Welcome, Stevo64. I hope you enjoy your new tractor, you will find this area of tractorbynet to be a marvelous resource, with many people who actively and willingly help those who need assistance or advice. I certainly have, and do.
As Smoody said, a ROPS system is a good idea, but only part of the equation. Treat it like seatbelts in a car, though. Use it all the time, but operate the tractor in a way that means you don't count on it. It isn't normal for a tractor to flip or roll over, but it is easy for it to do so. Make sure everyone operating it, or in the area it's operating, know how to behave and function safely.
Implements, both using them and attaching them, are safety hazards too, especially with someone "helping" by trying to hook up the implement while someone else drives. What attachments do you have, and what kind of work are you doing? What's the terrain like there? Do you have tractor experience? ( You said your boys don't. ) You will have a lot of fun with your new tractor; they are excellent machines.
