About the engine, if it has been setting for several years I don't think it would be wise to turn it over without pulling injectors and oiling the cylinders first. I would want to turn the engine by hand before using the starter. It would also be a good idea to verify that the clutch isn't stuck too, there is an inspection plate on the left side to see inside the clutch housing.
What happened to the tractor to allow it to sit without use? That would be my first question.
FWIW, I paid $3500 for mine back in '97 with a bad clutch, sunburned paint and cracked tires. Only 1200+ hours on the machine and very little detectable wear on hitch and drawbar. The prior owner was ill for some time and this tractor simply sat outside in the weather with only occasional use.
i split the tractor and installed a new clutch kit and waterpump kit, rode it to the tire shop and put new tires on it. A few months later I took it apart and reworked it with new battery, steering wheel, new lighting and wiring harness (home made) cleaned and painted everything after taking apart then reassembled. Looked brand new and I was very happy with it. With everything all totaled I have spent about $7000 on it and have used it for 14 years now, I am very satisfied with the cost/use ratio so far.
