I just added the Kubota remote kit (Valve 1 only) and it was easy.
I only removed the panel in front of the seat (four bolts and the hydro speed knob). I did not remove the wheel or the seat or the tool box and I found access to be very easy. Installation is about an hour +-
I went with the Kubota part and if fit perfect, looks well made, includes EVERYTHING including mounts for the hoses and quick connects for your implement hoses. I have an
L3010.
The kit is well priced and worth every penny. I ordered mine from Carver.
