The radiator cap, part number AR28482, is still available from Deere for about $12.75. Looking into the radiator filler tube, the water should be above the core (tubes), but not completely full to allow for expansion. The owner's manual may be a bit more specific. Start out in a slow gear, to get used to the tractor. The engine is a "variable speed diesel", and you can operate it at any speed you feel comfortable with when working, probably from about 1200 RPM's on up to 2100 +, as long as it pulls what's required of it without lugging. Of course, if you are running any PTO powered equipment, you need to run the engine at a speed that gives the PTO output speed required by the implement. And, of course, when pulling a heavy load, it will cool better at high RPM's. Please consider getting an operator's manual for your safety, and the well-being of the tractor! Often, you can find an original on ebay, or call Deere Service Publications direct at 1-800-522-7448,with credit card in hand, and they'll fux you up with a manual for about $30.00. You'll need your serial number, as there are at least 3 versions of the operator's manual. That's a nice choice of a tractor, heavy and stable. About my favorite Deere, besides my "pet beast" 8630, or a 6030!
