    I took everyones advise and pitched the front of my deck 1/4"; yep, the cut was better, so were the stripes. My question is why? What is it about the deck pitch that works? I'm using the standard blades that came on the mower. Would it stripe even better if I added high lift blades now? Thanks in advance for any answers.

    What's happening is, the deck when pitched up in the back crates a vacuum that pulls the grass as it's going along. It will also create blow out in the front.

    pitch keeps the blades cutting in the front and keeps the lift pointed in the right direction... a good visual i use for lay-man sake is imagine a helicopter flying... kind of hard to fly forward if your flat or pitched backwards....

    That's a very good example of what blade pitch is doing.

    Does more always = better. In other words, is 1/4" pitch always better than say 1/8" pitch or does it depend on the mower and other factors? thanks

    Too much pitch and you will not utilze all of the blades cutting edge.

    The back. The front should always be lower.

    Also, if you think about it, if the blade is higher in the front, then you are cutting each blade of grass shorter and shorter as you go past it. This causes more work for the blade and motor.
