It depends on whether it is a 1st Gen or 2nd Gen Kubota. The 1st Gen tractors have a stronger glow plug and stronger hydraulics. The 2nd Gen Kubotas have a smaller glow plug that might get warm, if the timing is right, less hydraulic power. They are slower in the grading area, smaller buckets and the front bucket lift is about half of a 1st Gen Kubota.
Brian, I hope you are enlightened....
