LTX 1045. Where can I get a wiring diagram or wiring information?

Brake switch
PTO switch
Seat switch
RCM / reverse switch

Could be any of the above.

Troubleshoot by checking continuity from the M (magneto) pole of the ignition switch to ground. It should be open (no continuity from M pole to ground.

Methodically disconnect switches until M pole to ground shows open. Then test suspected switch.

A DMM or an inexpensive auto circuit lamp tester will do.

Since the LTX1050 has an electric PTO and the LTX 1045 has a manual PTO then I would say no.

remove the top cover from the engine and remove the small wire from the coil if still no spark the coil is bad

that has a 20hp kohler engine the plug is very hard to see if you place enough hours on the engine that it needs a spark plug remove the top cover of the engine that covers the flywheel with that cover off you can see the spark plug wire its over the v shaped valve cover but clean the cooling fins off while the cover is off

it goes to the tin switch where the pedal linkage connects to the rear linkage

go to this site and put your info in and you should find what you need

how does p t o cable go on a ltx 1045 cub cadet

Probably a bent "drag link". See your owner's manual about checking for damage adjusting the steering. For the LTX 1045, it is "Maintenance Section 6", Page 22. If it is bent, repair or replace as mowerman1857 indicated.

You should also lubricate at the two grease fittings (per side) shown on Page 20 -Lubrication - "with a #2 weight Multi-purpose grease". It may have been skipped at the factory or may have been stored at high temperature before you got it, and dried out. (Text in quotes are from the manual)
