I have a JD 1910 air tank, 430 bu cart. The rear 200 bu tank will bridge on runs 1 and 6, the outside runs. It only does this with oats and barley, both treated and untreated.the agitator is set on high. Have changed rollers, no difference. Can't figure out why it happens. Static cling? (Poly tank). The bridging is random and my blockage monitor will not detect it because I still have fert going through the system, resulting in misses. There are hundreds of these tanks out there ,I'm sure someone has had this problem. Any help greatly appreciated.

If your worried about static you can try and wrap a chain around the frame to drag on the ground. First thing to check for though would be air leaks, especially on the lid.

I am having this trouble this year too. The seed is dry so there’s more dust and humidity is low so the dust collects along the sides of the tanks.

Agitator setting doesn’t seem to make a difference as the plugging is caused by dust plugging below the agitators.

Eliminate as much dust as you can. Throw away the leftover pailfull in the hopper at filling time.

Try empty out the tank before refilling every time to flush all the dust out every time.

Make sure your half width disconnects are turned all the way open. Just because the lever is all the way doesn’t mean the outsidesof the shut offs are turned all the way. As they get older they twist a bit and if they aren’t past the seal on the bottom, the seal acts as a lip where dust can get hung up and start plugging things.

If you are double chute, send the starter blend down the nitrogen pipes so that if the oats bridges your blockage monitor will go off.

That’s all I can think of for now. I feel for your situation-been there.

I can’t see a chain helping any-it’s already connected to an air drill that’s dragging in the ground!

I don't think I have an air leak, all 3 gauges are in the green and theres a violent blast of air when u release the lid latch.
Your dust theory may be correct , seems to be alot just under the agitator. I'm wondering if the agitator should be thrown in the bush with all the other ideas that worked on a computer screen. If you watch the agitator work , it basically blocks off about 60% of the throat going down to the meters. And the wiggling action of the agitator may actually pack dusty material against the edges?
I'm running single shoot but every 30 min or so i shut off fert for a pass and watch the blockage monitor. The turn the seed off and go over the same area with fert. Earlier in the day, I realized run 6 was blocked constantly so I closed half width and was patching in misses with runs 123 open. Thats when i realized run 1 would bridge for 5-45 seconds at random and clear itself. So i can't just stop,jump out and crank handle and to see if its ok. Have to watch it for a while,while it's working.
I've given up on the rear tank for now. I'm using the middle tank and it's been good. I have to stop and fill every hour, but thats better than dealing with misses. I have only had this problem with the rear tank, was wondering if the shape of it had something to do with this problem.
Thanks for the responses

Maver , Stockton is right about the disconnect handles. Sounds like their is a good chance your plastic gates in your meter housings has twisted resulting in the outside runs being blocked. I replaced all my meter housings with stainless steel. I WAS HORIFIED when I took my old john deere original meter housing off and found twisted gates. Honestly I don't know how it seeded the last year before I fixed the problem. I threw the old run out .I couldn't believe the deere engineers could be so stupid using plastic and other corrosive metals. I bought the romfa meter housings out of Arborg MB and I have been very happy. I can use my pinky finger to move the double shoot slide gates and disconnect handles, and clean out is so easy now.. No more hammers. Also check if your agitators are still locked on the shaft. When I rebuilt mine I found some plastic agitators were broken and not moving along with the rest of the agitators. IF you need any other advice on the deere cart I would be happy to help you. I rebuilt mine top to bottom with stainless. From my experience nothing compares to the accuracy of a deere cart. They do have there cons but I have also run Bourgault and they have troubles too.

I third checking the half meter shutoff gates.... we have a 1910 and when we started the season we had to physically get in there and make sure they were opened from the inside.... ours are Stickey and were twisted.... they will stay open until were done, we have accepted that we cant touch them because they wont open properly again if we do..... ours is due for the stainless upgrade....

we had that issue with the same tanks....make sure you are only sedign out of 1 tank at a time to keep th erate up. we were split from 2 tanks so the rate was like 60-40 between the tanks.


