    Mower is leaving a strip of grass(or so it looks) on the non-discharge side of the mower. It is a 36" metro with single blades. I thought at first it was just higher on that side, so I lowered air pressure but that only made it worse. The grass is cutting some, but still leaves lawn 1/2" higher on that side about 1" wide.

    Are blades sharp and the underneath of your deck clean?

    Some "stupid check" reminders...

    When you put the blades back on, did you make sure they were the same height? Just turn them until they are as close as possible, the sharpened edges should be the same height.

    Are they old blades? Sometimes older blades, as they are sharpened, actually are slightly shorter than when new. Especially with 36" mowers, this can be critical.

    Are the blades straight and true? Did an impact with rock/stick/baseball dent them?

    Is the deck straight? Are the front wheels straight?

    Are the blade spindles in good shape, straight, and bolted on correctly (no loose bolts)?

    Hopefully some of these will help.

    This is weird, I also have 36" Metro with gator blades on it and the Metro cuts like champ, very smooth and flat with nice clean stripe and cut.
    You might want to make sure your baldes are same and the spacers on casters and spindles area are all same. Go back and take count on them to make sure.
    the machine has cut very very beautiful and you should be proud of if.

    I'm having the same type of problem with my Exmark Turf Tracer HP 52", except mine is on the discharge side. I sent an e-mail to Exmark, and this is what they said.

    Thanks for taking the time to write in, I apologize for taking so long
    to get back to you.

    A couple things come to mind with the issues that you're seeing.

    First, I'd check the rake of the deck. If you line the blades up so
    they are pointing to the front and back, the front tip should measure
    about 3/16" lower than the rear, and even left to right. If not, your
    deck may not be 'getting enough air'.

    Second, are you using the blades that came standard with the machine,
    or another type of blade. The reason I ask, is this time of year we'll
    hear some of this from people that use a type of blade called the Gator
    Blade. The grass is so lush and thick that this blade just doesn't do
    well this time of year. To a small extent our standard high lift blade
    can have the same effect, and you may need to try our solid airfoil
    blade, especially during a year that's as wet as this one.

    The last thing would be to look at the pulley and make sure it's not
    packed with debris (I wouldn't imagine it would be at 20hrs), or isn't
    damaged which could cause the belt to slip and reduce the blade tip
    speed to that blade.

    With the machine being so new you would probably be best off taking it
    in to your dealer, explaining the situation and having him look it
    over.

    I hope this helps. If not, or if you have any questions, don't
    hesitate to contact us again.

    Thanks,
    Lenny

    Maybe this will help. I am going to try a low lift blade and see if it helps. I tried the double high lift method today, was a little better, but it started raining and was very wet, so hard to tell.
    Good luck. Grizzly

    Sounds like you have the number of spacers between the spindle and blade wrong. Either that, or you put the blade on UPSIDE down.
