    Does anyone know what the point of this is on the John Deere Standers?

    Called a "Deflector" ? Two under my deck above the blades are falling down every time I remove the blades, while the other one stays in place. I've been hearing a kind of "whirling" sound when I disengage the blades. I've been suspecting spindles. After tinkering with it today with the engine and belt off since I had nothing better to do, there doesn't seem to be no play in the Spindles / Pulleys. I'm wondering if these loose deflectors could have something to do with this sound? Does anyone know what these are even used for? If I had to take a random guess? To protect the spindles? I figure these would be much cheaper to try and fix that noise first at $6.00 a piece, never hurts to start with the cheapest issue.

    To help keep string/wire and crap from getting wound up on the spindle and damaging bearings......

    Gotcha. That's what I was thinking. I've never seen a big "deflector" like these above blades before. Kind of a different design then most of the w/b's and my other stander. So would you say this could cause the whirling noise when shutting off the blades if one of these deflectors wears out? Two of them are completely falling off every time I remove the blades. While the other one stays up.

    They're made to remove when blades are off for cleaning inside, not sure about wearing out? The don't spin or make contact except upper spindle to block debris

    Hmmm. Maybe I am looking at new spindles then. Just figured it would be worth a shot since they are only $6.00 a piece. Since I have the engine and the belt off right now, I tried turning the pulleys and rocking them side to side and can't find much play, with the exception of one has a little play in it. So hopefully if it comes down to the spindles all the noise is coming from that one. I can't move them when I tighten up the blades, but I do have to fight with them when putting the blades back on. I have to manually hold two of them up with one hand, while I start the bolt and impact it up there with the other hand. The third one just stays up there without ever coming off.
