mike I dont know the specifics on these tractor, but I do know the difference, its fairly simple.

a Magneto system uses cound coil to produce the spark. a magnet passes by the coild and produces an electric spark, which is directed to the right cylinder through the distributor. With this method, no battery is needs, especially if it has a hand crank to start it and u dont need lights.

A non magneto system uses a battery to power a coil, or autotransformer. This autotransformer turns the 12v into tens of thousands of volts to create a spark. The dc current is turned into pulsating dc (which is require to allow the autotransformer to work) via the points. The high voltage is then directed to the right plug the same way as the magneto system.

To me there is not much advantage to with system. The magneto system can run with a dead battery, whereas the non magneto cannot.

I would imagine that a typical coil system could produce a much stronger hotter spark, especially with an aftermarket coil and electronics ignition (which replaces the points).
