"Can someone please explain how "negative grounding" works"
Negative Grounding is when the batterys Negative post is attached to frame ground while Positive Grounding is the opposite. The return current for loads like the starter and lights and ignition etc can use the tractors conductive iron frame (often referred to as Ground) so you only have to run one wire to them. The frame sort of acts as the other wire
Many old 6 volt tractors were originally Positive Ground and then when they converted to 12 volts many switched over to Negative Ground. Two cylinder John Deere 6 and 12 volt tractors, however, were all Positive grounded.
"and how do I know if my tractor is negatively grounded or positive"
You can see which battery post, Pos or Neg is frame grounded, however, some got changed over the years.
A typical old tractor generator works at EITHER polarity provided its correctly Polarized. It dont care which battery post + or - is tied to a huge rusty chunk of iron lol
Some Voltage Regulators are labeled for Pos or Neg ground while others may not be.
A typical tractor coil is Polarity sensitive and should be used as labeled + and -. If its Neg ground the - wires to the distributor while if Pos ground its + wires to distributor. It can still produce a spark at either polarity but its more efficient if used correctly as labeled.

It is also very apparent that these folks are getting a lot of very poor and often very dangerous advice fro
