3 things.
1. The free wheeling, although that is manageable with a very small amount  of common sense.
2. Climbing over the hitch.  Yes, I've done it for over 50 years.  Got a few scars on the shins to prove it.
3. Being around the PTO.  This is one of the main reasons we don't use Old Molly (Gramp's 560) around augers very much.  It's just too easy to make a mistake and end up in the PTO shaft.
I'd add a #4, the brakes.  I've been around 460 and 560's since they were new.  It often takes a special touch to brake both wheels evenly and smoothly.  Most of the time one will lock up before the other does much.  Yes, adjustment and repair can fix that ... for a while.
