Kirk has it right. The mag at rest has no advance and is set up at top dead center. Running, it is a flat 35 degree advance at any speed, no variability as in a battery igntion distributor.
There is no scale on the motor to check and set running advance with a light as you might find on a car motor. You don't say what your tractor is. If it has a 113 or 123, it takes some measuring and figuring, but you can make your own marks -- one on the timing cover and two on the crank pulley, one at TDC (for static timing of ignition and valves) and another at 35 BTDC just to check the running igntion timing. If it's an H or M, it already has the first two marks and you only have to determine where the spot for 35 degrees is and mark that.
Only caution I'd offer about moving the mag to advancing your running timing any further than where the mag runs is that it will also advance the static timing. Any advance on a static motor can cause a handcrank to kick back viciously. If you have any plans about using the handcrank, you want to develop some real good discipline about doing that safely, which isn't a bad idea anyway, even when set up at TDC.
Set it up by the book and see how it runs. If there's problems check back.
