Tractors

I have looked at a Poulan PRO Rider PB301 at Home Depot. I live in Florida and all our grass requires a 5 to 6 inch cut. All the residential mowers I can find cut to 4 or 4 1/2 inch cut. This is too short, taxes the grass, promotes insects, disease, and browning. The Poulan PRO Rider PB301 seems to have the ability to raise the mowing deck to the 6 inch cut height (all others bump up against the mower frame). My question is, with spacers added to the rear threaded height adjustment rods will the front of the mower adjust to that height so the deck and therefore cut will be level.
