Important Safety Information

Great Plains Mfg., Inc.

Look for Safety Symbol

The SAFETY ALERT SYMBOL indicates there is a potential hazard to personal safety involved and extra safety precaution must be taken. When you see this symbol, be alert and carefully read the message that follows it. In addition to design and conﬁguration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.

Be Aware of Signal Words

The word that designates a degree or level of hazard seriousness. The signal words are:

DANGER!

Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. This signal word is limited to the most extreme situations, typically for machine components that, for functional purposes, cannot be guarded.

WARNING!

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury, and includes hazards that are exposed when guards are removed. It may also be used to alert against unsafe practices.

CAUTION!

Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.

Section 1 Planter Preparation and Setup

Great Plains Mfg., Inc.

Leveling the Planter

During initial setup and periodically throughout the planting season, check that the planting units are running level. When planting, the top of the hopper support panel (1) should be parallel to the ground as shown in

To level the planter, the bottom of the main frame tube must run between 20 and 22 inches above ground when lowered into planting position. See

Figure 1-4.

To obtain the correct height, reposition the planter hitch on the tongue. Proper tongue adjustment improves seed placement by allowing the row units to operate parallel to the ground.

The mounting holes in the hitch have been offset so the

Top of Hopper Support Level with Ground

6. After wings are off the ground, lower planter. This will retract the wing gauge wheels. The cylinder locks will keep planter from lowering to the ground.

IMPORTANT: It is important that the wing gauge wheels are retracted before continuing to fold the planter. Failure to retract wheels will lead to hopper damage.

7. Continue folding until wings are positioned above the planter main frame.

Unfolding

DANGER!

Keep others away during unfolding operations. Do not walk under wings when unfolding planter. See Figure 2-6 on page 14 before attempting to unfold planter.

Unfolding is best achieved on level ground with the tractor transmission in neutral. Be aware of the clearance re quired to unfold the planter.

DANGER!

Keep clear of overhead power lines when unfolding planter and/or markers.

5. When wing gauge wheels contact the ground, pull planter ahead a few feet while continuing to lower. This will level wings.

6. Remove the cylinder locks by removing the bent pins and pivoting the locks off the cylinders. Replace the bent pin to keep the locks off the cylinder.

7. Position arm wing lock pins as shown, see Figure 2-4. If wings are not level, it may be necessary to pull forward a few feet to lock wing lock pins.

NOTE: If unfolding planter with hoppers fully loaded, you will need a tractor with at least 1900 psi hydraulic pres sure.

1. Make sure hydraulic selector valve is in the “Road” position. See Figure 2-1 on page 12.

IMPORTANT: If the planter has set in the folded position for awhile, be sure the wing gauge wheels are fully retracted before beginning to unfold planter. If wheels are not retracted hopper damage will occur when unfolding planter. Retract wheels by lowering planter on transport locks.

2. Begin to unfold planter.

3. When wings have cleared the outside hopper on the center section, raise planter. This will lower the wing gauge wheels.

IMPORTANT: Make sure the wings have cleared the outside hopper on the center section before raising the planter. If raised too soon, the gauge wheels will cause hopper damage.

Before transporting the planter check the following items.

1. Transport only with a tractor of proper size. See Tr ac-

tor Requirements in “Section 9 Speciﬁcations and Capacities” on page 61.

2. Hitch planter securely to tractor. Always use a locking style drawbar pin sized to match the holes in the hitch and drawbar (minimum of 1" diameter heat treated pin).

3. Attach safety chain securely to the planter hitch and the tractor with enough slack in the chain to permit turning.

4. Plug in safety lights with tractor lights using the standard 7-pin terminal.

5. It is recommended that the planter not be transported with full hoppers.

6. Make sure the planter is properly folded. Refer to Fold- ing on page 12.

7. Any time you transport planter, be sure transport locks are in place.

8. Check to see that the tires on the planter have the proper inflation, see the ﬂation Chart” on page 63.

9. Remember, the planter is wider than the tractor and extreme care must be taken to allow for safe clear ance.

10. Transport slowly over uneven or rough terrain.

Rephasing the Hydraulic System

WARNING!

Escaping ﬂuid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic lines. Use a piece of paper or cardboard, NOT BODY PARTS, to check for suspected leaks. Wear protective gloves and safety glasses or goggles when working with hydraulic systems. If an accident occurs, see a doctor immediately. Any ﬂuid injected into the skin must be surgically removed within a few hours or gangrene may result.

