Take a tape measure and make mark on the outside of the belt and measure the outside diameter of the belt . This will tell you how long the belt needs to be. The belt that the unit shows in my book is 66071-61720, which is a 5/8 X 68 inch belt. I will leave this as information only until I hear from you.
The measure of thisbelt is 78.750 inch this is the belt that drives the transmission. Belt is marked bando red - s l l S B - 7 8.
what you have is an industrial belt. It is a B series belt 78 inches long. It is not original Kubota. The Kubota belt shows one to be 5/8x81 and the number for the newer mower serial number is XXXXX but no one has a cross to it, so we don't know its size. You can see if your dealer has the new number and can measure it, or just go to a mower shop or good belt supplier and match up what you have. Sorry I couldn't help more.
66071-51520 is the 81 inch belt.
Your reply is no help at all. I have already done the things you suggest.
