| We currently have a John Deere air seeder with 7.5 inch spacing but am getting tired of the poor seed spacing and depth control of the air drill. So I'm looking at soybean planters on 15 inch spacing so I can get a more uniform stand and depth. I figured I could cut back 25% on my seeding rate as well and save on my seed costs. I'm looking at a John Deere 1790 CCS and I was wondering what you all thought about this machine. Or any experience with different makes of soybean planters. Any information would be welcomed. |

NW IL, Mercer County | White planters are very simple. Put a soybean seed disk in the meter, turn the air up and go. Changing to a different crop is as simple as pulling the old disk off and putting a new one on in 30 seconds.
Only issue is there are not a lot of used ones if that is the route you are going.
Nothing complicated about the planter. Set your depth and down pressure, set the air based on seed size, drop it in and go.

SCMI | White 9000 series on 20" spacing. The extra 5" makes it much easier for a good row cleaner to work if you plan to no till. We have only 1 season with the white but would not dream of going back to the 1790 15" we had for 10 seasons prior. I would agree with your population assessments as well, going from 1560 drills to a 1790 allowed a large decrease for our operation. We have hydraulic down-force on this new white and seed at an average of 117k, with intentions to go lower. On farm trials from the last 2 years indicate that the peak ROI on seed for us has been sub 100k. These numbers are for target seeding rates not final stand counts. |

20 Miles West of Indianapolis Indiana | Are you open to individual box planters or needing bulk fill? Are you primarily no till or worked ground?
Are you looking for a bean planter that can plant corn too in a pinch? |

WestCentralMN | You are on the right track to look at stand uniformity/seeding rates. We ran a JD 1790 12/24 for many years. Very solid planter. Good weight if needed for no-till but too heavy in conventional tillage. In a dry year no issues but in a challenging wet year really saw the negative effects from planting in the wheel tracks. In the 15' configuration you shift the 2 point hitch over so you end up with 10 of the 24 row units planting in either planter or tractor wheel tracks. We had too many wet springs and went to a 3620 white. On 60' width we have only 4 rows affected by wheel tracks. |

WestCentralMN | Did you go with Ag Leader or the Delta Force for hydraulic down pressure. Were you pleased with it? Also wondering what maturity soybeans you typically plant. We are looking at more variable rate soybean planting to deal with disease issues and different soil types. |
|
| |
|
SCMI | AgLeader, we have it on both the soybean and corn planter. Very pleased, wouldn't go to the field without it. Choose AgLeader over PP for the accumulator due to our prevalent rock population. Bean maturities max out at 2.7 and we do get into the 1.8 range ahead of wheat. I have been very happy with variable rate seeding beans, it is very nice to still get those 80+ bu draws with less seed and not have to rake them up out of the dirt. |

|
| Have ran both a planter and an air drill, the only thing I think you'll gain with the planter that might show an economical gain is better section control. Stands behind the planter might look prettier but the yield monitor doesn't seem to care. |
|
| |
|
SW MO | I agree on the white, but really like our Kinze edge vac also. |
|
| |
|
NC Kansas | what attachments/upgrades do you have on your drill if any? Keep blades sharp, use a good seed deflector like Needhams bonilla seed tabs and a spiked closing wheel like the Thompson wheel from exapta (especially if planting in corn stalks) If your boot mounting holes are extremely sloppy then they might need repaired..
we drop 120-140k on 10" spacing and wouldn't want to plant them any other way. keeping the seed in the trench (seed tabs and keep fan speed to a minimum) and covering the trench consistently (spiked wheels) are the best bet to more consistent looking stands. Early, drilled beans are never as pretty as 15's or 30's but as others have said, they don't seem to care come harvest.

|
| I have a 6138 white with the 6900 splitter in the classifieds. It's a 19" spacing. Great bean planter for the money. |

Nw ohio | I agree keep your drill your not going to gain enough to justify trading |
|
| |
|
| So does keeping the fan at a lower rpm seem to help with seed spacing and you mentioned the bonilla seed tabs. I've been looking at those . Do they seem to help? |
|
| |
|
| We took a 4710 concord , removed every other shank and put on Dutch narrow fert boots. Now have 20 in spaceings , works great.
No till right into preveous years stubble. In the Northern plains you can buy a nice concord set up very reasonably. Also makes a very good unit for banding fertilizer. |
|
| |
|
NC Kansas | Too much fan speed, sloppy boots and crappy factory seed tabs contribute to seed blown or bounced out of the trench. Then the smooth closing wheels bounce over corn stalks and leave seed exposed too much. Improved seed lock wheels help too but we haven't spent that money yet... we run 3300 rpm on fan pushing 200lbs of wheat and fertilizer but can back off to 2400 rpm for 50lbs of beans. I've only mentioned about half the modifications you can do to these drills but if start there you'll see improvement.
Reduce fan speed is free
Seed tabs are like $4/row
Spiked closing wheels can be $70 to $100/ row
Fixing seed boot slop can be $30+ per row but the labor is what kills you
Seed lock wheels are probably $70/row
Then there are vents to let excess air out so seeds don't bounce out , narrow gauge wheels, exaptas new uniforce system and so on. |

