Tc18 losing power

Did any of you ever solve this issue? My TC18 is doing the same and I’ve done the same steps as everyone else, fresh fuel, new filter, cleaned air filter ect

I'm new just posted a thread about my tz24 which I think is fairly similar. I'll update when I fix it but mine is almost for sure poor fuel lines. Diesel is hard on rubbers even those made for diesel and they swell/weaken and eventually collapse on their own. I'd start checking for obstructions in the fuel path. Tank, lines. In my case the lines are bad and the tank has debris in it (glue from the filler neck)... Good luck and I'll come update once I put mine back together.

The most likely culprit being the line from tank to filter housing? Or to the injection pump? Or just do it all?

Just finished re-assembling, runs mint. Going to throw the mower on and mow for couple hours tomorrow and will let you know.

I removed my tank, washed it out with soap and boiling water, rinsed, rinsed, rinsed. Dried it to a week or so, replaced all my soft fuel lines with good quality one rated for diesel and all my filters. Cleaned out the front filter housing as well.

Also found my electrical issue that made it so I had to jump start the thing. It was the small diode in the harness that had gone bad. Replaced that and now I can start with the key.

Next project is figuring out the lighting. The PO had ripped off the lights... Only my front headlights work.

Mowed about 2 hours, regular stuff. then did a dozen pass in the ditch/tall grass. No more power issues here. So I suggest you take a look at the same thing. It was a simple process. If you need help PM me or post here. I'm not online too often though.

Got all my lights sorted this morning. Both front headlights, tailights now work. I found the wire for the turn signal/flashers.

Anyone have a wiring diagram for this model I have a bunch of extra bullet connectors by the tailights I'm not sure what they are for. Does this tractor have brake lights?
