The warranty has been extended to 4 years. My dealer told me when I had problems with my Gr2100. I only had mine for about a year and had it to the dealer 3 times. The third time I requested that Kubota buy the thing back. With a little persistence, they purchased it back and I got a BX2660. I went for a 100% purchase price but we settled at about 85-90%. I was happy with the final outcome. Dealer played a big role in pushing Kubota to make the deal. At a minimum, I would get them to fix it under warranty. The issues with the GR2100 are very well known.