Refer to Figure 2-8:

The lift system on your Great Plains Pull-Type Planter is a master/slave system. All cylinders in the system are 2/way cylinders. Rephasing the system is accomplished each time the planter is lowered to the planting position. If unlevel lifting occurs, lower the planter to the ground and hold the remote lever momentarily. This time will allow oil to go from the tractor to the master, bypass to the master, bypass to the slave, then return to the tractor.

Marker Hydraulics

DANGER!

Never allow anyone near the planter when cycling the markers. Excessive travel speed of the markers can be dangerous and/or damage the marker assembly.The ﬂow controls should be properly adjusted before the marker assembly is ﬁrst put into use.

Refer to Figure 2-9:

The marker hydraulic system is equipped with needle valves to control how fast each marker operates. The needle valves are built into the sequence valve body. There are two hex adjustment heads, one for controlling marker speed up and one for controlling marker speed down. To adjust the speed of each marker, loosen jam nut, screw the needle valve clockwise to adjust the marker speed to a low setting. Fold the marker up and down a few times and recheck for pinching and kinking of hoses. With the tractor engine at an operating rpm, adjust the needle valve to limit the marker to a safe operating speed. Excessive folding speeds can cause marker damage.

the hydraulic lever and lower the opposite marker. Holding the lever down then will force both markers down.

If the markers are down they can both be raised simultaneously but they can only be lowered one at a time al-

ternating from one side to the other.

• When oil is cold, hydraulics operate slowly. Make sure

all adjustments are made with warm oil.

• On a tractor where the oil flow cannot be controlled, the

rate of flow of oil from the tractor may be greater than the rate at which the marker cylinder can accept it. The trac tor hydraulic control lever will have to be held until the cylinder reaches the end of its stroke. This occurs most often on tractors with an open center hydraulic system.

On tractors with a closed center hydraulic system, the tractor’ s hydraulic ﬂow control can be set so the tractor’s detent will function properly.

Section 3 Row Unit Operation

Seed Hopper

The row unit is equipped with one 2-bushel translucent seed hopper.

Before ﬁlling the seed hopper, clear it of foreign objects. After ﬁlling the hopper with clean seeds always replace the hopper lid. Operating with the lids attached prevents ob jects from entering the hopper and also aids in keeping out moisture.

Empty the contents of the hopper periodically to avoid the collection of dirt and other materials. To remove the hop per, disengage the meter drive clutch and the hopper latch, see

Figure 3-8.

Great Plains Mfg., Inc.

IMPORTANT: To install Lock ‘n Load®, you must install lid stiffeners. Stiffeners are available through Great Plains, part number 403-075K.

Chemical Hopper

The optional chemical hopper, see Figure 3-9, comes in 2 versions:

• 1 chemical meter and an approximately 70 lb. capacity

translucent hopper.

• 2 chemical meters and 1 divider that separates the 70 lb.

hopper into 2 compartments - approximately 35 lbs. each.

Before ﬁlling each chemical hopper clear it of foreign objects. After ﬁlling each hopper replace the hopper lid. Operating with the lid attached prevents objects from entering the hopper and also aids in keeping out moisture.

Chemical Hopper

Figure 3-9

The application rate is determined by:

1. The size of the opening on the meter housing assembly.

2. The travel speed.

The size of the opening is adjustable by turning the knobs on the rear of the granular hoppers. There are 99 incre ments which indicate the relative application rate. The delivery rate will increase from 1 through 99. Setting 00 closes the opening completely. A ﬂuted roller delivers the granular chemical to the adjustable opening.

The granular chemical ﬂows through a given opening size at a nearly uniform rate regardless or rotor rpm. Therefore, SPEED has the greatest impact on application rate and re sulting chemical concentration in the row.

For example, if planting speed is reduced from 6 to 3 mph, chemical concentration will nearly double since the deliv ery rate through the oriﬁce remains nearly the same while the distance traveled in a given period of time has been cut in half. Therefore, twice as much chemical is placed on the ground due to the decrease in ground speed.

Rotor rpm will minimally change the chemical meter deliv-

Section 3 Row Unit Operation

ery rate unless the seed population is changed signiﬁcantly (i.e. + 25 percent or more from the original setting).

The rate charts starting on page 32 are approximate, and are based on a planting speed of 5 mph. They are to be used only as a guide to determine a starting point for the meter dial setting.

Always check your rate of application as outlined in this section to be sure you are getting the desired rate.

Use the application rate and meter setting recommended by the chemical manufacturer as a starting point for the meter dial setting.

