Do I need to take some course to become a tractor driver?

How much could I earn as a tractor driver? I’ve been working with my parents on our farm for 3 years now. Farming is getting more and more difficult to maintain for small farmers as time goes on. I’d like to try and get a job outside, to diversify and also secure my future if our family business finally has to be given up.

I would like to find a job as CS rep working from home. I’m a stay at home dad, but now my kids have both started going to day care. I think I have the qualities for it, I’m god with people both face to face and via telephone. My doubt is whether there are specific conditions or qualifications that I need to be eligible for the job.