NC Kansas | Love the Bonilla tabs, expata has their ninja seed tabs too. We got a brand new 1890 2 years ago and I took the new factory ones off before we ever started. They don't work bad but wear fast and break off way too fast |

Bon Homme County, South Dakota | I'll bite. We have a John Deere 1795. First year had not the best stand behind the wheel tracks. Last year was the wettest spring I can ever remember. We made some adjustments to the planter and it worked flawlessly.
1) We put Keeton seed firmers on only the 4 rows directly behind the planter and tractor.
2) 2 Dawn Curvetine wheels on the 4 rows directly behind the planter and tractor, and then 1 Curvetine and 1 rubber wheel on the rows behind the wing wheels
3) Depth setting was 2 notches lower on the 4 rows directly behind the planter and tractor
4) Notch number 3 on the 4 rows behind the tractor and planter for the closing wheels. Notch number 2 on everything else
Should note this is conventional till, using a John Deere 2623VT before planting. Also were aiming for 1 1/2 inches deep. You could not tell which 4 rows were behind the tractor. Very very impressed with how the changes. |

Illinois | Agreed.
Is it an option to block every other hole to try for 15s with the drill? I had the best beans this year with an old drill and half the holes plugged. The "hillbilly split row" out yielded the 30s by about 3 bpa. |
|
| |
|
Christian Co. Illinois | Nothing easier or simpler than a Kinze 3600 with brush meters. Very accurate |
|
| |
|
Clarke county, IA | I wouldn't figure on having any seed savings. Plant beans with both planter and drill at same populations, yield results are the same |
|
| |
|
Croswell, Michigan | I have had a lot of bean planters over the years, JD 750, 7000(30" rows), 1780, Kinze 3600 and now a 12/24 JD 1790...I like the 1790 the best.
The 750...same issues you have now
The 7000...too light in heavy ground
The 1780...nice planter but a clumsy ox going down the road and units too close together
The 3600...frame issues, hard to fill and didn't like the way transport wheels ran over planted rows
The 1790...Center fill+++ more room between row units+++narrow road transport+++ |
|
| |
|
| Agree completly |
|
| |
|
custar ohio | Agreed.
I cuss my air seeder every spring versus the 15" DB.
When we harvest in the fall I kind of forget about it because there is no difference in yield. Beans are tolerant of poor depth and spacing controls. |
|
| |
|
NEIN | The other thing we did to our 1790's and now our 1795 is add additional down pressure springs to those four rows. We have air down force but the addition of those old fashioned parallel linkage springs adds just enough additional force to really make them the same as all the other rows . We cant tell the tire track rows anymore. And to the original poster I have had CIH , then White, then Kinze and am now on my fourth Deere. I am all red but the planters, and having used them all, unless dealer service is a problem, the Deere is hands down the overall best. |

Russellville, KY | +1
White planters are easy to operate, easy to maintain, and relatively inexpensive to purchase. |

Driftless SW Wisconsin | undercover - 12/28/2016 11:47 AgLeader, we have it on both the soybean and corn planter. Very pleased, wouldn't go to the field without it. Choose AgLeader over PP for the accumulator due to our prevalent rock population... FWIW the Ag Leader down pressure system has been Dawn units and technology.

SCMI | We did consider the Rfx system but elected to keep everything on a single platform. Either way, thank you for the quality we've come to know and trust from anything branded Dawn. GFX row cleaners and curvetines are a must on any planter we own. Although we may have to jump the AL down-force ship on the next planter for the new pressure transducer style system. |
|

|
Driftless SW Wisconsin | Thank you for the kind words. Quality is what we strive for. Wait until you see what Joe and his crew have coming up next... Jim at Dawn |

SCMI | I've been asking for a roller crimper that mounts to my existing Gfx arms....... |
|

|
| Have a Kinze 3600 16/32 with the hydraulic weight distribution central fill and brush meters only for beans love it simple and reliable! Wish we had the 3660 for the bigger tanks larger bean size can't quite fit 45 units of beans in each tank. |

SW MO | John e.c.MI - 12/28/2016 22:56
The 3600...didn't like the way transport wheels ran over planted rows
Do you have any suggestions on how to combat that? |
|
| |
|
Croswell, Michigan | I guess my solution was to trade planters. |
|
| |
|
Christian Co. Illinois | I always plant the 4 "main" rows that plant in the tractor tire rows and then get run over with planter tires a notch shallower. If ground is really fresh I do the same with the two outer rows on each side. Works great |
|
| |
|
| Db60 47 row hands down,
3 row soybean disc allows for higher speeds when planting white has the 1 row sed disc sucks going faster than 5 miles while we do some 1 mile fields at 7 to 8 mile an hour no problem |

best soybean planter
