So what are the '"lot of differences"?
Know which they normally put on the 2025R?
I had the 120 loader on the lemony 1025R and have the 130 loader on the gen. 1 2025R. The 130 is a completely "goof proof" loader; whereas, the 120 would occasionally want to take a dump as I was bringing it up. Would have NEVER trusted it to load the pickup from the side. Would risk bashing in the side of the pickup. The 130 is faster (due to better hydaulic pump on the 2025R vs. 4010) than the one that was also goof proof on the 4010.
