Question edited for clarity. Question moved to John Deere. Are you sure the new belt was the right size? It shouldn't be on maximum tension and still come off. They do have a history of throwing belts. Take a look at the videos. https://www.google.com/search?q=JOHN+DEERE+LA135+Belt+comes+off ..

Question edited for full 'maker name model (what it is)'. Question moved from Cars and Trucks. Wiring schematic in the link. Normally a wire that has rubbed and shorted to the body. https://www.google.com/search?q=john+deere+z445+wiring+diagram ..

There's little in free information available regarding 997 DTC errors other than the handful in the owners manual.The only two temperature sensors I find in the wiring diagram are engine and transmission and only the transmission temperature interrupts the PTO so I believe the "start thermal protection" is a hydrostat pump overheat state and shutting down the PTO is their way to protect the pump.My only suggestion is make sure the hydro pump is clean and clear of debris and service the hydro, new filter and replace fluid.

Its on google just found it just put in john deere 777 mower belt track it shows how it goes once you see it its simple to install , you may find it on u tube . I changed my belt bit of a hair pull but once you see it .Its easy .

Check battery voltage.

It's an older mechanical injector diesel and fuel control so once running it needs no electrical power. The dash lights etc. are easily powered by the alternator. But once you shut if off, a bad battery cell or poor battery connection may effective kill the electrical system.

You need a Service Manual and check for codes. https://www.google.com/search?q=John+Deere+5065e+service+manual Charging problems are a known issue. https://www.google.com/search?q=diagnose+charging+system+on+John+Deere+5065e .. ..

With the mower turned OFF check the blades to see if they aren't bent and if it spins freely. There should be resistance when you hand turn the blades. A bent blade can jam and lock up the drive system. If the blade spins freely and has no resistance check the drive belts from the blade pulley to the gears that run the blades. Hopefully you have just had a drive belt come loose or break, a reasonably cheap and easy fix. If the belts are OK you will need a mower mechanic to look at the gearing for the blades.

Wiring diagram shows fuse F5 20 Amp "Switched Power" feeds rear PTO switch.

check the clutch. sounds like it is out.

Check the resistance of the PTO clutch winding with the PTO power cable disconnected. It should read 2 - 4 ohms.

The engine does not need to be running for PTO to engage but all safeties must be operational.

I believe the red led ON indicates the PTO clutch relay is (should be) energized. So if the red led is off then the PTO relay is not energized hence no power to the clutch. Check all fuses. You need to test your way back from the PTO switch to the PTO relay, through the safeties.
