I need to raise the mower deck of my Snapper rear engine rider. It has a single blade with 30-inch cutting width. Currently, when lever is in upper-most position (#6) the blade still scalps portions of my lawn. I have looked through some online manuals but they are a bit confusing. Help please! -mw

Hi,
If you remove the plastic cover on top, you should find that the idler that moves to tension the belt is in a slot and can be loosened and retightened in a position that will place more tension on it.
Peace,
