6 volt Negative Ground?

I've had my Cub just over one year now and this is something I have always found quite odd. After bringing the tractor home and running it a month or two, I had to replace the battery. This is when I first noticed the battery was a 6 volt but was wired negative to chassis/ ground. The positive terminal, connected to the long cable, was connected to the starter. I also have a Super A so I was familiar with 6 volt and had never seen or heard of a 6 volt negative ground system. Any input on what might be going on? I installed the new battery the same way and it started and ran just fine, the lights work great and really not too much to complain about. However, the battery does not seem to charge, and drains easily. I find myself charging it every other week from about three months after it was new. Additionally, the tractor seems to start very slow. I guess I am asking what I should do. Should I put in a 12 volt battery? Should I try to flip the cables and try it 6 volt positive ground? I haven't done anything yet because I don't want to burn anything up, and it works, mediocrely, as it is.
 
Keep it six volt for now and reverse your cables to make it positive ground. Re-polarize the charging system and see if it starts charging.

How would I go about doing this?
Take a short jumper wire and touch it to the "Batt" and "Gen" terminals on the voltage regulator. You should see a slight spark. The spark indicates that the process is completed.
 
Alright I flipped the cables so that they are the proper way. Additionally, I re-polarized the generator, and tested it and it is in fact charging. Thanks so much for everyone's help.
