Blades on a box blade

[Catman8]

Yep, they are the right size. Bummer.

I don't understand how EA is assembling their BB without having this problem? They must just hammer the bolts tight with an impact and call it good.

I'd be curious to know if all of the cutters they have used from this provider have this problem?

I can't even think of anything to offer......

Most production shops use impact guns and if I was using an impact gun, i bet that's exactly what I would of done without knowing, sucking the square into that round hole, so they probably don't even know it's happening.

The link Pat provided has some bolts that are called (Repair head plow bolts) they look like they have a tab on one side to catch from spinning, I think that's what their purpose is. If I was going to use shims to straighten the blades I would not have to worry about the outside bolts, only the inside ones.

Yep I would get a half dozen of the most likely profiles/sizes. One of them will likely solve the problem. Maybe on both blades.

I deal with grader cutters all the time. My pics are of a new pair of cutters installed with bolts that are five years old. They have been used to wear out half a dozen pairs of cutters rotating them a dozen times each. The square shoulder of the bolt never touches the moldboard. That contact would limit the bolt's ability to wedge the cutter tightly to the moldboard and prevent movement.

I posted a note to Travis for some help and input, I'm sure when they get a chance they will chime in and help with this minor service problem

And after you wedge that square shoulder into a round hole and add a year or two worth of rust I bet your going to be using some colorful words when trying to remove those bolts.

Another option would a hex drive cap screw with flat head. This would give full bearing on the bevel and allow full tightening against the mount.

That's another option, it gives you a way to hold the cap in place, what grade of bolts are you suppose to use in a cutter, these bolts have three lines, grade 5. I'm guessing why they don't use those bolts is because the Alan head would get damaged by rocks and dirt and when you tried to remove them you would no longer be able to get an Alan wrench in the hole to hold it from spinning.

Yes, and last Friday, I left messages in 3 different ways(phone, email, TBN PM) for you to give me a call. I haven't received a call.
