    I assume one of the spindles are bent. Does one of the blades look like it is at an angle.

    sounds like its bent. remove the spindle (nut on top the housing)
    and examine...roll it on a flat surface

    i think i will start with the spindle i will probably have to replace both of them since the dipshit cant rememeber if he hit it in the center or on the left

    Check your spindle housings very closely, I have had a couple go crack and cause that problem with no spindle damage. Easy to replace about 10 mins, parts about $30:rolleyes:

    on a Hustler Z....hit a stump...Spring before last....

    After a Fall/Winter mulching leaves.

    Spinning unbalanced blade all the time.....

    The cause was spindle bearing bad...

    Check this first...

    I seriously doubt you bent that spindle....

    Or cracked a housing....

    check the bearings first....

    you can get replacements almost anywhere,

    I got mine at NAPA....

    be sure to get premium bearings...

    With metal seals,

    not plastic...

    Not Chinese....

    The lower bearings take abuse from spinning unbalanced blades,

    and anytime you strike something with your blade,

    shock gets transmitted directly to the lower bearing.....

    I learned my lesson...

    Got RGB blade grinder

    and Magna Matic balancer...

    First thing to check are the spindle housings and the spindles. Remove the spindle housings and check to see if they are cracked or broken. Remove the spindle shafts from the housings and roll them on a flat surface to see if they are bent.If the spindles check out ok then you have a bent deck. I have straightened a couple of bent decks for a friend. We removed the deck and used a sledge hammer to straighten it. My friend got these reinforcement rings to weld on to the bottom of the decks spindle opening from our Exmark dealer. This was a couple of years ago, so I don't know if the reinforcement rings are still available.
