Note that I think that HST and geared both have advantages and disadvantages. Pick the one that best fits your needs.
OK, that said...
I've read comments similar to the one above many times, but I have another view.
There's a LOT more to safely operating a tractor than being able to make it go and stop. My experience has been that a kid's ability to operate a geared transmission is a good litmus test that they are starting to have the mental and physical maturity required to safely operate a tractor. Before that, they might be able to steer an HST tractor around in circles in the front yard like one of these:
... but little beyond that. We may thank them for their "help", but let's not kid ourselves.
Plus, assuming the tractor buyer will keep his tractor for many years, is it best that his children are never given the opportunity to master a geared trans because Daddy chose an HST (with them in mind) when they were eight years old?
I wanted my kids to be able to go check out (and maybe buy) a classic car:
or truck:
... (many of which are manual shift) and not have to ask the seller to take them for a ride because they didn't grow up regularly operating a geared transmission.
The low gearing and the ability to set and hold engine RPM before engaging clutch make tractors the best vehicle to learn the basics of a manual transmission (ideally (but often not possible these days) to be followed up with Dad's manual shift car/truck/jeep).
Teach your kids to do "difficult" things that few can do these days. They'll enjoy (and often benefit from) picking up those unique skills.
