Unknown medal seed plates

I have a bunch of medal seed plates given to me with my 249 IH corn planter , theres some with one slot are those for pumpkins and can they be used for the 249 or are they for another type of planter, I was also going to purchase seed and was told they dont use seed plates anymore , how do you size seed for the right disc Im lost on this Ill send pics

The plates with the giant center hole are Ford. The ones to the left are IH. The rest are IH filler plates that get matched to some of the thinner IH plates.

Not surprised Johnny's isn't much help. The pro's use plateless or air planters.

You'll need to figure out how big your seed is & use the manual to determine what plate to use. The measurements for the cells in the plates measure in 64ths if I remember right. If you don't size them right, you'll end up with flour.

Put in your biggest round seed plastic plate and plant some on your driveway, look for seeds 6-8 apart. What are you going to do with your crop? Nobody wants anything less than a semi at the elevator here.
 
Round plates and flat plates.

Small seed, medium seed, big seed in flat or round.

A good seed co will have graded seed for you. Certainly most big farmers have gone to a meter or air system that doesnt need fussy seed sizing and some seed co do not grade as closely as they used to.

Put your plate together in the box, drop in 8 seeds, see if they fit in the notch just right, not to big, but not enough room for a second kernel to go along in the same slot. Try the next smallest or bigger plate to adjust just right.

The plastic plates DO NOT FIT HIS PLANTER. They MIGHT fit a Ford, I do not know Ford planters but they will fit a Deere and with the proper adapter AC And that same adapter would be used for to put those plastic plates in the John Deere horse drawn planters plus some of the very early JD tractor planters And would have worked in any of the Deere planters we had since the first horse drawn planter up untill the 494A being newest I had but were used in the 1200 series plate planters as well as the 7000 plate planters. And I have heard some Oliver planters use them as well. And the slots that I see are in the center of the cast steel plates and are just a product of making them, It is the NOTCHes on the outside edge of the plate where the seed goes and the shape and size of that notch is what determins size or shape of seed that can be planted with that plate. The more notches the heavier population the plate will plant. I would like to see a picture of any plate with just a slot for seed in the outside edge as they did not make a plate like that, if you have one it is a modified plate. Give those plastic plate away before you get more confused. If you can possibly get graded corn If it is not graded good that the larges kernels you can find and start by placing the kernels into the notch on outside edge of plate that are called cells and see how they fit and go from there to see what plate they fit the best in. If you get small kernels and try to fit 2 per cell it will crack the kernels and they will not grow. If any Amish to be found ask them where they get their seed because most will still be using plate type planters and probably small seed companys best place to get seed from. Big national companys will not work with small farmers with older equipment.
 
I don't know beans about the metal plates but IF the plastic ones fit a Ford 309 planter and they appear to be there is a number stamped on them. Use google and you'll probably find out what you have and maybe be able to sell them for a fair price. Good Luck with them!
 
The plastic plates are JOhnDeere 'B' series.I have a John Deere #71 planter. That's what it uses. The metal ones with slots are IH. The rings are spacer rings for smaller seeds.I dont see anything in there that resembles a pumpkin plate.Those are common corn plates. IIRC,A pumpkin plate only has a few (8?)cells.Corn plates commonly have either 16 or 24 cells.You can purchace new plates from Lincoln Ag products. Evergreen,CO.BTW,I suggest you order a book for your planter. It will have gearing charts;spaceing/population charts.....Do not risk a good successful crop without a book to guide you.Really,a less than 50 dollar book can mean success,or failure.A good crop depends upon good accurate seed placement
 
