yes, GT4 of any outer diameter is not gonna give you mtl, maybe if you could find a replacement pole for the deck, if they are available...

Funny thing that most don't know/never noticed...is that the GT4 and GT4 S have the same deck size despite the difference in outer diameter....kinda makes you wonder how they validate charging 250.00 for the same deck for 5 years, lol....though it is damn good!
