Having had my share of experiences with little Kubota Diesels, and Kubota dealers... Google everything you can wait a day or two for!
Fuel cut off solenoid went out of the mower, Kubota Live Oak, FL dealer wanted $185 for it. Little bitty thing, the size of a golf ball. Told the wife no, tell him I'll get back to him. Wasn't 5 minutes, I found it on E-Bay, came out of Lakeland, FL. Had it in a day and a half; cost me $65. It was a Buy Now or best offer; I offered him $60, and he dropped the price 50 cent. Told him, "You listed it like that; but I'll pay that for it, before you ask what the dealer wants." He had to ask! Could not believe it when I told him. I could not believe it, when I got the part... It was a factory part. Every mark, every decal, was identical to original equipment on the machine.
Live Oak dealer - Filters... I can buy 3 air filters for what they charge me for 1 at the dealer. Oil filters are half the price. Hydraulic filters, less than half price. They aren't even selling Kubota filters, they're selling Wix Filters and charging Kubota prices for them. HELLO!
Gear box on the mower went out. Kubota dealer in Macclenny, FL told my wife, "That part isn't available anymore, just tell him to bring it over, we'll rebuild it for you." I told her, it might not be available from Kubota, but it is available from Kubota dealers elsewhere, and I can buy a complete gearbox NEW, just add oil and bolt it on, cheaper than the parts to rebuild that one. Let alone the labor added! Had it in 3 days. Wasn't cheap, but it was cheaper than rebuilding it, by a DAMN sight!
John Deere is the same way.
