I sold them new. They shipped the tractor in a crate, hanging from it via cables, and the decks were on a separate metal crate; real heavy, about 450 lb (crate and all) IIRC, just the deck. Tractor was around 700lb including the crate, again IIRC. It was printed in Japanese on the shipping tags and I asked one of the engineers and his translator what it all meant. Anyway--- It was common to swap the decks if a customer wanted a G2000 with a 48", so we'd get a G1800 off of the showroom, remove the 48" deck, swap it onto the G2000, send it to customer, and take the 54 or 60 that was supposed to be on the G2000 and put it on the G1800. Same for G1900.
There IS, however a difference!
You will need to match your tractor's steering setup with the deck you're planning to put on it. Really it's only the rear wheel brackets that are different between 2 wheel steering and 4 wheel steering but they're also different between 54" 60" and 48" so you can't swap the brackets from a 2ws 48" to a 54" 2ws or any 4ws. If you try to, the rear tires will hit the deck wheels, etc.
Any RC48, 54, or 60 decks (RC48-G20, RC54-G20, RC60-G20) will fit any of the G1800, 1900 or 2000. Maybe even the G1700 but there weren't many of those, I think we might've sold one early on and then don't remember seeing one afterwards. Come to think of it, they had RC44-G17 decks as I recall (different than RC48-G20). That had to be in/around 1993, a year after I started, when we first took on Kubota stuff; we had JD and Kubota at the time. Deere just loved that....
