John Deere (LX280) electrical

[CobyRupert]

Where is a good place to get John Deere lawn tractor service m*nual or w*ring di*grams, in general, and specifically for a LX280 lawn tractor?

PTO stopped turning. Thought “not again”, It’s on its 2nd or 3rd PTO. PTO measured 3 ohm, seems fine; but no voltage at the plug with switch on or off.
Thinking it might be switch, but hard to test without diagram. Don’t want to replace parts by just guessing.

Edit #1. Further testing: Switch seems to work ok. Switch has 3 positions (Off -On -Reverse Bypass). Switch has 2 rows of SPDT (N.O./N.C) contacts that operate with the Off-On positions , and 1 row of SPST contact that closes when switch is pulled to the Reverse Bypass position (the blue jumper wire).

Edit#2: Switch tested good because it is good. Plugged everything back together and now PTO works. ???!!

Maybe just the plug in terminals needed cleaning?

...but about those w*ring di*grams?

Corrosion of electrical connects is a common problem. Don't know if you are storing this unit outside or not, but if you are, the moisture can raise havoc with connectors. So you did the right thing, even if you didn't know you were.

If this happens again, when you have the connector unplugged, put a little electrical grease on the contacts, that will help prevent bad connections.

When it comes to wiring diagrams, I simply go into my Dealership's parts/service department and ask for a copy. They're more than happy to print one off for me.

Alternatively, they might even email a copy of that page to you.
