JOHN DEERE 290 PLANTER QUESTION

buck2013 · Dec 12, 2021

I have a question regarding my 290 john deere planter.
I have a video posted on youtube that quickly explains what I am trying to figure out if anyone wouldnt mind watching and letting me know what they can tell me.

But short story is, the book vaguely describes a 6 and 13 point sprocket to use and which one to use when sowing seed. I need to know what sprocket to use so I can properly space my seeds come spring.

I'd greatly appreciate any advice or knowledge about this old piece of equipment. I had it operational, but just need to know about these sprockets.

Please give the video a watch and let me know! Thanks again!

Easy way to find out.Measure the
circumference of drive wheel.Put on the
right plate and a handfull of seed.Turn
wheel one turn.Place hand under seed
drop tube,catch seed.Count seeds caught
and divide by press wheel
circumfrence.You will then know average
spacing between seeds.However,if sweet
corn or a food plot,really not super
critical.

If it's a four row at 30 inches.....put some seed in it and plant about 10 feet on
your laneway or any hard surface that won't cover the seed. From this distance,
measure off a section exactly 4.3 feet long....this length plus the width of four
rows is exactly 1 / 1000 of an acre. Count all the seeds in this area, multiply
that number by 1000 and you will get the number of seeds per acre. If your row
count or width is different, do the math and calculate your area accordingly.

290 is 2 row, 490 is the 4 row and cannot be narrowed down to less than 36 rows. The 290 can go a bit narrower.

To answer your question, you are using the larger 13 tooth sprocket to drive the transmission as it is set up in the video, if you shift the trans. into the fourth position that should turn the plates as fast as it can. It may make some difference in the population with what plates you use for the type of seed. As was said, throw some seed in and run it on the gravel and count and see what you get. I don't know what that loose sprocket on the right is for. I had one my dad bought new many moons ago, it had a hill drop set up and also a check wire set up. Wish I still had it for sweet corn.
