Douglass Kansas | Has anyone ever attached a portable grain auger directly to the auger coming out of a grain bin. In doing this the grain coming out of the bin auger would go directly into the portable auger and you would have no hopper of grain to get wet. The bin auger would be powered by the auger in the portable auger. I would have an 8" bin auger and a 10" portable auger that would be long enough to reach a truck. If anyone knows someone that makes this type of set up, let me know. |

Statesville, NC | I haven't done it, but thought about something similar. I thought of using a gearbox on a 30' load out auger with two output shafts, one going up the tube to power the auger, and one going to the intake end with a pto spline on it. Have a small hopper on it that just fits under the incline auger extension on the bin unloader. Connect a pto from the auger gearbox to the shaft on the bin unloader. |

Statesville, NC | I would use a gearbox like this: http://www.surpluscenter.com/Power-Transmission/Gear-Reducers-Gearb...
It looks like it would bolt right on the Westfield 8x31 auger I had.

Between Omaha and Des Moines, 7 miles South of I80 | Why won't a typical "grain bin incline auger" box work? (see photo = red box) I think the bigger deal to get the auger's U-joint "centered", so you aren't either pushing down, on horizontal auger; OR lifting, too much, on horizontal auger; while running.

I'd think that would work but you'd need to use one that the angle is adjustable (I think NECO has one like this) and it wouldn't really be that "portable", at least not by my definition.

MO | I've seen people that have had an auger come out of the bin with enough length to get a truck under it. All one auger like you are talking about, the trouble was not nearly enough auger power. The motors would overheat if the even had enough to run at all very full. You'd be better off putting a electric motor on your portable auger. |

| Dad has one. His is an 8 to an 8. Works well for him, clean you just can't run it full bore or you will break shear bolts. An 8 to a 10 would be better. It takes about 10 minutes to get it set up and bolted in place. Sorry no pics. |

WC Iowa | We've used that same setup for 15 years on a few of our bins. It first started as 8" to 8", then we got a 10" truck auger and a 8 to 10 incline adapter. the truck auger is pto, and one advantage is no hopper and additional elec motor. We have since converted all of our to a 8 to 10 short incline, and then use a hopper. It can be a a pain hooking the auger up to the auger in the bin. Several times we've snapped the end of the truck auger off (it drove the bin auger). Much happier with a hopper. |

Leesburg, Ohio | We used to have some bins with the flex box and u-joint, and one motor at the top of a long inclined truck-loading auger driving the whole thing thru the u-joint in the box. We also had several bins with the flex box and a short incline coming up far enough so a portable auger hopper would fit under them. Still have a couple of those. Can't wait to eliminate them.
Trust me when I say you don't want to go that way. We have tried to eliminate the flex boxes for a reason...they leak, they plug easily, they take a lot of power, and it takes three men and a boy to move them from one bin to another.
A straight-out bin unload auger with it's own motor dumping into a portable truck loading auger with its own motor is reliable, never plugs (unless something blocks the intake in the bin floor) and the portable auger is, in fact, portable.
If your under-floor bin unload auger is too low to get a hopper under it, then you should consider a 25 degree Hutch bin unloader. The incline portion has a 2" larger auger in it than the under-bin portion, so it hos no bottleneck like the flex box to cause plugging issues. The u-joint in them is greasable and fairly reliable. We have them extended on a couple bins to direct feed a leg boot, so I suppose they could be extended enough to get a truck under them, but I would never consider that.

Nevada, Iowa | I use the one pictured on page 9 of this pdf. catalog - http://www.hutchinson-mayrath.com/pdfs/Catalog-Sections/Std%20Bin%2... - it works well for me. I can leave it hooked up without worrying about rain and there isn't much spilled between moves. It takes a knack getting hooked up easily but generally doesn't take long. I use it at more remote sites and it eliminates motors on a 25 degree unload and it's an electric drive truck auger so I don't need a tractor there to load out. Mine is eight to eight and it's bolted on a 32" truck auger. Uses a 7 hp motor to run and can load a semi with dry corn in about 15 min. if everything is working well. Not super fast but good for the situation and circumstances. |

Central, Iowa | The one Dave refers to is the best set up. It has a hanger bearing at the joint to eliminate mis alignment.
Works well for the customers we have set up.

Leesburg, Ohio | You must be talking about loading a straight truck, not a 1000 bu. semi in 15 minutes.? That would be a rate of 4000 bu./hr. Don't think that's possible with an 8" straight auger, certainly not with a u-joint angle box. |

Nevada, Iowa | 15-18 min. would have been more accurate than "about 15" and we usually load 900 - 925. This angle box is little different from just a u-joint. A piece of special flighting wraps around the u-joint. Eliminates most of the bottleneck created by the joint. |

If its properly designed a U joint won't cause any bottleneck.
Most swing away augers have a U joint in the hopper. If there is proper room around it and enough power turning it, the U joint is not the limiting factor in how much grain the auger will move, the flighting is.
3000+ bph isn't a problem with a 8" swing away that has a U joint in the hopper.
