Looks like your not getting much response to your question. I found the same thing with my Kubota M5400, which is in the same class as your tractor. Most of the Kubota posts on this forum seems to be for the "BX" and "B" series tractors. On occasion you will see a " Grand L" series question. When you get into the older "Special Utility" class of Kubota's M4900, M5400, and M5700 tractor you see very little information here. The newer "Special Utility" class 5040, 6040 and 7040 seem to be generating more posts now.
