One of my hydro bunton walk behinds has a fixed deck. After cleaning it the other day I noticed that the front end sits down quite farther than the rear. I looked at the frame/deck were it comes togather and you can lower the rear of the deck to match the front by moving the deck bolts down...what will this change? Will it affect the cut by making the deck pitch even instead of what currently has the rear higher than the front? IT would be nice to find something to create more of a vacume in the deck so I hope this does the trick.
