Sorry I have been off the net for a while but thought I would reply to the seat question. I dont know the part number for the seat or even if they did change the part number. According to the dealer, they went to the parts room and pulled a seat from stock that the book called for and it was redesigned. My seat looks exactly the same except the angle is different. It is a huge improvement over the old one. My dealer says they are switching them out and sending them back to Kubota for warranty. They doubt that Kubota will do anything about it because the seat is on so many tractors and financial impact would be huge to replace them all. They are a stand-up dealer and want to keep the customer happy. That is why they will get my business over and over again. I just purchased a rake from them the other day and they were not the cheapest supplier but I know they will stand behind what they sell.
