Dealer didn't seem concerned at all about me installing my ROPS. Didn't have to sign anything. But then again, I'm not sure the dealer even knew anything about the subsidized ROPS until I bought mine. Neither the dealer nor their rep at Kubota knew I needed an adapter. To top it off, the Kubota website is misleading on price. I went in thinking it was going to be $148 + shipping on the ROPS for my particular tractor model. Well, the $148 was the price of the adapter. I believe it was $165 for the ROPS bar itself. And I think I had about $117 shipping as I recall. Hard to complain because that's still pretty cheap for a ROPS. Unfortunately there were some other screw-ups (not related to the ROPS) at the dealer I wasn't too happy with.
