    I've got an old 52" Great Dane that I may use twice each week. It ran fine when I put it away for the winter but when I brought it out to get ready for the spring I noticed a problem. When I engage the blades there is a squeal that is deafening. Pulley? I have no idea. Can any of you suggest what the problem may be? Thanks

    Replace the deck belts and report back, they could be slipping really bad.

    Tighten the belt tensioner!

    I've had to replace the deck belt because of this.....I had the tension as tight as I could get it and now I'm there again and the belts are slipping. It squeels real bad when you engage them......When I get to certain areas the blades almost come to a stop...this is in places with almost no grass...When I hit sandy areas, the belt jumps off sometimes....

    Replacing the belt has not helped.

    A little tip from a small engine repair owner to me start and run your equipment all winter periodically will help prevent all that stuff and keep things free and loose and moving VS sitting and freezing up it works for me

    You need to visually and physically inspect the machine. The noise could be any or all of several things. Without knowing what is happening we are all simply going to be guessing. You can ruin perfecftly good part by guessing what is wrong with your machine.

    It could be:
    Idler Pulley
    Bearing in one of the spindles
    Belt rubbing guide
    Frozen spindle causing belt to ride in non-moving pulley
    Belt rubbing foreign object
