NO!
I have a
L3410 HST and it has been a wonderful machine.
There were some teething problems;
1) leaking from the HST filter (dealer picked up, fixed and returned tractor)
2) Same filter leaking...(dealer picked up, found slightly bent filter nipple, replaced and returned tractor)
NOTE: Kubota now has a new rev on the filter that is supposed to be stronger
And that's it so far! Changing fluids is messy, but that's about it.
Hydro transmission has been flawless. Starting in -35F temp takes only a couple more rotations than in summer, but 4x the glow plug time. I have moved several hundred yards of dirt, re-contoured a lot of trails, trimmed down many hundred trees in the 1-2" range all with very little effort or strain.
Worst problem so far has been the R4's are prone to getting greasy in the Wisconsin Clay. I now have a set of chains and I am looking to try them out!
