Thats a heck of a machine to throw a kid on and send him miles down the road
I started "driving" at 5 with instructions to keep it in second gear and basically steer a pickup to the other end of a field(about 2 miles) and shut it off when you get to the other end. farming-wise, I started on a 4100 International tractor with a harrow at age 7. I was driving twin screw tandems by age 10 moving hay and grain. Granted, this was in North-Central Montana so it was mostly section line roads, and very little traffic.

99% of the time the bushings in the drag link are loose. 

Large tires and dry air seem to destroy the things.  It's easy to fix.

I got into the 'death wobble' on a Kawasaki 750 triple, it wasn't called a widow maker for nothing. Of course I may have been going waaaay too fast but will plead the fifth. Parked that beast and never rode it again.

Come to think of it I did have that happen once, would have been back in the 80's, and yup - still remember exactly where I was.

In tractors i think it leans toward insufficient caster angle pretty often.  Not adjustable.
Mike is correct on that. Ever watched a shopping cart front wheels wobble when the cart had no load in it? (I refuse to push one that does that and grab another). OCD I guess. Not enough positive caster. Same holds true on the “Ford Death Wobble”.
Much work has been done on this. Not just Ford trucks. I’ve even seen Jeep CJ5’s do this. Positive caster adds stability. Manual steering vehicles back in the day had less positive caster to make steering a little easier. Add power to an old late 60’s manual steering F-250 4x4 and spin the wheel sitting still with your finger. 
Don’t get me wrong, worn components such as tie rod ends and track bar bushings will also contribute to this scary phenomenon.
Be safe,

Brent
