Awesome! I have the 3520h with the loader controls on the fender. I got the backhoe, dual rear remotes, and 3rd function for a future Anbo grapple.
Had it for 5 weeks and so far I've added a hydraulic top link and built a dolly for the backhoe to store & move it out of the way. I have many more plans like adding rear warning lights, ROPS lights, ammo box, chainsaw scabbard, etc.
Where did you get your ROPS lights and how did you mount it? Where did you install the switch?
