sorry it's taken a while to respond. Vacation rocked. First thanks again for all the help and advice guys. Generally it smokes a little white all the time. Maybe bad fuel, H20 in the tank due to infrequent use, ambient temp./humidity, who knows. After asking a few questions on here a while back I decided I wouldn't fix what wasn't broken. Heck it's a diesel. They all smoke at times right. Well, a few weeks back I put the hog on and decided it was time to cut about 7 acres of pasture. I noticed when cutting the white smoke became almost non existant. Clear exhaust. Wow! That was cool. A fuel tank later and a refill of fresh after I was done cutting I took the hog off. I noticed the white smike again. The next day I did some pretty decent grading spreading crush over the back drive to one of the barns I noticed the smoke the whole time grading. I did notice a small drip of fuel from the bottom of the filter bowel. Befor I could address the issue it completely stopped. no more fuel drip. No drip running or stopped, hot or cold. There was never any change in the oil levels, no change in the engine sound or preformance. No temp changes, just the same old that was easy attitude from the tractor wether smoking a little or not.
