    One other thought, does the tractor have a working tach? Depending on the task at hand, mowing, for instance, if the rpm's drop after a while due to slippage of the throttle, it could be lugging the engine which can cause it to smoke.

    Could be worn out rings: knew of a Mercedes Diesel sedan, high milage with 3 drivers. Grandfather, son & grandson. When driven by grandson there was lots of blue smoke & it used oil. When driven by the son, it smoked a little on acceleration but used no oil. When driven by the grandfather (& original owner), it seldom smoked & made oil! Explanation was fuel leakage past the rings when babied, less leakage when driven normally & no leakage when the 18 y.o. tried to hot rod it. Don't know why the tractor only smokes after getting hot but you could be burning a little oil & replacing it with diesel fuel if this is a high hour tractor. Would be a good idea to change your oil often & sounds like a problem that may get worse over time. Don H

    You could have oil running down the valve guides. It doesn't take much oil to make blue smoke.

    At least in a gasoline engine, blue smoke caused by valve guides will be most evident at startup and should become less as the engine warms up. Still a possibility though.
