Yes, it is an 1870. Same part though anyway.
Back together, no issues. I have to actually give props to Kubota design. IF you take these apart the correct way, it goes fairly easy. IF start the wrong way, like I did, it becomes a pita. I liked too how almost all the nuts bolts were same size so I didn't have to swap tools constantly.
In the past I have given no thought to hanging onto the steering wheel to mount and unmount. I will be very careful in the future. I almost think this was damaged by me in the past and it only took one more obstacle to finally break it all the way.
