Don't have any info on the 3pt or loader. I assume you are interested in lift ability? I have an operators manual but it is with my tractor about 30 miles away. I don't remember it giving any 3pt lift rating though.
If you are mechanically inclined and intend to maintain your tractor yourself, I would recommend you get an operators manual, parts manual, and shop manual. The 3 manuals will run a little over $100 if I remember correctly, but will save you that and more if you have to do any repairs. You can get those at your JD dealer or by calling an 800 number and having it mailed to you, which is what I did. Unfortunately I can't find that number. I am sure someone will jump in here with it though.
