Went to look at the little Kubota last night. Turns out it is a B6000. 2 cylinder diesel, 4x4 with loader. PTO does turn counter clockwise but I don't really care about that as much. I have a Ford 600 with a bush hog for mowing and other implements. Mainly want it for the 4x4 and loader so my daughter can clean out her horse stalls. Doesn't have a very big bucket but it beats the heck out of wheel barrow with a steel wheel. Tractor Data shows 13 horsepower, has a high and low gear transmission and you can put it in and out of 4x4. Seems to run ok. Blows some gray smoke. I am thinking dirty fuel filter or injectors. Has been setting outside ever since he has had it so the paint is faded and the hood has a few dents in it. I believe it is a 1977 model. Does anyone have any experience with these?