As others have said, the stack of metal plates (the ones with the webbing in the center) look to be corn seed plates for IH hoppers. The ones with the open center and 1 slotted hole are filler plates used for thinner style plates typically found for use in watermelons, pumpkin, and sorghum which need a thin plate to singulate the seeds, and not drop 2 or more at a time on IH hoppers. These style plates will work right on into the CIH 900 planter production, as the 2 fingered drive cog mechanism is the same. The plastic plates that I can see in the picture fit another brand of planter,possibly a John Deere. Lincoln Ag and Lustran to my knowledge are still making seed plates for plate type planters. I checked on getting a watermelon plate for my IH 184 planter a couple years ago, and for this they will send you a blank, which you cut/drill out however many holes you desire to get the seed spacing you need. I have found that grain type plates are fairly easy to come by while produce type plates are uncommon atleast for my area. In the previous post of the planter if I remember correctly, the hopper units looked identical to a IH model 184 unit. On those models there is a drive pin under the plate base that can be moved to have a fast or slow gear ratio as part of the spacing. Between that,the seed plate cell count, and the drive sprocket configuration, this dictates the population settings. I hope this helps and good luck.
 
Just growing for feed company I was going to get seed from says they dont classify seed for plates , where can I get classified seed to fit plates , Ive been making hay for 30 yrs and havent planted corn since , I dont want to buy a 20k planter to plant few acres , thanks for advice
 
Thank you all for the advice I will Definatly need a book for this planter , I lent it to someone that planted pumpkins and he adjusted all out of wack thank you again
 
Your manual will have ,at least mine does has three pages of seed plates and height shims .
Also I see your planter has three speed to set up your planter driving the plates under the seed hooper. , very important for set drop time distances laid out in the manual.

The plastic plates looking like a ring are for round corn kernels or beans primarily soybeans. The Cast plates(rusty) are for corn flat seed. Since this seed has gone by the way of lesser sorted for the newer planters. I would look into using a larger plate and slowing down the seeding rate slightly. In an effort to compensate for the difference in the seed. IT might let a few doubles but would not be a terrible deal for sweet corn since it can be put in hills with a few seeds to the hill. Pumpkins might be a bit more of an issue. Beans like green beans for the table could be planted with a larger flat or a medium round plate look at the table shown by another response.

One other tip that I thought of is to ensure the knockout pawl / roller is turned the correct orientation to best match the middle of the cells in the plate selected for use. In the second picture is the locations to place the hopper drive pin to achieve either a 12 to 40 ratio, or 10 to 20 ratio. On my son's IH 251 planter, it plants way more regularly in the 12 to 40 ratio setting on account of this increases the plate speed and makes a more fluid motion. The lack of seed sizing lately has all but parked the plate planters for field use. If given the opportunity, use a large round seed as it will have a more regular spacing. Sorry if the pics posted sideways as my phone is acting up.

Im gonna have to get the book I borrowed out this planter to guy for pumpkins and he played with the planter, do you know what speed is recommended for corn I have 1-2-3 by gear box , thanks for helping me out
 
Ill have to check the drive pin , guy I loaned it too may have played with that , do you know recommended speed and drive pin setting for corn I have a speed gear box lever 1-2-3 and also the drive pin ratio , Ill have to get that book , thanks for advice
 
I don't rember how but I think there are more adjustments than the gear box, Think different chain settings
 
I'm not familiar with the seed drive transmission on a model 249 planter. On my son's model 251 there are numerous options available based on plate cell count. Wish I could help more but this is going to be a model specific situation where the correct operators manual will pay dividends on the correct way to set it up. Most multi row planters will have a seed drive transmission with several combinations of sprockets to use, and in your case the gear ratio under the seed hoppers. If it were me, I'd take the metal corn plates you already have and once you have the corn seed in hand, test fit the kernels into the plate cells to see which plate fits the seed the best. After that is established, count the plate cells and use this info to compare in the charts of the operators manual to finish setting up the rest of the planter based off of the seed spacing that is desired. Sweet corn seed is graded far less IMO these days than field corn, which has gone by the wayside. I have never had a perfect plate to recommend for a sweet corn style seed. It has always been a trial and error deal and sometimes just live with it situation.
