    Has any one else had any trouble with Exmark's new style blades coming loose while cutting?

    This has happened twice now on an Exmark Lazer XS and is unique to the new style blades (Or the Lazer XS?) we've never had trouble with any of the others.........

    Any input is appreciated.
    Thanks.

    Are you talking about the 3/4" headed bolts with the red blades (with splined adapters) or the 15/16" with black blades?

    Still get frustrated that they changed something that WAS NOT BROKEN.

    Mowers have been using 5/8" bolts to bolt on blades for .....well for quite a few decades before I was born. Why is it all of a sudden a problem that needs addressing?

    For the same reason that the Lazer Z replacement throttle cable moves in the opposite direction from the original (rabbit is now slow and turtle is now fast)...

    For the same reason that you can buy spindle bearings for Exmark spindles at a Toro dealer but not at the Exmark dealer...

    For the same reason that Exmark changed the Lazer Z spindle shaft diameters requiring the purchase of new pulley's when you have to buy a new spindle because Exmark doesn't sell the bearings (see above)...

    For the same reason that Exmark considers "field testing" to be 2 reps taking the mower home and trying it on their own lawns (do they have Bahia and St. Augustine in Wisconsin?) and then declaring that the mower is ready for use by most people in most places.

    I'm not trying to bash Exmark, I happen to like their products, however every now and then, As TLS has stated, it wasn't broken, so why was it fixed?

    Richard,

    Sure your not talking about DC???

    Most of the things you speak of are to better something....or make it stronger or last longer.

    The new keyed spindle thingy on the new ones (along with other little things like DIESEL POWER..) are what may prevent me from becoming a repeat Exmark customer.

    Yes, I am sure I'm not talking about DC. Apparently Exmark thought the new spindle is better than the old one or does that only apply to the stuff I mentioned?

    dv -
    i have the xs with a "60 deck and have not had the blade loosen but one time sso far, have around 175 hrs on her.
    but before the xs i used the lazer z with a "60 cut deck that had been replaced with the new style cutter housings and every time i hit an ant mound or some other simi soft something the bolt would losen and in some instances come completely off .
    i like the not-so-tight after i hit something as opposed to having to get a piece of pipe to get the bolt loose. ya gotta just watch it after something gets hit.

    There is something to not having to break a bolt head off after hitting something and having the blade tighten up, on the other hand having a blade come loose under any circumstances is not my idea of a good situation.

    I'd rather have to cut a bolt off than have a blade come flying out from under a deck at an inopportune time.

    Thanks for the info, I'm pretty sure it's due to the new design, as it has never happened on any others,and with only 350 hours on it it's lost 2 blades already. Not good.
