</font><font color="blue" class="small">( I’ll be buying my first tractor this spring (probably a JD 990) and would like to know :
1.What kind of maintenance do tractor owners perform on their own?
2. What tools should I get ?
3.How do you learn to operate the tractor?—Just read the manual & practice?
4. Can you recommend good publications on operating and maintaining tractors? )</font>
1) Personally, I'd limit my maintenance to oil/filter changes and other fluids, light bulbs and other, relatively minor tasks. I did fill the tires on my first tractor, however. the 790 came w/ filled tires, and I suggest you let you dealer do that task. Fortunately, I've not had any need to do repairs yet, but I do have the workshop manual on CD-ROM, just in case.
2) Set of sockets (12 point and selected 6 points). I use a 3/8ths and 1/2" sets. The 1/2" is used more then the 3/8th's, but I had those before I bought the tractor. That 990 is Japanese, so all the fasteners I've had to work on have been metric. You won't find many English measurement fasteners on that tractor.
You'll need a Torque Wrench with a high enough capacity to torque the wheel bolts. I don't know what that is on the 990, but 150 to 200 foot-pounds (or the equivalent in Newton-Meters) ought to suffice.
Then, standard flat blade and cross tip (Philip's, Reed and Prince) screwdrivers.
I'm sure you'll buy a filter wrench soon, but I wouldn't buy it before you get your tractor. Same refers to most other specialized tools. That 990 is going to be in warranty for a few years. You really cannot do much other then routine (by the manual) maintenance until it goes out of warranty. That will give you a couple years to figure out what you need.
3) Just like getting to Carnegie Hall: Practice, practice, practice!
Just go slow, at first and keep going slow when ever you feel uncomfortable with a job. Most importantly, use COMMON SENSE!!!
4) The manual that comes with the tractor is pretty good, but don't be surprised in you find a couple errors in it. As far as maintenance, I'd suggest you buy the hard copy ($$$!) or CD-ROM from Deere.
