I wrote Kubota, called Kubota, emailed Kubota and pretty well wore my dealer out on a treadle problem with a 5030HSTC. I finally got satisfaction when I sold it and bought a John Deere. I've written, sent pictures, emailed pictures, called, shown my dealer problems with pathetic welds on the door frames on my Kubota RTV1100. Kubota did exactly nothing. At about 14 months the weld that looked like bird poo broke as I knew it would. Not only were the welds absolutely terrible, but the 1" square tubing used for the door frame was a full 1/4" out of alignment where it was 'welded' together. I took both doors apart, ground off their pathetic weld, lined the frame up properly, welded them properly, repainted them and put them back together; all at my expense. Kubota wouldn't even pay for the paint! That's the way to show me Kubota!
As soon as John Deere comes with a diesel powered Gator that has a factory cab with heat and A/C, I'll likely unload my RTV1100. It's really too bad. Kubota can make quality products. Unfortunately, it looks like they are going to have to go the way of General Motors and Chrysler before they wake up and realize that those of us shelling out our hard earned cash have alternatives. Kubota really has no excuse because their product isn't crap like GM products are (yes, I own 3 of them!) and Chrysler products are. Kubota's problem is that they are complete failures at customer service and at putting any merit in customer satisfaction. Producing a very well made engine that has a great track record is not enough to keep a company ticking. I believe that they are going to have to learn the hard way that a total lack of customer service and the power of the internet can, and will, bring them to their knees. It's really too bad, but I'm not spending any money with a company that is finished with me once my check clears.
