Dennis, your tractor is not charging. You are simply running off the battery and when it runs down, you are done. The voltage should read somewhere around 14 volts when the motor is running if the charging circuit is working properly.
Someone else who has this tractor model may be able to help you diagnose the problem, but it could be as simple as a loose or dirty connection - certainly no need to be thinking of a new tractor.
