Tc18 losing power

[Mowedover]

I have a Tc18 that will start and run perfectly for 15-30 minutes and then will start losing rpm's and power and will barely pull it's own weight. I can let it set for 20-30 minutes and it will start and run fine again. So far I have drained and cleaned fuel tank, new, fuel, new rubber fuel lines, new fuel filter, new air filters, took apart the exhaust system and blew out/cleaned also.

Check your fuel cap, maybe it is creating a vacuum and not letting the fuel out of the tank. Run with the cap loose for awhile and see what happens or run it until it dies and then loosen the cap and see if it'll restart immediately. I would try the first method though.

I know you said new air filters, but is the hose going into the air filter assembly free of any obstructions? What about when you close the hood? When I first bought my TC-24D the operator's manual was stuck up in the hood and was actually pinching the air intake off and causing the tractor to stall.

Thanks for the tips. With the cap off and I kept the hood open just to make sure the air intake hose wasn't getting warm and collapsing it's still losing power. I did notice that when it starts acting up it's white smoking a little. I also tried bleeding the fuel system when it started with no improvement as well.

Most recent fuel fillup was gasoline, not diesel fual.

I am having the same exact problem. I found that cleaning out the fuel filter, replacing fuel filter, bleeding fuel and injectors still did not fix the problem. Yesterday I drained fuel tank, cleaned fuel tank from above with a wire bottle brush, noticed something rattling around inside the tank (I think this is a internal filter - couldn't remove it with pinchers) - in any case, what did you do to get yours back up and running?

I still have the same issues. Soon I will get to looking at it.
