Be very careful about taking those restrictors out.

If this auger only feeds out of one bin you probably wouldn't have any trouble taking the restrictor out because the tube on the anchor bearing limits how much feed can get into the auger.

If this auger can feed off of two bins DO NOT take the restrictor out of the bin that is closest to the building.  You WILL plug the auger, its not if but when.

Go ahead and try it if you don't want to listen to my experience.

Do you have the "shot put" balls in the boots?  If not I'd try that 1st, they seem to help "here".

We've got several single bin augers that don't have any sort of baffle in them and have very very rarely had any problem with them.

The piece of tubing on the anchor bearing that slides inside the flighting acts as a restrictor to limit the amount of feed the auger takes.  As long as you never cut that piece of tubing shorter you should be fine unless your motor is undersized.

When you go to a tandem bin setup the second bin doesn't have an anchor and if you don't have a way to restrict the flow of feed into the flighting I'll promise you it will plug and it doesn't matter how big your motor is it isn't going to turn it.

I've got one plugged right now and I'm hoping it warms up soon because it is a real PITA to unplug a flex auger. Pretty much involves pulling the flighting out to empty it out and then reinstall it, never fun but even less fun when its sub-zero. 

I'm pretty sure my plugged up auger had to do with all of the snow that I got in the bins about 6 or so weeks ago (whenever that blizzard was), haven't needed that feed line since then but I will need it soon.

The tandem system has advantages but it definitely has one huge disadvantage.

As long as you know about it and don't have inexperienced/uneducated people messing with the slides it doesn't cause too much headache but when it does it is a migraine.

The dual auger tandem AP boots that I have have a different baffle in them than the single auger tandem Chore Time bins do.  IMHO the AP baffles work better, more fool proof.

As for the bins, the AP bin seems like its built as thick as a pop can, the CT bins seem to be built better.

I've had thoughts of doing that.  Did it help?  Have you encountered any problems from doing that? 

I'm assuming the bins would need to be lined up nearly perfect to keep from wearing a hole in the pipe between the bins.
