I found one on creigs list asking price is $750.00(box only no running gear)It's seems to be in good shape no rust or rot holes in the hopper so If I buy it I will put a good coat of paint inside and out,set it up a couple of feet so I can get 5 gal bucket under the shoot, I need some more feedback on my new Idea. Thanks

If you go this way, you will still need a foundation to set it on. You can pour piers for the gravity box to set on and then adjust with oak cribbing to get it to the height you want. I would not set it on blocks on the concrete I would move it off the concrete, dig the holes for the piers (below frost line) and than pour them up to ground level. So if you would have to move the gravity box out of there you could.
Have the inside of the box sandblasted and then paint it with Industrial two part Epoxy paint. Industrial epoxy paint is very slippery compared to Rustoleum type paints,

We have one gravity box here, painted with epoxy paint, that will flow ear corn out on its own, with out any assist from a rake or shovel. We are hoping to sandblast and paint the other box this summer.
As to the height under the chute, I would make it about a foot higher than a five gallon bucket, Than make a box to set the bucket on. Because the packed snow and ice will build up over and than you won't be able to fill the buckets from the chute.
A piece of rubber roofing over the top would seal out the weather. I have several pieces of rubber roofing that I use as tarps here and have had them for over 15 years.

I would still recommend raising the side opposite the chute ,at least 2-4" to help gravity flow better,we had one on the farm that had too little slope & never unloaded corn without lots of help, just a suggestion,I will not be stopping around to enforce that idea . :)

The insides on a gravity box should be pretty slick unless the slippery paint has worn off I think slip plate is the name brand.

At Tractor Supply it's "EZ Slide". When I used gravity wagons I needed to recoat them every few years. The stuff works well - take it from someone who was once involuntarily discharged down the chute. :lol: If the gravity box has a shallow slope it may work best if the side opposite the door is elevated slightly.

someone used that EZ Slide on the inside so I will redo it, I think the nut will flow without any trouble(the bottom has a real good pitch to it)and once I decide on a color for the outside(I would like to keep the colors but it stands out like a sore thumb) I will sand and paint it. I will have to modify the shoot, add a knife edge to the bottom of the door,and I found a few welds that need to be fixed.
I am putting another row of ties under the frame in the opposite direction to get it up a little higher plus I need more support for it to sit on but for this year I'm just going to leave it there and only put 4 tons in it,I may move it but Its easy to get too right there, I will wait and see where Its permeant home will be but for now I will call that home.
Thanks for all your input :) .Keepaeyeonit :D

The top of the bin is 7"8" from the ground I asked my coal supplier about his trucks and he told me that it will go at least 9' to the bottom of the shoot, If loading it becomes a problem I can cut out a section of the side extension which is 18" high. I did stop and ask again about it since I passed the yard with the box on the trailer. Keepaeyeonit

I think i would cut a smaller hole in the gate (6x6) or similar,get rid of the chute thats there now ,make a smaller chute,you won't need to have the whole bin so high up & still be able to get a bucket under,the existing gate is a lot of gate to close on coal.

WH,I like that idea better. I was thinking on using a plate on the inside to cut the opening down smaller because that one now is almost 24'' wide and like you said that's a lot of coal all at once :o .I may remove the old gate and replace it with a plate and smaller gate, I don't want to modify it too much just in case I have to return it to a working box. I would like to still use the rack and pinion for the gate. The hight is probably as low as I can go(maybe a little lower,I will see),I think It's ok but the lower the better. Keepaeyeonit

That's a good idea on not cutting the gate but making a plate to fit & then using the rack & pinion to operate the small gate,that should work real good ! Nice coal bin idea. Now if you can protect the ground area under the chute from snow/ice you won't lose clearance for your bucket.

I wouldn't worry about the flow rate or changing the gate - there's something to be said for using things as designed. Flow can be metered with the gate if the mechanism works halfway decent. A loose piece of sheet metal can be used as a deflector/funnel to make sure nothing spills.

Hay all just a progress report I set the bin and put the 1500lbs from the ground into the bin and started to paint(the weather is not on my side this weekend) I got next winters load this morning without a single problem which is what I had hoped for

I did change the door with a 8"W x 9"H and added a shoot, so far it works good but I will see when the cold gets back although I sealed it up to keep the water out plus Its oiled.I have 2 new 10'X12' tarps I will put on after I finish with some minor body work, paint and install the pads on all the corners so I don't kill the new tarps(have a temporary one on there now

How many bushels will fit into that gravity wagon? There are 1.2445 cubic feet in a bushel. If its a 200 bushel wagon, it should just about hold 7 tons.

Larry, It's a 250 bushel wagon I figured about 7.78 tons. The whole top extension area is still empty which will hold at least 2.13 tons so that number of 7.78 is real close I was not going to fill it until I see how the pad is going to do but Bob said there is talk of a price reduction so If thats the case I will finish filling it this summer. This load of Mammoth was $246.00/ton delivered and tax.
