</font><font color="blue" class="small">( I really enjoyed my X585, but do recall the blade had reasonably strong down pressure even in the float position. One thing you might consider, assuming you have a hard surface is a rubber squeege kit for the blade, so the rubber is taking the abuse and not allowing the cutting edge to scratch your hard surface. )</font>
The rubber edge works great for moving snow and won't tear the grass up if you happen to go off a little. Anyone with a stone driveway knows how well it works scraping the stones off of the grass and back on the driveway without tearing up the lawn.
There is no down pressure in the float position if working properly. Only the weight of the blade.
