I have been repairing and restoring these great little tractors for over 10 years now, and have amassed quite a bit of information on the repair and maintance of these machines.
When looking at buying any of these machines bare in mind that some are approaching near 25 years old. They can be completly worn out. Some machines have over 5000 hours on them and are still serviceable. The average machine seems to have 1100 to 1500 hours on the hour meter.
The engine is the main concern, making sure that they don't burn oil or overheat. Check the oil. It will be black and should feel slick with very little oder with No burnt smell. They will puff out some black smoke at startup but should run clean at an idle and under an average load. A little more power and some ok black smoke will usually happen. Blue smoke will indicate bad rings and maby hard cold starting. They will have quite a noisy rattely sound but No Knocks or loud rattles. They do run a little rough at a low idle with two cylinders a little worse at idle. Now check out the radiator. It should not be leaking or have rotten fins. Inside should be clean antifreeze. Turn the petcock at the lower left side of the engine and see if any anafreeze comes out. If not this tells me that the engine has not been serveced in a long time with no coolant changes and might overheat in the summer. People will change the oil but not the coolant. I have found many things that can be worn out on these machines.
The things that are very hard to repair is frame problems, as in worn or rusted items. The deck hangers should be check out thourghly. The rods that support the front of the orange deck hangers will be hard to repair if they are rusted or worn out. The front PTO idler pulley piviot rod that comes right out of the front axle frame can give lots of trouble it it has not been greased at least yearly. Give it a wiggle and see how much side play it has. Front PTO shaft through the front axel will have much play and steering will be sloppy. This part can be very expensive to repair if not greased once in a while.
Jack up the front end and see where all of the loose slop is. Front King Pins can be worn out. Bushings will fix this. Steering gear will be usually worn out, so be prepaired to replace the steering gear, steering plate, and steering shaft. Front wheel bearings will wear out but cheap to replace.
Most mower decks will be rusted out and in the need of a bearing replacement. Usually 10 or more bearings if all are replaced. I have salvaged some pretty rusty decks. Some welding and plate replacement. Sand blast, ospho and paint. The other usuall replacement items will be belts, filters, and deck rollars. Make sure that all items are complete, The PTO double U joint to the deck is over $400 from Kubota. The rear deck gauge wheels are over $100 each. I hope this helps the first time buyers. Kubota items are not cheap but Kubota has all of the parts to keep these machines running. ;-)

Saw your post on Gseries tractors. I own a 6200H with 960 hours. Bought it with 900. Serviced all the fluids at 947hr and it runs great. Some scratches on the deck but no rust. Waxed it and buffed out scratcheson the hood and replaced the mascot on the front. Looks like new. Rattles at low idle, sounds like the transmission fan on the drive shaft. Normal? Looking for attachments. Plow, bagger, 3pt, and rear tiller. Bagger more than any. Any suggestions? Also, cheap places to get replacement parts. Let me know.
