If you drive one, then drive scag, exmark, toro commercial, and a cub tank, youll notice alot more boune on the dixie chopper, not to mention a way higher center of gravity wich makes their hill side stability way less. Then if you can set the mowers together youll notice the deck isnt that on the chopper as it is on other mowers stated above, youll also notice the frame is smaller/weaker, not to mention they utilize most the time a generac engine, generac is nealy non existant in the commercial machiene, no way comprable to a kawasaki. Their mufflers are not baffled much/high levels of noise. You noted groung speed, its ridiculous and unusable in the real world, their blade tip speed is unsafe in my opinion,
