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.
