Have a Cub Cadet 3208 with Kohler Command engine with 1250 hrs on it .... runs great until today , when it did something that it has never done in my 20 years of ownership .... I'm doing a land scape job of major proportions , and towing a loaded trailer of dirt over and over again.... fill trailer dump load ...repeat engine is under stressed, as dump area is down hill ....only driving tractor uphill with empty trailer ..... a short while ago engine plumed heavy white smoke ... oil ? ....so much so that it kills engine in middle of steep hill ....kinda scary stuff. If I let it sit for less than a minute .... it will restart , with huge white smoke again , and can get it to top of hill .... where it will burn off all the smoke....which is heavy enough not to be able to see anything in the path of the heavy white cloud of smoke. As I type it runs perfect , with no smoke .... and I quit the job for the day ...but now afraid to use it . Oil is a little over filled but not much , and I have been doing this project for a month now with no problems.... what gives ?
