at 400 hours, that's a lot of usage. So at that kind of hours there comes many, many questions. Was it maintained properly? What kind of maintenance was done? Who did it? Is a failure normal wear, abnormal wear, neglect, abuse, or indeed a defect? The more hours that a unit has on it the more these are questionable items that hold more validity. Think about it this way. Say you're looking at used cars. You find one you want, but it's got 200,000 miles on it. What's that got to do with anything? At 200,000 miles there are a lot more questions than the one up the street that's got 20,000 miles, right?
and that's where the manufacturer's warranty department is. There are a lot of unknowns when they are processing warranty claims. Look at it this way, from their perspective. Some components are not built by Kubota, they are purchased (outsourced). If said component fails within the kubota warranty period, kubota warranty processors have to get paid by the people who make the part(s) which is just about as annoying to deal with as it is for us consumers to have to carry our stuff to the dealer to request warranty repairs. Say an outsourced part fails and kubota is the one administering the warranty on the unit. Kubota warranty processors have to ask (or tell) the manufacturer of the part that the part is defective-and they often have to PROVE the fact, via pictures or what have you, so that they can get paid. If y'all only knew how much money they lose on warranty repairs in a year, you might raise an eyebrow--or maybe not since a lot of folks just don't care, they only see "their" side of things.
