So, I ended up purchasing a 1998 Craftsman GT (no numbers after the GT). The model number of the machine is 917.273221 . A couple of things to note about this specific machine. It shows 1145 hours on the meter, but the engine is not the original. The GT came with a Kohler CV24 but at some point in it's life it was replaced with a CV22S. The deck has a couple of small rust holes in it and the pulley covers are missing. The deck belts were replaced by the person who sold it to me and it works when the PTO switch is pulled out. The rear tires were tubed, but the fronts are still tubeless. I noticed that there is some dry rot on the front tires so I am guessing that replacements will be needed at some point soon. What I am surprised about is that the front and rear tires are MASSIVE!! I thought that only the DGT6000 had the larger tires, but this GT has the 8 inch from rims and 24x12's in the back. Also, the seat has some cracking which is to be expected for a 24 year old machine. Lastly, there is some rust on the fenders and the gas cap is broken. A little rough, but not too bad considering it's age.
When I got it home today I did a tune up with the Kohler Tune-up Kit. I also plan to do the hydro fluid and filter change. Which by the way, this machine, while still belt driven, does have the Hydro Gear BDU pump and a separate transaxle. Once I have some free time in the coming weeks I will also replace all of the rubber hoses including fuel lines. Long term it would be nice to take the metal panels off and fix any rust and holes and then to repaint it. While this is not necessarily a project or restoration, I can certainly see myself getting deep into making it run perfectly and look nice! Here are some pictures of the machine:
