The only difference that I can tell -up close and spec's is the color for the frame and the ability to lock out the PTO in reverse....otherwise they are the same machines....
However I feel one of the best features were removed (why I dont know) was the reverse lights on the 3235. They were last offered as standard on the 2003 models but not on the 2004 or 2005 (GT 3200). But they are the same money, so you pay more money over the 3204 or 3100 for diff. lock, tilt steering, and slightly bigger axels and 2 hp....Not a big difference for the price....IMO they still are a great regardless
