We call them slasher down here I think you lot call them rough cut mowers.
At 6" you have to be really careful about where you put your tootsies, if you want to keep on dancing.
The local shire run some tall walk behinds with a chain curtain at the back and rubber flaps on the non discharge side.
So if you go for bigger wheels condiser some side protection.
Also note when the deck is that high clippings will come out all around the side not just the chute so it is long thick trousers and steel capped boots.
