8870 is a great short persons tractor.  If your over 6ft in order to not have your knees way above your hips your head is hitting the top of the cab.  The guy I farm with is shorter and he does great with it at 6ft 2 if I much more than move it from inside of the polebarn to the outside my lower back goes out.  If you are going from a simpler tractor be prepare to get buried in error codes and electro gremlins.  I'm glad he bought it that permantantly removes removes any desire for me to buy one or anything similar.
