Not too bad. I got mine used also. Mine needed new tires so I put radials in the back and aircraft tires up front (2wd) so I don't have any issues with flats. Ride is nice and smooth, sound is quite. AC does a great job of keeping your hands cold on the steering wheel, but doesn't really blow back into the cab as well as it should. Fuel economy is awful for such a tiny fuel tank. Known problems with the fuel line coming off the tank, but mine already had a rubber hose routed around that issue when I got it.
The biggest problem I've had with it was a clutch pedal that got so stiff I had trouble pushing it in far enough to hit the clutch pedal safety switch. Tried everything I could to adjust it and finally went to talk to the dealer about cost of splitting the tractor and fixing it. Luckily I've got an honest dealer. The sales guy asked the lead mechanic, who said he'd seen it before on these models and to start by spraying the cross shaft with penetrating oil. That worked for a short while then went back to a hard pedal. Next he said to remove the cotter pin (knock it up inside the housing) that is hanging down from the section of the housing under the clutch and make sure there is no water in there. He even said drill the hole out if necessary. I didn't have any water in mine, but I used that hole to spray fluid film up inside their blindly aiming for the cross shaft inside the housing. That did the trick and things have been great ever since.
I also added a tool box to mine since it didn't come with one and I wanted a place to keep miscellaneous pins and such.
I've got a 12 volt oil pump I use for big jobs like changing the fluid. For adding some here and there, I use an old 2 gallon plastic gas can. The little plastic nozzle fits in the dipstick hole on this, and many other tractor models and allows you to pour in oil with no spills. Unscrew the nozzle and it's also a lot easier to refill with a 5 gallon bucket when you stick a funnel in there.
