Grain auger hp requirements

crsutton81 · Nov 11, 2022

I have a 6 inch pto grain auger that the lower end met with misfortune awhile back. I want to shorten it up and make a jumper auger with a pan on it that will swing under the tractor trailer hopper bottom to allow us to have the capability to unload into the regular 8 inch pto bin auger that we typically use to fill the bins. I'm guesstimating it will wind up being 8 ft in length. My plan is to power it with an electric motor. How many hp will it take to run it at full capacity ?

i am quite sure a 5 h. p. motor would be lots. i am running a 7 inch 36 ft. with a 16 h.p. one cyl briggs.

man that 6 auger will ruin your cap to unload

(quoted from post at 17:47:34 11/11/22) I have a 6 inch pto grain auger that the lower end met with misfortune awhile back.

1 HP will probably be enough, 1-1/2 for sure.

We ran a 6'' X 28' for years with a 3 HP electric motor.

Lots of variables to consider.

Maybe this will help.

My guess is not to high a power remember you are basically transferring horizontal not raising it vertically. You can easily push a shovel full across the floor of a truck without to much effort but throw that shovel full over the side. Which is going to tire you out if you do each for 2 hours?

I know it will be slower than the 8 inch, but at least we would finally have some way to get the tractor trailer to unload into the bins if needed. The name brand augers like I'm wanting to make are ridiculously priced for no more than there is to them. Normally we use the 2 ton dump trucks. This would be an emergency use situation.

Probably no more than 3. But you'd be happier with your project with an 8 inch auger. A 6 feeding the 8 will be very slow. The 8 will only be partially full, and crack a lot of grain as well.

2 hp would be sufficient. I have a 10 inch about 6 foot with a 2 hp at about a 20 degree incline.

Why not consider hydraulic drive. With a closed center system you can still run the jump auger while slowing down the throttle, so the 8 inch will run full. Other option would be to use a double auger flight with the 6 inch would move more and keep up with the 8 inch better. A belt and set of pulleys on the end under the truck would allow for one drive to run all of it. this would probably require a 2 horse motor for the double and about 1-1/2 horse for the single. We run about 23 foot 8 inch load out auger with 5 horse and works fine. Runs full bore about into a 10 inch to the truck from bin. My brother has a hydraulic set up for running his load out on a couple bins with no power to them. Will keep an 8 inch load out going and run the 8 inch up to truck with PTO. He uses his 2940 for it. I would like to see if one of the open center system tractors would work for that then he could keep the tractor within a mile of the bin when loading out.

Cat guy, I had thought about powering it via tractor hydraulics and a hydraulic motor. The main obstacle is there is no guarantee that a bigger tractor can be made available to power it when moving grain, especially when putting corn in the bins. Normally we use the 1 row Farmalls and my Ole JD 420 for this kind of tasks being they are small enough to fit in these awkward places and can be made available to do the job. It's a good idea that you have though ! All of our grain handling stuff was designed for use 50 years ago when things were at a slower and smaller scale.

crsutton81 · Nov 12, 2022

Thank you to everyone for the replies. This will give me a really good starting point. When we finish up soybean harvest, this is going to be a excellent project to work on in the shop during cold weather spells where we can light the heater and stay warm. The main reasons for using the 6 inch stuff for this project is because I already have all of the materials for it, and grain handling supplies are hard to come by in my area. An 8 inch diameter version would be ideal I know, but something would be better than nothing right now.

The six inch auger will have about half the capacity of the eight inch auger at similar angles. A flatter angle and higher RPM on the smaller angle can help increase its capacity.

If all else fails you can always replace the entire auger with one that fits your needs.

I have a thought for you(if you have enough parts laying around)lay 2, 6 inch augers side by side in one pan. A sheet metal ^ in the center to keep the grain in the auger. Low to the ground,the pan will be about the same width. Just a thought.

That's a good idea.

I like this idea 504. I'll see if I can salvage enough good tubing and flighting to make it a twin 6.