If the meter setting is not available from the chemical manufacturer, use the charts in “Section 5 Planting Rate Ad- justments” on page 30 as a starting point for the meter dial setting.

NOTE: Because the available chemical materials vary widely in consistency and composition, their “ﬂow-ability” is affected by temperature and humidity conditions. It is important to calibrate each individual meter to the partic ular chemical being used.

To determine the application rate and starting meter setting, proceed as follows:

The chemical manufacturer may recommend the rate of application for granular chemicals in the following ways:

1. Ounces per 1000 linear row feet.

2. Pounds per acre for a given band width and row spacing.

3. Pounds per acre for complete (broadcast) coverage.

When the chemical manufacturer recommends ounces per 1000 linear row feet or pounds per acre for a given band width and row spacing, proceed to the chemical manufacturer’s recommended meter setting or to the meter setting recommended in the rate charts.

When the chemical manufacturer recommends pounds per acre for complete (broadcast) coverage only, it is nec essary to reduce the pounds per acre to apply for your band width and row spacing. This will give you the same chemical concentration in the band area as the chemical manufacturer recommends for complete (broadcast) cov erage.

Use the following formula to ﬁnd the pounds per acre for your band width and row spacing.

A - Chemical manufacturers recommended rate in pounds per acre for complete (broadcast) coverage.

B - Band width in inches.

C - Row spacing in inches.

Example: The chemical manufacturer recommends 20 lb/ acre for complete broadcast coverage. The band width is 14 inches. The row spacing is 30 inches.

20 x 14/30 = 9.3 lb. per acre.

The required delivery rate for 14 inch bands and 30 inch row spacing would be 9.3 lb/acre. Set meter setting rec ommended for 9.3 lb/acre broadcast coverage.

Delivery of 9.3 lb/acre of chemical in a 14 inch band will provide the same chemical concentration on the soil sur face as delivery of 20 lb/acre broadcast coverage.

Proceed to chemical manufacturer’s recommended meter setting or to the meter setting recommended in the rate charts in this section which will deliver 9.3 lb/acre.

To check the exact number of lb/acre of chemical that will be delivered, attach a plastic bag to each chemical diffus er, lower the planter, and proceed as follows:

Drive 500 feet at planting speed. Weigh the chemical in oz. that was caught in one bag. Multiply that amount by the factor shown to determine lb. per acre.

Check the chemical caught in each bag in the same manner.

Lb. Per Acre Factor for

Given Row Width

Row Width Factor

30 inch 2.2

Example: Assume you are planting 30 inch rows and you caught 5.6 ounces in one bag (one row).

5.6 ounces times 2.2 equals 12.3 lb. per acre.

If the desired amount is not obtained for each unit with the ﬁrst setting, turn the metering knob and repeat the check until desired amount is delivered.

IMPORTANT: If a signiﬁcant difference in rate is observed between rows, the meter dial mechanism may require recalibration.

IMPORTANT: We recommend you actually measure the band width applied in your conditions and use this width in your application rate calculations.

A X B/C = Delivery rate per acre for a given band width and row spacing.

Meter Drive Adjustments

The alignment between the meter clutch and the input shaft is important. If there is misalignment the meter will not function properly. Excessive wear and damage can also occur to the meter housings. When replacing the meter the vertical and horizontal alignment should be checked.

Check for Vertical Alignment

Refer to Figure 4-4:

1. Latch the appropriate hopper into place on the support.

2. The roll pin in the end of meter input shaft should be centered (equal distances of the roll pin should protrude from both sides of the shaft).

3. Rotate the input shaft so that the roll pin is vertical.

4. Rotate the drive coupler so that the slots are vertical.

5. Release the clutch to engage the drive coupler with the input shaft.

If the alignment is correct the coupler will engage with the shaft freely and the roll pin will extend equally on each side of the coupler. Disengage the clutch and check the horizontal alignment.

Seed Lok® (Optional)

The Seed Lok® option provides additional seed to soil contact. The Seed Lok® is spring loaded and does not require adjusting. In some wet and sticky conditions the wheel may accumulate soil and may require removal of the Seed Lok® until conditions improve.

The Seed Lok® is attached to the shank with a 1/2” clevis pin, see Figure 4-15. To remove the Seed Lok®, remove the clevis pin and pull down on the Seed Lok® mount.

Reattach in the reverse order.

Tire Scraper (Optional)

Some soil types may require the use of the optional tire scraper. The scraper prevents an excess of mud from building up on lift tire that may hamper the contact drive tire. Adjust the scraper so it does not contact the tire. See Figure 4-16.

