Ok, so the set screw hole was not tapped all the way through and would not allow the screw to even touch the pin, nothing a tap couldn't fix. The other issue is the pin is designed to be used with a bolt passing through, so when it was assemble the bolt hole was in line with the set screw, but the diameter of the hole is larger than the screw and goes right through which would not allow the set screw to bottom. So the proper fix would be to have a small flat spot machined 90 degrees to the hole in the pin where the set screw could bottom onto and not allow the pin to shift side to side. For now I tightened it down onto the surface of the pin and it seems to hold well, but will talk to the dealer about having it machined or replaced with one that is designed for it.
Also please note while getting something new that has issues is a little frustrating, please don't take me too serious if I sound like I am actually upset, I like to joke a lot and sometimes it can come off the wrong way. The dealer was quick to respond and passed along any information they had to help. I'm an hour away from them so it's not like they can send a guy that easy to see what's up. I also know that not everything goes together smoothly all the time, once a couple things are sorted out I'll be golden.
I am back up and running for now, spent an hour spreading some gravel around the driveway where I removed part of the lawn to widen the parking area. It will take some getting used to with this larger bucket, it's not as easy to see around and lifting a full bucket of gravel is barely noticeable, the
B2650 would feel very front heavy with a bucket full of the same stuff. I also have to be a lot more cautious of my surrounding as it's taller, longer, and wider than the
B2650 was, plus if you bump into something with it there's going to be a lot more damage.
Thanks to all of those that posted replies, it is appreciated greatly.
