    So we have these tractors that we're using the inverted blowers. Quite a few have the pins with a roll pin, we've had a few roll pins break and I wonder why we're using these. Other than that's what initially came with the blowers.

    So I start searching and see top link pins and hitch pins and step pins and blah, blah, blah.

    Looks like Braber hitch pins are Grade 8. Can't find any details on the other types.

    Anyone see an issue with using the Braber type to connect the blowers? I know the handle isn't going to break like the stupid roll pins and stuff starts falling apart.

    Well roll pins are not roll pins. In tractor pulling we use what’s called a spirl roll pins they look the same at quick glance but are basically multi layers and are rated for loads. We would snap grade 5 and 8 bolts but not spirl roll pins.

    Maybe I didn't explain well enough but they most assuredly are roll pins. The thing on the far end.

    Yes the end pin that runs Thur is a roll pin. Replace it with a spiral roll pin. When I get back to the shop I will that a picture of one

    Fireside is referring to this kind of roll pin but replacing the whole pin with one with handle is ok to.
    See the difference

    Are you using these on the 3pt? Why are they under load or are they being used somewhere else...

    Yes, the roll pin on the end breaks and we lose the pins. I don't believe we've had any issues with the ones with handles.

    So I assume it's a smaller hole that a hog ring wouldn't work? I have seen single roll pins crack and break though by themselves right in half...

    We use these on anything that is not a fast hitch. Providing you are talking about connecting the implement to the 3 point of the tractor

    You might find the pins in the spring when you start mowing.

    Pins like these are so stupid. Companies will do anything to make something a nickel cheaper if the an engineer says it will work.

    What's even more stupid is someone selling them to me with a blower.

    Use those little pins with a ring. Can't remember what they've called, but the ring snaps over. And they seem to stay in place.

    Are they using the roll pins cause one side has no room to do anything? Ive run into that on my kubotas. If you design something that requires a pin make sure you dont have to be an engineer to figure out the way its gotta go in.
    When i use the black ones with the red handles i drill out the hole for a bigger lynch pin. They made the holes so tiny they only fit clevis pins .
