Morris 9 series air cart gremlin

[TOM4CWB]

Was the same on our seeder...

From manual:

"Air Leaks
It is imperative that no air leaks occur in the air cart tank as even the smallest air leak from the lid will lead to material bridging in the tank thereby causing misses in the field.
Check the following areas for air leaks: - Tank clean-out door
- Metering body assembly seals
- Collector assembly seals
- Tank lid"

"• Check periodically and at the end of each season for air leaks in the following areas:
1.Tank lid seals.
2.Metering body shaft seals.
3.Metering body to tank seals.
4.Collector to metering body seals.
5.Fan to plenum.
6.Plenum to collector.
7.Inspection doors, for leaks and loss of seal memory.
8.Collector door seals.
9.Couplers between air cart and seeding tool. 10. Access doors on divider heads.
Note: Theremustnotbeanyairleaksfromthetank. This air leakage causes air turbulence in the tank which can result in inaccurate metering rates."9 Series ICT Air Cart July 2016

We are reminded continually to insure these hoses are not plugged on our JD tanks... and that they deliver correct pressure. Morris seems not to have put monitoring of positive tank pressure as a priority. This was always the actual issue causing momentary or quarter pass skipping on just some outer sections of our seeding tool.

Cheers

P.S. outer wings have longer distances for air/seed to travel... therefore tend to be the first to have seed not feed into the meter on the tank. Possible more back pressure in these runs... causing seed flow down to be restricted.

Thanks again tom

Not sure how Morris puts the equalization air into the tanks, but if it is at the outside of the meters it might be like Tom said and affecting the outside meters more than the rest. Too much incoming equalization air might suspend the seed on those meters only.

If there are multiple incoming spots for equalization air, perhaps one of the higher locations is plugged.

The Deere 1910 cart I had was always plugging the pressurization hoses with fine dust. Big enough issue that I sold it and switched brands.

Thanks !

Find a good spray bottle from windex or something and mix about 25% dish soap with water and use that in your search. Spray it on all your lids, seams, hoses involved like the other guys say. If you don’t find any leaks that would be causing it, then I would go back to the metering system and make sure there is no wear on the flutes or play on that shaft in the sections affected, or a build up. Switching hoses and if the pattern moves to a new section of the drill would eliminate all possibility of an air kit problem. If the seeds are thick in the pattern spots, I can’t tell in the pics if they are, then it’s definitely a lack of air problem. If the seeds aren’t thick in those spots, then it’s metering half as much and you have to find the reason why.

I assume this isn't a problem you can find right away, by dropping seed above ground perhaps, or do have to wait for the crop to emerge? That would definitely make diagnosing more difficult, if it takes an entire season to know if a fix has helped. Do Morris rollers have segments like Flexicoil? Can they spin on the shaft?

It looks like the seed is getting suspended by air above the metering wheel, is it the same on all of your tanks or just one?

[BreadWinner]

I wonder it the metering shaft seal is missing or leaking.

We had similar problem with our Bourgault, it was the equalization hose that pressurizes the tank would get plugged. Your case being just the outside wings it doesn’t quite fit, but the problem originates at the tank since all hoses and manifolds have been checked. That leaves you with the meter and tank pressurization. I don’t think it’s possible for the metering rolls to slip so my best guess would be tank pressurization.

mostly front , but thats mostly used for the canary/oats that are the problem

yea , you're right , wheels cannot slip

for sure the spots are heavier than they should be , goes heavy, light, nothing , repeat and then lots where theres no problem
