Calibrating & Adjusting Seeding Rate

NOTE: Seeding rates will vary greatly with variations in sizes of seeds, although the seeding rates listed in this manual are based on an average seed size, we recommend that you test and adjust your primary seeder using the procedures listed below to help insure an accurate seeding rate.

IMPORTANT: The bold italic areas on the seed rate charts are settings which may result in inconsistent rates or damage to feed cups.

1.Using the seeding rate charts, beginning on page 21 to determine the seeding rate for the seed you will be planting and make the following adjustments.

c.On the right hand side of your seeder is the drive system. Change the speed change sprocket, if necessary, to the desired drive type, and adjust the drive idler, see Figure 3-3 on page 19.

d.Locate seed rate adjustment handle, Figure 3-4, at the rear of the seeder, and move it to the indicator number obtained from the seeding rate charts. For best results, first move seed rate adjustment handle all the way to the left. Then move the handle to the desired setting, moving from a lower to a higher number.

2.Secure the seed broadcasting handle at the rear of the seeder to the proper setting, Figure 3-2 on page 18.

3.There are many factors which will affect seeding rates: seed treatment, weight of seed, surface condition of seed, and roller wheel slippage. Minor adjustments will probably be needed to compensate for the above factors.

4.The seed rate charts are based on average size seed. This may differ from the seed you are using. Use the seed rate charts as a guide. For lighter than average seed, the setting should be increased. For heavier than average seed, the setting should be decreased.

5.Complete the following procedure to calibrate the rate for your specific seed.

a.Place several pounds of seed over three of the seed cups at the outboard end of the seeder.

b.Raise and support the seeder so the drive roller assembly will rotate.

c.Rotate the drive roller assembly to see that the drive system is working properly and that feed cups are free from foreign matter.

d.Place a container under the three feed cups to gather the seed as it is metered.

e.Rotate the drive roller assembly 25 rotations to get 1000 square feet. To get on acre rotate drive roller assembly until one acre has been tallied on the acremeter or approximately 1071 rotations. Check the three feed cups to make sure each cup has plenty of seed coming into it.

f.Weigh the seed which has been metered. Divide by three. This will give you the ounces/pounds metered by each feed cup. Multiply by the number of cups on your seeder to arrive at the total pounds per 1000 square feet or total pounds per acre that your seeder would meter at the setting. If this figure is different than desired, set your feed cup adjustment handle accordingly.

6.You may want to repeat the calibration procedure if the results of your calibration vary greatly from the suggested settings on the chart.

To determine seed rates for seeds not listed on the charts, compare weight and size to those listed and use a similar setting. Follow steps 5 and 6 to calibrate the seed rate.

Field conditions will affect seeding rates. When seeding check the amount of seed you are using by noting acres or square feet seeded, amount of seed added to seeder, and level of seed in the seed box. If you suspect that you are seeding more or less seed than desired, and you have accurately calibrated the seeder to your seed, you may need to adjust the seeding rate slightly to compensate for field conditions.

This seeder is equipped with a four-position feed cup door on each feed cup. The highest handle position is for small seeds, the second and third positions are for larger seeds. For application with this seeder, you will only need to use the highest position. Make sure all handles are in the same position before seeding. The wide open position will allow complete clean out of the feed cup.

NOTE: DO NOT open the cup to the wide open position with seed in the box unless complete clean out is desired.
