Since you are not getting any help, maybe I should try.
First off your question is not well stated.
Not enough info. You did name the model, 7000
But need row width. Is it 38”?, 36”?, 30”?, some other?
Also what meter? You state ‘Cup A55413 soybean’
So I am assuming the original Deere fluted soybean meter.
Not the best, but you can make it work OK.
I looked for my 7000 owners manual, sure it is here someplace, but no luck.
A OM chart would be great to have.
I do have a finger pickup chart.
The fluted meter meters ‘Pounds’ not ‘Seeds’
And the OM soybean charts are in pounds per acre. Not seeds per acre.
So need to do some figuring.
Lets say planting seed that is 2600 seeds per pound.
If you set the fluted meter for 60 pounds, and the meter plants right on -
You will have 156,000 seeds per acre. 60# X 2600 = 156,000
BUT if you have some 3200 seeds per pound -
60# X 3200 = 192,000 - Pretty thick.
But here is a Monkey Wrench -
The fluted meter tends to over plant in pounds per acre on smaller seed.
And underplant in pounds per acre on larger seed.
The ‘other way round’ would be much better!!
If you have just a fair amount of ability figuring you will be able to get what you want.
For a starting point. You need to set the transmission even.
That is the same size sprocket driving as driven.
On my 7000 12x30 this is 11 and 11, or on later models 22 and 22.
[Early models use a different chain than later ones. Late sprockets have twice the teeth]
In 30” rows even sprockets will plant 26,100 corn
In 36” rows - 21,800 corn
38” rows - 20,600 corn
Will need to do some testing.
A hard surface would be very nice.
Set the depth as shallow as it will go. [Just one row]
Chain up or maybe remove the covering wheels.
Do this so you can count the seeds dropped. That is without digging.
Plant say four or five feet.
There are 17,424’ of row to an acre in 30” rows.
For 36” rows - 14,520’
For 38” rows - 13,756’
In that first four or five foot test. Move in from the ends a bit. Then mark off one foot segments. Use flags or something.
Count the seeds in these 1’ segments.
Come up with an average ‘seeds per foot’
Multiply ‘Seeds per foot’ X the number of feet in a acre.
As, using 30” rows.
Say 11 seeds per foot average X 17,424 = Seeds per acre.
Figures out to 191,664 - Pretty thick.
Just have to do some trial and error until you get close.
Then fill all the planter boxes - Full.
Go out and plant. Some kind of acre count would be super.
Lets say you can find a ten acre area.
Refill the planter - Full. If using bag seed, count the bags.
Number of pounds X seeds per pound = Total seeds
Total seeds divided by acres = Seeds per acre.
The chart below is Finger Pickup for corn. You can use the sprocket combos for the up or down increases. This is a late chart. You may have the older sprockets. That is 11 teeth, not 22, etc.
Note: This chart is right for the 6 and 8 Wide, also 8 and 12 row 30" planters. the 4 wide, 6 x 30 , or the front folds may be different.