Seed from 1 tank, agitaotr on high, stop and pull the roller out often and clean it out. dont foget to open the shut off gates each time

Its a common problem especially with oats. We just cant seed our oats varieties with our 1910. And when I posted a question in my local cropping page most had the same problem. Of course the dealers will say your the only one!!!
Those that had success said the secret was to put through a Geraldton plumbing cleaner which is basically a large fan with the grain falling through the air blast and you have a movable cutoff plate to separate the light dust and heavier oats. Once you have them as dust free as possible chuck in handfuls of Talcum powder in the auger as you fill the tank. That is the only reliable way to seed our varieties. Yours may be different.
I'm currently have trouble with fungicide treated compound fertilizer. Keeps breaking the bolt on the agitator crank then the runs block.
Your probably asking why not get rid of it and buy another tank. Answer is I cant afford to park it in the bush and shell out the cash for another as they have zero trade in value with such a bad name around here.

If the tanks are double shoot, do you have the seed going through the top set of tubes or bottom? If it’s the bottom, there can be a problem with the grain getting around the top tube. Doing large chickpeas years ago, we had to switch our hoses and put them out the top set of tubes.

Whenever we had issues with bridging in our 1910, we resorted to unloading the tank and refilling it. Pulled the meters and cleaned up while making sure things were working properly. Dustier oats that we’re poorly cleaned is the most troublesome or long distance transport can cause it. I would also avoid running out of only 1 tank at full rate and instead split the rate between the tanks.

We also used to have the problem with the bridging and little skips and misses in our fields as the outside runs would not flow properly for the first 200 feet of every pass. I am not sure if it was another post on this forum a few years ago that solved it or if it was Terry D at Cervus Saskatoon who found the solution.
We needed to get more positive pressure in our tanks when working with oats and barley. We removed the pressurization hoses off those annoying manifolds by the tank meters and plumbed both sides directly into the side of the tanks. Run the hoses inside the tanks to just under the lids. When operating with oats barley and wheat we open the ball valves that control air from both top and bottom air streams so more air flows into the tank. We have not had a bridging problem since modifying the cart.
Also those annoying manifolds at the bottom that you are supposed to pull off and clean out every 50 hours we now just clean out at the end of the year. I don’t even know if we actually need to do that at all because they are capped off and not being used.

Having the same issues as well this year on the back tank. Various towers would just kinda phase out and back in over 200m stretches. Happened in Ore42 oats and happening with Sulphur based fert blend. The oats I’m the same with agitation on high, lid pressured, etc. However with the fert is has mainly been dusting off and bridging under the meters. I slide my top/bottom run selectors and it seems to loosen it. Been after the fert dealer to oil the fert more it’s so dusty but maybe it’s making the problem worse? As for the oats the manual says the lightest product should never go closest to the fan, I’m thinking could be a pressure differential bridging the oats in the run that has the least pressure until it breaks the bridge. In the end I don’t think I’ve solved the issue yet.

We have had this issue bad with certain barley varieties and I have always figured that it was not enough air presureizing the tank,just didn't know the correct way to fix it. Glad u posted this and will do the same on our drill.We always put seed in the front tank and out the top shoot,and the air preasure guage for front tank is never in the right position unless all the air is directed to the top shoot. Is there something online where this fix is explained even better with more pics?

Maver, IF YOUR 1910 is a double shoot also check your air flow control dampner . When I rebuilt my unit with stainless I also notice the screw handle was partial seized and didn't turn up or down on the thread properly. So what was happening I didn't get proper air flow between the the top and bottom pipes. Trouble is you cant see what is happening unless you take it a part. Also I am curious what bushel weight of oats you are seeding. I seed 48 lb oats and drop it from the back tank down the top pipes with no problem after the rebuild.

My cart is single shoot. I'm seeding barley, the oats was last year . The barley is heavy, kinda dusty, and treated.

My half width handles do require a hammer, and they are slightly twisted inside. The outside runs that bridged were probably 90-95% open. Not sure if that is enough to cause bridging. Stainless meter boxes for next year. Can't believe jd doesn't use stainless!
My presurization hose goes into the side of my tank and up the ladder to the top of the tank where it is open, like in granite smashers pics. No valve though. Cobra1970 do you have 2 air lines going to each tank? (The factor installed and the one that you put in)
