The reason this probably wasn't done was that the B6000 had a reverse rotating PTO shaft compared to what is "normal" for US and EU market machines (counter clockwise vs clockwise for a "normal" PTO shaft).In that case I agree I am SOL. But does not speak well of Kubota that they care so little for about the consequences of design change on old machinery owners. I have a new slogan for Kubota - "Kubota - Not with you for Life"
Kubota made this machine 35 years ago, I dont know what it is classed as in Australia, but in the US it is classed as a Grey Market machine (not officially supported in the US) and if you give a Kubota dealer the model/serial, they are supposed to say that it isn't supported and they cant get/sell you parts for it without getting in trouble with Kubota.Thanks for the links and I do understand all of this but the brand on the side of the machine is 'Kubota'.
Kubota must have known, or should have known, that in an International world you cannot dictate where the machines you manufacture end up. Kubota's Global Revenue last year was $US1.5 Trillion. (Apple eat your heart out) Wiping your hand of this problem, is, in my opinion, not a mature corporate approach to building long term confidence in your company's products. Kubota made this machine and this problem, it would do their reputation no harm to fix it.
