With an alternator your tractor is probably 12V. To get a tractor to turn on 6 volts requires heavy battery cables in good clean shape and yours probably aren't. On the distributor side that black thing you are seeing is the coil. To make 12 volts work on what used to be a 6 volt system you either have to add a resistor to get the voltage at the coil down to 6 volts or a coil that has internal resistor. Resistors do go bad.Your lawn mower battery probably doesn't have the cranking amps to really crank the tractor fast. Those small engines really crank with a good 12 volt battery. The knob you are referring to sounds like the light switch. Is it near the amp meter on a rectangular box with a round top? One thing you may find is your tractor has gotten to where it needs a valve job. I've bought 3 tractors over the past few years (A, Cub and just bought a 100 which is mostly a super A with different sheet metal), they had all sat protected but for a long time without running. All 3 didn't have enough compression to get them to run. Not running is bad news on valves from tractors that old. Super A's were late 40's and early 50's so a lot of things like wiring will have seen better days. Good news is you can find just about any part you need for those tractors new and lots of used stuff around too.

Today's Featured Article - The Ferguson System Principal An implement cutting through the soil at a certain depth say eight inches requires a certain force or draft to pull it. Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are
