135 diesel stopped running

[bullfrogbill]

1965 Massey 135. Did about 2 hours worth of mowing at 1750 rpm. Tractor ran fine, headed to shade
tree to let engine cool down. Put throttle to idle, tractor shut off. Tried to get it start no go. Changed fuel
filters , made sure gaskets were in housing grooves. Still no run. Tried pulling to start acted like it was
trying to run one cylinder, black smoke. Need help! Thanks!

Hopefully you didn't overheat it. If not, then...

Does it have fuel? Did you run it out of fuel, or was the tank low on fuel when it shut off? Is there air in the fuel lines? Did you try bleeding the fuel lines already? Is the air intake & filter unobstructed?

These motors are dead simple, there's not a lot that can go wrong - Fuel, Compression and Air are the only things needed for the engine to run.

You can quickly check compression by just cranking it with the starter and releasing the starter, or you can hand crank it if you know how to do that. If your engine loses compression suddenly you'll usually know about it because it'll often make horrifying noises on its way out. I think it's unlikely you've lost compression.

Check the linkage to make sure the throttle is opening,maybe stuck in the off position.

How does your air filter look? Any chance it's plugged up from the mowing?

thanks for the replies. Going to have to make the trip to work on it again. Engine didn t overheat and still has compression. The air filter was the first thing I changed,also checked rubber hose to manifold. No mice. Guess I ll start at fuel tank, check the strainer. May be clogged. Couldn t get it to budge last time. I do have some fuel coming out of that line to the lift pump. Maybe not enough. Will give it a close look over. Thanks for all the suggestion. I also drained around 3 gal of fuel out of tank, so it had fuel.
