SAFETY

A brief description of signal words that may be used in this manual:

CAUTION: Used as a general reminder of good safety practices or to direct attention to unsafe practices.

WARNING: Denotes a specific potential hazard.

DANGER: Denotes the most serious specific potential hazard.

SAFETY PRECAUTIONS

You can make your farm a safer place to live and work if you observe the safety precautions given. Study
these precautions carefully and insist that those working with you and for you follow them.

Finally, remember this: an accident is usually caused by someone’s carelessness, neglect or oversight.

WARNING

Never clean, lubricate or adjust a machine that is in motion. Always lower or block the implement before
performing service.

If the machine must be serviced in the raised position, jack or block it up to prevent it from accidentally
falling and injuring someone.

Do not allow riders on the tractor or implement.

Use speeds and caution dictated by the terrain being traversed. Do not operate on any slope steep enough
to cause tipping or loss of control.

Be sure all personnel are clear of the immediate area before operating.

Read and understand the operator’s manual and require all other persons who will operate the equipment to
do the same.

Be familiar with all tractor and implement controls and be prepared to stop engine and implements quickly in
an emergency.

CAUTION

Consult your implement and tractor operator’s manual for correct and safe operating practices.

Beware of towed implement width and allow safe clearance.

FAILURE TO HEED MAY RESULT IN PERSONAL INJURY OR DEATH.

GENERAL INFORMATION

The 2959 Fertilizer Coulter can be used as a R.H. opener or a L.H. opener, it is recommended that half of
the planter is R.H. assemblies and the other half is L.H. assemblies.

NOTE: The 2959 Fertilizer Coulter is NOT recommended for use in rocky conditions as the coulter arm and
fertilizer tube are susceptible to bending.

For proper operation of the 2959 coulter, a ¼” NPT “Straight Stream” nozzle or a ¼” NPT Female “Nozzle
Body” with orifice plates will be required. Yetter Manufacturing Co. does not supply these parts.

See tip application chart.

BOLT TORQUE

READ THESE INSTRUCTIONS FIRST:

1. Improperly tightened bolts will result in damage, breakage, expense, and down time.

2. Always replace bolts with the specified grade and type.

3. Torque properly before first use of the machine and every 2-4 hours of use until you are sure bolts are
staying tight.

4. The chart below is a guide for proper torque. Use it unless a specified torque is called out elsewhere in
the manual.

5. Torque is the force you apply to the wrench handle or the cheater bar, times the length of the handle or
bar.

6. Use a torque wrench whenever possible.

The following table shows torque in ft. lbs.

ASSEMBLY INSTRUCTIONS

STEP 1. Attach the 2959-203 fert. coulter faceplate w.a. to the planter unit using 3) ½-13 x 1 ½”

bolts, flat washers and locknuts. Use the 1 ¾” OD x ¼” thick washer on the lower large slot. On
some planter units, this washer may need to be trimmed enough not to interfere with a gusset.
Center the bracket on the row unit and tighten the bolts to specification listed on the table on page 4.

STEP 2. Attach the coulter arm 2959-201 to the faceplate using 2) ½-13 x 2 ¾” bolts, flat washers
and lock nuts.

NOTE: The unit-mounted coulter can be assembled as a right hand or left hand coulter
assembly.

ASSEMBLY INSTRUCTIONS

STEP 3. Depth settings are in reference to the planter frame being level (front to back) when in

planting position. Depth settings are in relationship to the planter disc opener blades being 15” in
diameter and the fertilizer coulter blade being 16” in diameter. The coulter blade has 6
adjustment settings in a 2” range, with a maximum operating depth of 4” below the surface.

EXAMPLE: Planting depth is set at 1 ½” then the coulter placement may be adjusted to 1 ½” to 3
½” below the surface of the ground.

STEP 4. Attach the 2959-200 Injection tube holder to the coulter arm on the same side that the
coulter hub is assembled using 2) 3/8-16 x 1 ½” bolts and lock nuts. Insert the 8” pipe nipple and
coupler into the tube holder and attach a hose to the fertilizer tube and tighten hose clamps (NOT
SUPPLIED).

