I have owned a Kubota M8540 tractor for two years. From day one the tractor has had a noise in the shuttle shift. I have talked to everyone from the dealer that sold me this horrid machine to the head man in corporate Kubota. This tractor has been in the repair shop 3 times and the problem still exists. I am fed up with the situation after fighting for 2 years for a fair resolution to this problem to no avail. I advise anyone thinking of purchasing a Kubota product to think long and hard before you take the plunge. Kubota is a bad company to do business with and BUYER BEWARE!
