This sounds like good advice. On my Toro Z Master I have been lowering the air to find a better ride, even to the extreme of trying it too low..8psi rear and 6 psi front, just to see how soft I could go. I went Back to 10 rear and 12 front. But on a side hill I got a flat rear tire. Not sure if I pinched the tube or what.
On the Ferris I think one should let the suspension do the work it was designed to do.
