If you're asking what I think you're asking, go to tractor Supply where you can get the old Kubota Orange (which I'm sure your 1884 has) or the New Kubota Orange (which to me has more of a red to it).
Do a search on here for Kubota paints. This topic has come up more then once so I'm sure with a search of the site you'll find out more info and probably a part number to take to the dealer. Or even cheaper head to Tractor Supply like Ireops mentioned with a part number and find the paint cheaper there.