6

ASSEMBLY INSTRUCTIONS

STEP 5. At the pipe coupler install the appropriate nozzle (not supplied) according to the

liquid fertilizer application rate. Nozzles can be ordered through your nearest implement
dealer or fertilizer equipment dealer. See the tip application chart in this manual.

STEP 6. Attach the coulter blade to the arm/hub assembly using 4) ½-13 x 1 ½” carriage
bolts, lock washers and hex nuts.

OPERATION PRECAUTIONS

STOP

Read this before using the Yetter product.

- MACHINE OPERATION

IMPORTANT: failure to properly set the planter frame height and
levelness can result in less than successful operation of the planter
and the Yetter product and may result in damaged equipment.
operators should read and thoroughly understand the instructions
given prior to using the Yetter product.

NOTE: DO NOT use this product if the planter is not adjusted properly!

Leveling the planter:
With the planter lowered to proper operating height (Usually 20”-22”).
Read the planter operator’s manual for recommended setting. Check to
be sure the toolbar and row unit parallel arms are level fore and aft. Re-
check when the planter is in the field and has been fully loaded with seed,
fertilizer, granular chemicals, etc. Also, a field check with a bubble level on
the frame should be made of the hitch height to ensure level operation front
to back.

It is important for the planter to operate level laterally. Tire pressure must
be maintained at pressures specified by the manufacturer.

Field and actual planting conditions change and will dictate planter frame
heights. You must ensure that the row unit parallel arms are approximately
parallel with the ground.

IMPORTANT: For proper operation of the planter attachments and row
units, it is imperative that the planter toolbars and row unit parallel arms be
level side-to-side and front-to-rear. The toolbar frame should operate at a
20”-22” height from the planting surface
operator’s manual for instructions on how to adjust the frame height and
levelness.

. Check the manufacturer’s

PARTS IDENTIFICATION

Problem

Row unit floats out of soil

Planter pulls to one side

Damage/Breakage of blade
shaft, coulter arm and or blade

Bending or breakage of
fertilizer tube

Fertilizer splatter

TROUBLESHOOTING

Cause

Insufficient down pressure

Planter frame not level for and
aft

Soil too hard/compacted

2959 fertilizer coulter blade
adjusted too deep

Not an equal number of RH
and LH coulter assemblies

Turning with blades in ground

Extreme soil conditions such
as very tight soil or heavy
rocks, especially combined
with:
A: speed is too fast
B: blades too deep
C: turning with blades in
ground

Tube/nozzle adjusted too low

Heavy rock conditions

Nozzle not aligned with furrow

Liquid pressure is too high
(PSI) pounds per square inch

Solution

Increase the tension of the
planter unit down force
springs

Level the frame at 20” frame
height while in planting
position

May have to use a tillage
implement to loosen soil

Raise the coulters. Coulters
could hold planter out of
ground if set too deep

Assemble equal number of
RH and LH coulter assemblies

Avoid this

Avoid whenever possible
otherwise:
A: reduce speed
B: run blades only deep
enough to place fertilizer
C: do not turn with blades in
ground

Raise nozzle to a minimum ½”
above soil

Install 2959-104 spring loaded
injection kit

Ensure each nozzle is directly
behind and centered on the
coulter blade furrow

Recommended PSI is 20 to

30. Adjust and recalibrate
system for different pressure
setting.

LIQUID FERTILIZER APPLICATION RATE AND PRESSURE CHART

TABLES ARE BASED ON 30” NOZZLE SPACING

GPA = 5940 X GPM H20 = WATER SOLUTION FACTOR
(Per Nozzle) MPH X W GPA = GALLON PER ACRE 28% = H20/1.13

GPM = GALLON PER MINUTES 32% = H20/1.15

MPH = MILES PER HOUR

W = WIDTH
