Anybody have any info on the latest status of Kubota derived Zen-Noh tractors? Are there likely to be parts available for these units? Have things clamped down such that Kubota dealers flat refuse to sell parts to corresponding Zennoh tractor owners? Is purchase of a Zennoh tantamount to throwning one's money away? Is a Yanmar made Zennoh more safe and secure as far as parts availability now?
