Hey all,
I was using my 4430 to bale hay a couple days ago, and the tractor suddenly dropped down to ultra low RPMs and rolled black smoke out the muffler. I shut it down immediately, but then tried to restart it. It fired up immediately, but then dropped back to low RPMs and rolled black smoke. So I let it sit while I worked on getting the rest of the hay in. A mechanically inclined friend came over the next day and tried starting it again, same result. Yesterday another friend came over and I asked him to help me pull it back up to the buildings to work on it. The dang tractor fired right up and ran fine!
The only thought anyone has that makes any sense is that the turbo locked up and was acting like an engine brake, but WHY would it suddenly start running fine again??? The new theory floating around is a fin broke off the turbo and locked it up and fell out after awhile. I have a guy coming Tuesday to look at it, I'm seriously confused. I have 80 tons of poultry litter to spread with it after we dry up again. 4.5" of rain last night.
