I have a Jacobsen 72" Diesel mower that runs great until I try to cut tall grass the mower bogs down and misses and blows black smoke and will shut off if I continue mowing, when I stop the engine starts to clear up and runs good again.

When is the last time you changed:

Air filter
oil and filter
fuel filter

Diesels live, and die, by air and fuel filters.
