I was messing around on my dealer's website looking at used machines and saw a 2016 Z950R that they have which is just like mine. One difference is that it has a Thatcher on it. I don't recall this being a JD Option so probably aftermarket. Any ideas what brand it is? I sent an email to my sales guy. This unit is at a different store in the chain but I am sure he will make a quick phone call for me.
You can see the black mounting bracket behind the caster wheels:
