At 90 hours on my F2690, I had the first minor issue. I have the 72" rear discharge deck and I noticed one of the front deck gauge wheels wasn't running true. I knew I hadn't hit anything hard enough to damage it and the problem was 3 of the 4 nuts holding the two wheel halves together on the hub were very loose and the fourth was entirely missing.
Fortunately an easy problem to solve, I replaced the missing nut and used Loctite on all four of the bolts. Then I checked the other side and 3 of the four were starting to loosen so all four of those also got the Loctite treatment.
This was likely a supplier issue of not properly tightening the nuts down sufficiently in the first place but the Loctite should prevent future problems. The wheel assemblies themselves are likely a dealer installed part during initial setup but these were the four bolts that capture the two halves of the wheel together with the bearing hub sandwiched in the assembly and would have come assembled from the supplier.
These same style gauge wheels are used on a number of the Kubota front mower decks so if anyone has taken delivery of one in the last few years, it is worth a look. My deck would have been built in late 2022 because that was the delay in getting the F2690 delivered during the pandemic shortage, the dealer brought it out just before Christmas 2022.
Otherwise, I love the operation of the Kubota F2690 and it definitely mows more quickly and cleanly than the 72" midmount deck on my Deere 955 which now gets to keep its loader mounted all of the time since it doesn't do lawn duty.