Planting Rate

Transmission Adjustment

To change planting population, change the sprocket combination on the transmission.

1. Refer to “Planting Rates for Finger Pickup Corn Meters” on page 32 for the proper sprocket combina- tion for your desired planting population.

2. Remove the cover from the transmission by loosening the knob on the cover.

Left-Hand Planter Transmission

Figure 5-1

3. Loosen the carriage bolt and ﬂange nut on the idler plate. Rotate the idler plate to move the idlers out of the chain.

4. Remove the chain. Remove sprockets currently on transmission shafts.

5. Find the correct sprockets on the storage brackets and place on the transmission shafts.

NOTE: When not in use, store all extra sprockets on the storage bracket.

6. Place the sprockets on the drive/driven shafts.

7. Re-route chain over idlers and sprockets.

8. Turn the idler plate to take up chain slack. Chain should have a maximum of 1/4-inch slack.

9. Retighten the carriage bolt and ﬂange nut to secure idler plate.

10. Replace the transmission cover and hand tighten the knob.

2-to-1 Drive Reduction

The 15/28 tooth drive sprocket located on the inner side of the contact drive wheel assembly will give you a 2-to-1 drive reduction and reduce planting rates by about onehalf.

NOTE: After each sprocket combination adjustment, make a ﬁeld check to be sure you are planting at the desired rate.

16863

2-to-1 Drive Reduction

Figure 5-2

Checking Planting Population

After setting the transmission or contact-drive reduction, always ﬁeld check the planting population as follows.

1. Release spring pressure on opener disks and wheels.

2. Tie up closing disks and wheels to hopper support using a chain or heavy wire. Pin up optional Seed-Lok wheels

3. Adjust the planting depth to a shallow setting.

4. Plant at a normal speed for a short distance.

5. For 30-inch rows, measure 17 feet 6 inches (one-thousandth of an acre.)

6. Count the number of seeds in one row over the measured distance.

7. Multiply the number of seeds counted by 1000. This gives you total population.

Example

• 30-inch row spacing

• Measure 17 feet 6 inches

• 24 seeds over measured distance in one row

24 X1000 = 24,000 plant population per acre

If the planting population is signiﬁcantly different than the desired, make the following checks.

• Double check the sprocket combination in the transmission. Refer to the “Planting Rates for Finger Pickup Corn Meters” on page 32.

• Check air pressure in the gauge wheel tires. Refer to Tire Inflation Chart,

“Appendix” on page 63.

• Check for meter malfunction or excessive contactdrive-wheel slippage. Refer to

“Section 6 Trouble-

shooting” on page 39.

Section 5 Planting Rate Adjustments

Great Plains Mfg., Inc.

Planting Recommendations

To get the best planting results, follow these recommendations:

• Plant at 5 mph

• Add 1 teaspoon of graphite to each seed hopper.

• Maintain tire pressure in the gauge tires and drive tires.

• Replace worn meter parts. Drive Wheel Slippage

Another item that may cause the actual rates of seed or fertilizer to differ from the delivery rates shown in the oper ator’s manual is the amount of drive wheel slippage.

While a certain amount of wheel slippage is normal, excessive drive wheel slippage may cause undesirable changes in the actual rates.

Excessive drive wheel slippage may be caused by binding or poorly lubricated parts, misaligned bearings or caked material in the pesticide or fertilizer hoppers.

In addition, down pressure springs, coulters, tine tooth attachments, or any other attachment that removes frame weight from the drive wheels, may contribute to drive wheel slippage and lower than expected rates.

If in-ﬁeld checks indicate that the planter is planting at a rate signiﬁcantly different than the seed transmission rate chart indicates, investigate the following in the order listed:

• Ensure that ALL transmission sprockets are set accord-

ing to the rate chart.

• Excessive unit bounce can cause low population and re-

duced spacing control. Reduce excessive unit bounce by increasing unit down force, or drive slower.

• Ensure that the planter drive wheel slippage is close to

normal. Variations in drive wheel slippage can be caused by crop residue, tire inflation pressure, soil con ditions and unit down force.

Adjusting Granular Chemical Rates

The optional chemical applicators are adjusted by varying the opening on the chemical meter housing. The ﬁeld check is very important because temperature, humid ity, speed, ground conditions, ﬂowability of chemicals, and obstructions affect the application rate.

4. Attach a plastic bag to each chemical

diffuser.

