Seed, Small Seeds and

Fertilizer Rate Charts

The following pages are to assist in the proper setting of seeding and fertilizer rates for the 12-, 15and 20-foot Three-Point drills, models 1200, 1210, 1220, 1500, 1510, 1520, 2000, 2010 and 2020.

The rates indicated in the charts are approximate values. To assure the most accurate seeding rate it is recommended that the drill be calibrated for the desired seed at the time of planting.

Main Seed Box Planting

Calibrating the seeding rate requires four steps:

1.selecting one of four drive types,

2.setting the seed-rate handle,

3.positioning the feed-cup door, and

4.checking the seed rate.

Refer to the seed rate charts beginning on page 4. These charts list the proper drive type and seed-rate- handle settings for various seeds and seeding rates.

The seed rate charts are based on cleaned, untreated seed of average size and test weight. The rates are based on 9.5L x 15 rib implement gauge-wheel tires on the 12and 15-foot drills and 11L x 15 rib implement tires on the 20-foot drills.

Many factors affect seeding rates, including foreign material, seed treatment, seed size, ﬁeld conditions, tire pressure and test weight. Minor adjustments are likely to be needed. Set and check the seeding rate using the procedures beginning on page 12, then adjust the rate as necessary.

Select Drive Type

Refer to Figure 1

The gearbox is designed to give you a variety of drive speeds for different types of seeds and rates. It is a linear shift pattern design with constant mesh gearing and totally sealed to keep the dirt out. No lubrication is required unless service is needed.

Note: If your drill has more than one gearbox, make sure both are shifted to the same drive type.

To set the gearbox move the selector handle 1 until the desired drive type appears in the window 2 on the handle.

Gear Box Ratios

Setting 2 is 2.06 Times Faster Than 1

Setting 3 is 3.08 Times Faster Than 1

Setting 4 is 5.03 Times Faster Than 1

Set Seed Rate Handle

Refer to Figure 2

There are identical seed rate handles for each drill box. Generally, all need to be set identically. You can stop seed ﬂow to one section of the drill by setting a handle to zero (for point-row planting, for example).

The seed rate handle controls the percent engagement of the seed sprocket in each seed cup.

1.Loosen wing nut 1 under handle.

2.Set indicator 2 to just past value from seed rate chart.

3.Tighten wing nut.

Seed Rate Handle

Position Seed Cup Doors

Refer to Figure 3,

which depicts the seed cup door handle in position 3 .

At each seed box seed tube, adjust the seed cup door handle 4 for the seed size.

The handle has three normal operating position detents:

1(top detent) is for the smallest seeds. Use it for wheat and similar small seeds.

2(middle detent) is for larger seeds.

Use it for soybeans and similar larger seeds.

3(bottom detent) is for oversize or fragile seeds. If you experience excessive cracking with setting 2 , use setting 3 .

Note: Handle position 5 is used for cleanout, not planting. If set to this position with seed loaded, it may be difﬁcult to reset it to a normal operating position.

Checking Main Box Seed Rate

Check Seeding Rate

1.Record weight of an empty container large enough to hold seed metered for one acre.

2.Place several pounds of seed over three seed cups on an outside end of drill box. Pull seed tubes off these three openers.

3.Raise drill off the ground. If using a hitch, insert transport lock pins or turn 90˚ hydraulic lock valve, depending on hitch style.

4.Turn drive gauge wheel a few turns to ﬁll cups with seed. Turn wheel until seed drops to the ground from all three cups.

5.Place a container under the three seed tubes to gather seed as it is metered.

6.Turn drive gauge wheel for one acre: 450 rotations on a 12-foot drill,

364 rotations on a 15-foot drill, or

283 rotations on a 20-foot drill.

Check that the three seed cups have plenty of seed coming into them.

7.Weigh the metered seed. Subtract initial weight of the empty container. Divide by three for the amount metered by each seed cup, then multiply by the number of drill openers for the pounds-per- acre seeding rate. If this ﬁgure is different than desired, adjust seed-rate handle and recheck the rate.

Note: If your results vary greatly from the charts, you may want to repeat the calibration procedure.

8.When drilling, note acres drilled, amount of seed added and level of seed in drill box. If you are seeding more or less than desired, adjust seeding rate slightly to compensate for ﬁeld conditions.
