Keep in mind that oil has improved a lot in the past 35 years since that manual was written. 5W-20 is fine, 10W-30 is fine, I use 15W-40 in my year-round tractors so I don't have to waste so much oil, as each tractor in my fleet gets used less than 8 hours per year. Just don't run a thin multi-weight in the summer...the engine will use it like crazy. For me, the 15W-40 is a nice balance because it isn't consumed very rapidly during the summer, and it doesn't get too thick when the tractor is in the garage in the winter; it rarely gets below 20 degrees in the garage where the winter-use tractors are kept.
Not to mention you may have a really hard time finding SAE10 oil anymore.

Keep the tractor inside a garage if possible. Really cold starts are capable of doing the equivalent of a couple hours of wear on an engine. I usually start mine, back them out of the garage, then let them warm up at 1/4 throttle until the hydro quiets down. 5 minutes or so.
