    I have a 152Z with 150 hours on it. When i engage the blade an awful high
    pitch noise occurs it gets louder as i move forward. The high pitch squeal does
    not stop until i turn the blades off. Is it possible my bearing housing is going
    out i have another 152 with over a 1000 hours and haven't replaced any of
    them. any other ideas or confirmation. thanks

    Not familiar with that machine. Does it have sealed bearings for the blades?

    If you take the belt for the blades off. Spin each component and see which one is making the noise.

    When I read " gravely whining" the first thing that came to mind was slap it and tell it to act like a man.

    Careful there. Gravelys are mean enough that they bite back.

    Serious note, Spindle bearings normally roar when they go bad. Whining is more common on the pto clutch or idler pulleys.
