Hustler Super Z Blade Bolts Breaking

I have 6 brand new 2012 Hustler Super Z's with the 72" rear discharage decks. Last week I had 3 bolts that hold the blades on break, and 1 the week before for a total of 4. Im curious if anyone else who is running a Hustler is having this problem. They are Grade 5 bolts. I have been using Hustler super z's for the past 7 years and have only broken 1 or 2 during that time, and with the new mowers I have already broken 4 this spring. They do have the Kawasaki FX1000 engines, So maybe it is contributed to the added horsepower driving the blades, or a bad batch of bolts. Just curious if anyone else has had this problem.

I second this. The only thing I could think of is if you are breaking them while putting on new blades? If so don't do so with your impact wrench .

I have only seen 1 broken blade bolt in 25 year's. That sound's like a bolt problem.

blade bolts

We mow commercial areas for an Elctric cooperative and Water districts. The sites are sometimes tore up pretty bad when the add or change stuff, but we stay out of the areas if they are that bad. What we hit recently were rocks that must have worked their way up from the freeze and thaw we get in south dakota. We have mowed the same areas for 6 years and knew the areas well. Im kind of thinking it might be because of the increased horsepower behind the blades, so when the blades do hit something the power causes the bolt to break. And maybe its just us hitting stuff this spring. If it continues to happen I will have to do a little more investigating.

bought a new ferris 3100 last year it has a 72" deck and the 37hp kawasaki.
we mow city parks so hitting stuff we are all to famillar with.
we broke probaly 6 factory blade bolts off seems that you would hardly hit something and the bolts would brake.
so i took a sample to the store and replaced them with grade 8 bolts alot better.
but still if you hit somthing hard it will brake the bolt.
last thing when you put your blade bolt in make shure you torque them by hand.

Do you feel that the horse power of the mower had something to do with it, or the bolt itself?

The only way I can see a bolt breaking is forward momentum of the machine and the bolt catching some immovable object. I'd guess that object would have to be squarish so as to not let the bolt slide over top. Usually the blade will catch before the bolt.

What height are you cutting?

This is odd I admit. I've hit a lot of big stuff in the past and it's usually the blade that cops the brunt. Can you get off set blades so that the blade is same or similar level with the bolt? Obviously have to re think cut height but could be worth a shot.

Edit. Na, forget about the off set blade!

i think the hp has somthing to do with it.
before we had the 37 we had some exmarks 26hp liquid cooled and
when you whould hit somthing hard you would bend a blade or break a spindle.
but now with the 37hp it just breaks the stock blade bolts.
like i said since we switched the blade bolts over to grade 8 the only time a bolt broke was when someone hit i man hole cover.
i think grade 5 bolts are to soft.
