Interesting. In the second picture you can clearly see the plastic block-off panel where i'd expect the factory remote levers to come through. I don't own a 2X20 series tractor, but i would have expected Kubota to have rear remotes like the 26 & 3030 tractors. Why else would they have the same panel for the levers??
Here is a pic of what i would have expected it to look like........