5. Drive 1320’ at a normal planting speed.

6. Weigh the contents of the bag in ounces.

7. Multiply ounces by 0.83 to determine the pounds

per acre.

8. If required, adjust the meter setting and repeat steps 3

through 7 until the desired rate is reached.

DANGER!

Agricultural chemicals can be dangerous if not selected and handled with care. Always read and follow directions supplied by the chemical manufacturer.

On machines equipped with the squeeze pump option, the

rate of liquid fertilizer application is determined by the

combination of sprockets on the squeeze pump driven and drive shafts. When changing sprocket combinations, make sure sprockets are in alignment, sprocket retaining collars are tight and chain tension is sufﬁciently restored.

The Liquid Fertilizer Rates on page 35 provide an approximate application rate only. Actual delivery will vary with temperature and the particular fertilizer being used.

14914

DANGER!

Agricultural chemicals can be dangerous if not selected and handled with care. Always read and follow directions supplied by the chemical manufacturer.

To adjust the chemical rate do as follows:

1. Select a setting from the Insecticide/Herbicide Appli- cation Rates starting on page 36, as a starting point.

2. Turn the knob on the chemical meter until the display shows the appropriate number, see

3. Fill the hoppers with chemical.

Fasteners

When working on the planter torque all bolts, screws, and nuts to the correct values listed in the

Torque Values Chart

for Common Bolt Sizes in “Appendix” on page 63. Check

latches and other fasteners on the planter to prevent failures in the ﬁeld.

Replacing Shear Pins

Refer to Figure Figure 7-3.

The cotter pins (1) that connect the transmission-input and

-output shafts to the transmission will shear when an ex cessive load is put on the shafts.

Infrequent or improper lubrication causes binding of moving parts within the planter. This binding will cause the cotter pins to shear, thus preventing breakage of planter parts.

Check for binding by turning the drive shaft with all seed hoppers installed and seed meters engaged. If the drive shaft is hard to turn, disengage one seed-meter clutch at a time to ﬁnd the problem clutch.

Improper shaft alignment can also cause pins to shear. Refer to Shaft Alignment, this page, to check shaft align ment.

When the drill shaft can be turned freely by hand, replace the cotter pin.

IMPORTANT: Only replace the cotter pins with cotter

pins of the same size. Do not replace with other type

pins.

Shaft Alignment

Improper alignment of the transmission-input and -output shafts can cause pins to shear. To function properly, the shafts must be aligned and level. If the planter is consis

tently shearing pins, follow these steps to check and adjust the shafts.

1. Check that the transmission-input shaft (1) and trans-

mission shaft (2) are aligned. Remove cotter pin from coupler sleeve. Pull the coupler sleeve back and ob

serve the shafts.

Finger Pickup Meter

Inspect and repair the ﬁnger pickup meter by removing the 2 bolts holding the meter to the hopper. Remove the 3 bolts on the meter bafﬂe to gain access to the ﬁnger mech anism.

Rotate the meter input shaft by hand to check the ﬁngers. The ﬁngers should be against the carrier plate in closed area and raised in open area as shown in

Figure 7-8.

To clean the corn meter:

1. Remove the cotter pin, lock nut, and adjusting nut from the shaft.

2. Lift the ﬁnger assembly off the shaft and clean.

3. Replace worn ﬁnger assembly by lifting the ﬁnger out of the slot. Average life expectancy of these parts should be 250-300 acres of row operation. When ﬁn gers are replaced, the open end of the spring loop should be toward the inside of the ﬁnger housing.

4. Inspect the indentations in the carrier plate for wear. Replace carrier plate when wear to the plate becomes excessive or the seeding accuracy will be affected.

5. Reassemble the meter in reverse order. Be sure the ﬁngers are installed correctly so the ﬁnger housing is ﬂush with the carrier plate. If the ﬁnger housing is not ﬂush with the carrier plate, make sure that the projec tion on the cam is in the notch on the bearing housing. The meter will not function properly if the projection is not in the notch.

6. With the ﬁnger assembly against the plate, tighten the adjusting nut until it is snug. Then turn an additional 1/3 turn. Turn the meter by hand making certain that the meter is not over tightened. Proper meter resis tance would be 22-25 in/lbs of torque applied at the meter input shaft.

7. Install the cage nut and the cotter pin.

8. Install the bafﬂe and attach the meter to the hopper.

Check the belt on the meter periodically.

IMPORTANT: Check tightness of the adjusting nut on the meter after the ﬁrst day and periodically thereafter.

