There are, and they helped, but didn't fix the issue. My dealer did them since the tractor was less than 1 yr old so I don't know exactly what they are, it's something like a tension spring or similar that can be tightened if memory serves.
In order to diagnose the issue, my dealer lifted the rubber floor and there are two ports near the back in the centre. They put a pressure gauge on them and they read low when the pedal was pressed. That's what they told me they expected to happen before they tested it, I was there when they did the test and that's what they said the result was. Sorry, I don't know what the proper pressure range should be, just that it was low and that indicated a cooked HST. This test was at Kiotis request and had to be done before a new hst was provided. I'm sure a dealer can help you with the pressures if you have a tester.
