Best for owners facing similar electrical or hydraulic mysteries on these models.

It blows when the tractor hits a bump, cutting all power to the ECU and display. No bare wires or shorts were found after taking apart the cowling, so the cause remained unresolved.
The cable had detached from its linkage because the cotter pin holding it had rusted away, letting the cable end come loose.
Check for power and clicking at both 12 volt coils, then remove the cap, coil, and spool to see if the spool moves freely to divert fluid.
The backhoe hose was connected to the tank port meant to bypass the three point hitch instead of to the third function port, so no fluid reached it.