Use these steps:

1. Remove the 4 bolts (#1) located on the belt housing, the bolt holding the belt roller and the belt housing cover (#2). See

Relaxing Pressure on Metering Hoses

Figure 7-14

12409

Although the tanks are made of a highly durable and corrosion resistant plastic, proper maintenance is required.

Rinse the tank with water when changing from one solution to another.

Rinse tank thoroughly with water after each season or before any shutdown lasting over one week.

Do not allow sludge to accumulate in the bottom of the tank.

Do not leave fertilizer in the tanks if the temperature is expected to drop below 40 degrees as some types of liquid fertilizers will begin to crystallize at this temperature.

To clean tanks, proceed as follows:

5. Remove lids from tanks.

6. Turn valve to elbow.

7. After cleaning tanks, close shutoff valve, replace cap on metering pump and replace lids on tanks.

Squeeze Pumps

Refer to Figure 7-14:

During periods when the pump is not being used, these important steps are recommended to prevent hose defor mation and prolong hose life.

1. Unscrew (about 1/2 inch) the wing nuts holding the spring anchor bar to the pump frame. This releases pressure against the hoses.

2. Loosen the wing nuts on the discharge manifold and shift the manifold rearward.

3. Store out of sunlight.

Marker Breakaway Protection

The marker arm is attached to the marker body with a 5/16" breakaway bolt. If excessive force is put on the marker during operation, the bolt will break, allowing the marker arm to swing away rather than cause damage to the marker.

IMPORTANT: The breakaway bolt is a 5/16"-18 x 1 1/ 2" long grade 2 on planter only (GP #802-295C). If it breaks, it must be replaced by an equivalent grade 2 bolt to prevent marker damage.

Storage

To extend the life of your planter follow the recommendations for removing the planter from storage and storing the planter during the off season.

Beginning of the Season Service

Before using the planter after it has been stored, inspect the seed hoppers for cleanliness to be certain the seed will

ﬂow from hoppers freely.

Thoroughly inspect the planter unit for loose parts and adjust as necessary. Check all bolts and replace worn parts to prevent failure in the ﬁeld.

Clean any dirt or grease that may have accumulated on moving parts, and chains before operating the planter. This will prevent abrasive action that could cause exces sive wear.

PT1230 Pull-Type Folding Planter 401-069M-A 10/10/12

Great Plains Mfg., Inc.

Section 7 Maintenance and Lubrication

When roller chains remain unused for several days, moisture in the air will accumulate on the chain, causing the chain to rust. This can, and will, become serious enough in time to cause the chain joints to become stiff, restricting their normal free movement. While very difﬁcult to detect, this stiffness can encourage the chains to operate abnormally and disturb the smooth rotation of important meter components, causing deterioration in performance.

If the planter is not used for several days, or if oil has been removed from chains, etc. while cleaning the planter thoroughly lubricate chains with multipurpose chain lube.

NOTE: Do not use chain lube or any other heavy petroleum base lubricant that may cause a buildup of dust or dirt in the sprocket or gear teeth.

Turn the meter drive shaft by hand to be sure the drive shaft and seed meter are free to turn. Rotate forward only, as assemblies are not designed to rotate in reverse.

Be certain all adjustments are made for the planting conditions to be encountered.

Service at the End of the Season

When planting is complete clean the seed and chemical hoppers. Remove all dirt, debris, chemicals, and fertilizer from the planter that may hold moisture and cause corrosion.

Use spray paint to cover scratches, chips, and worn areas on the planter to protect the metal.

Lubricate the planter as outlined in Lubrication. Pay careful attention to the lubrication of the chains to help prevent rusting.

Inspect the planter for worn or damaged parts. Make repairs and service during the off season to reduce down time in the field.

Place the 1 X 12 closing wheel handle in the middle slot to relieve the tension on the closing wheels. Move opener adjustment bar on heavy and medium down pressure spring packages to hole A, refer to Figure 4-7 on page 26.

Remove the finger pickup meters from the hoppers. Disassemble the meters and inspect them for wear. Make any repairs required at this time. Blow excessive debris from the meter. Wash the meters with mild soap and water. Dry the meters and spray a light coat of rust inhibitor on the meters. Reassemble and store in a dry place.

Thoroughly ﬂush liquid herbicide system with clean water. Disconnect from tractor and completely drain all lines and components to prevent damage from freezing.

Store the planter in a clean, dry place with all tires out of the sun. A sheltering structure is best for overall protection, but a high quality tarp would suffice.
