Subject: 7000 planter


Okay guys got the new clutch assembly and lock dogs on today. New shaft and pins. Was curious if someone could snap me a pic of just how the engagement bar is tied in. Should be the first pic I post. Also I ordered new chains all around. Was curious as to if my current sprocket selection was indeed correct for corn. My chain is on the larger sprocket at the seed box and don’t worry about the missing nut for the engagement bracket.

Schlegel Farms, Hagerstown Indiana
The engagement rod looks OK, just need to screw the bolt in more to get another lock nut on the bolt. (I think)....the second picture confuses me a little...I'm not sure what is hanging down in that picture. Actually, both pictures are a little confusing but the rod is just loose on the bolt when it's correct. I'm pretty sure it tells how to properly adjust it in the manual, but it's not something that needs adjustment often.

The picture below might help on the engagement rod.

The large sprocket is correct at the seed box.....the little sprocket is to drive insecticide boxes on the rear of the unit.

As for setting the transmission, you need to just check the operators manual for the population you are wanting and set accordingly.

Here is the planting rate decals.

Here is the finger pickup chart

Check out this thread for more discussion on the sprockets.

https://talk.newagtalk.com/forums/thread-view.asp?tid=618288

From that thread:

paul the original - 3/12/2016 06:59 Settings are all the same. Only difference is the number of teeth on the sprockets. If it says use the 22 tooth sprocket, that is for the regular links. The older planters like my 4 row have that double length chain, so I would be counting an 11 tooth sprocket. 11 tooth sprocket = 22 tooth sprocket. 7 tooth sprocket = 14 tooth sprocket. And so forth. Just divide by two on the number of teeth on the sprockets to use the chart. Or if you have an old chart with a newer set of sprockets, you'd have to double the tooth count. My 6 row has the regular chain links, the 4 row had the long links. I'm not sure I'm making this easier, its easy to do, but I'm stumbling on keeping it a simple explanation..... 11 = 22 7 = 14 9 = 18 Etc. Paul

And

Gerald J. - 3/12/2016 13:52 The 2x applies ONLY to the sprocket teeth, NOT the seed rate. In the early planters with 2040 chain (long pitch exactly twice that of 40 chain and 2040 chain fits 40 sprockets perfectly, just not the other way around) the sprockets were 7, 8, 11, 13, and 15 tooth drivers and 7, 9, 11, 13 and 14 driven. Giving ratios of 1:2 through 2.14:1. with 7 driver and 14 driven through 15 driver and 7 driven. The later planters with 40 chains used 14, 16, 22, 26, and 30 drivers with 14, 18, 22, 26, and 28 driven giving the exact same ratios and seeding rates. The chains are the exact lengths and the sprockets the same pitch diameters. I presume 2040 chain was enough cheaper to pay for the more custom made sprockets in 1970. Gerald J.

As far as the sprocket at the seed box if I remember correctly on the 7000 that is how it should be the smaller sprocket was to  chain drive the insecticide boxes behind the seed boxes.

From your picture and the info from the charts I linked you are currently set on 13 driver and 7 driven which is the same as

a 26 driver and 14 driven and in the chart that translates to a 48,600 population in 30" rows.

On my old 7000 planter I remember planting corn in the 26,100 - 30,200 range.

This is the only picture I have of the clutch engaging lever on my standard 7200 taken before I changed out the shaft.

Also you can add a spring to give yourself a spring loaded chain tensioner instead of cranking the double plastic roller shaft so tight.

I am set up on 36” rows but am thinking I want my population around 30,000. What Sprockets do I need to use?

Ok keep these statements in mind. The rates are the same it just depends on the type of chain you have. You have the longer link chain and the decals on your planter show the lower number teeth sprockets.

paul the original - 3/12/2016 06:59 Settings are all the same. Only difference is the number of teeth on the sprockets. If it says use the 22 tooth sprocket, that is for the regular links.

So from this link

https://www.joharrissales.com/assets/Uploads/PDFs/PlantingCharts/FPU-Chart.pdf

We can look at 36" rows and we see 2 populations that are close to your 30,0000 desired rate.  a 31,500 rate and a 29,700 rate.

Follow those across to the sprocket combinations all circled in red.

Now this chart is printed for the newer regular length chain and sprockets.

In this case

29,700 uses the 30 Driver (bottom shaft) and 22 Driven (top shaft) circled in blue

31,500 uses the 26 Driver (bottom shaft) and 18 Driven (top shaft) circled in red.

Since you have the large tooth sprockets and longer link chains. You simply cut these chart numbers in half and use this sticker which is what is on your planter. Notice the sprockets used are in the same location using either chart.

So in this case we have.

29,700 uses the 15 Driver (bottom shaft) and 11 Driven (top shaft) circled in blue

31,500 uses the 13 Driver (bottom shaft) and 9 Driven (top shaft) circled in red.

Very important to keep straight the driver/driven locations clear in your mind when setting. You simply remove or add the rubber spacers on both shafts to get the correct sprockets lined up with the double idlers.

I hope the illustrations make it more clear on how to use the charts and how to set the sprockets.

Yes thank you so much. And I need a manual bad just haven’t found one for a 4 row wide. Also was curious as to what air pressure you guys ran in your tires. The pics and the explanation are very helpful. Thank you all for the help this site has been very helpful and I can’t express my gratitude enough.

Turn your bolt around. Get another nut. Flat bar on bolt shoulder and nut on each side of cam arm.

Also, if on 30" rows, a 1:1 sprocket ratio is approx 26,100 population. You can calculate up or down from that to get you fairly close to desired population if you don't have a manual. (Edit: if it's a plateless finger meter unit. I Don't know anything about a plate type).

In the first picture - yes - you should turn it around in the same arrangement
it is now. Than add a nut and tighten down against the clutch handle. It will be loose
between the two washers on the link.

My first thought was,where did ALL the grease zerks come from on your new clutch asembly? Our original does not have that many,kudos to you. Second thought was,you must be related to my dad thinking that idler in the pic is "OK" LOL!! Third, The !@##$%^& that busted you about the manual probably doesn't own a planter. Good luck with your settings and have a safe planting season.

Old clutch had 3 zerks new one has 4.

I'm pretty sure even my older 7000 had 3 from new.

OMG, I have only been able to find/grease 1 zerk, and I was LITERALLY on my back 2 1/2 hrs. ago lubing the planter! I did find a hole that "should"have a zerk in it. When I get back out to the farm this weekend,I will take a closer look in the manual. Thanks Von.

Maybe you can whine about me too because, I think he needs a manual also.
Let me guess, you think an operator's manual is just a dumb book.
If he would've purchased a manual, he would know how to route the chain.

Got the new chains on and was curious If I mounting my tensioner right. Does anyone else have the same configuration. Also swapped my sprockets around. 9 driven with 13 driver.

Looks good to me.

That double sprocket in the bottom photo, the book says to adjust it so the maxium chain wrap is on the smaller of the two sprockets.
