Nothing in my case. Kubota corporate wouldn't admit there was a problem to begin with, so the dealership, although sympathetic, weren't willing to try to repair it without support from Kubota.
The only success I had was adjusting the position control valve to factory specs. It eliminated the jerky performance but introduced other issues that were worse.
A flawed design that the company refused to acknowledge.
The last I heard from a Kubota rep in my district, was that the L3400 has a "standard" 3pt hitch, and if you want a Deluxe 3pt hitch and the characteristics that come with it, they have those for sale too. They are called Grand L's. They have a different 3pt valve. In other words, it is what it is. If you want more then trade up. I did. I traded for a DK35se Kioti. My L3400hst left the place in perfect condition, with pickup truck bed coating applied to the steel floor, I added SSQA which it didn't have when new, and it's nice very jerky hitch which it always had.
