out that the HFWD connection was cut off. we tested the front solenoid thru the 3 terminals and it works since the tester moves . We are planning to rewire it and plan to revive the HFWD to make it 4 x4 if needed however we are challenge where to connect it. WE look up the parts catalogue and we could not find the switches and its location on this part number
