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 they be followed by those working with you and for you.
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 install the transport lock pins and bracket when
transporting for any length of time or on public roadways.
If required to service unit in raised position, be sure to install all transport lock pins and locking bracket.
Do not allow children to operate this equipment.
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.
In operating on public roadways, where legal, be certain all lighting is operating properly and observe all traffic laws.

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. All
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. Check the manufacturer’s
operator’s manual for instructions on how to adjust the frame height and
levelness.

PLANTER ADJUSTMENT

INTRODUCTION
The 2960 Series II Unit Mounted Conservation Coulter has been designed as a ‘universal’ fitment for
several makes of planter units.
By using two different arrangements of the same parts, the one boxed unit will fit several planters. One
arrangement will fit the John Deere MaxEmerge 2 and plus type planters. Another arrangement of the
same part will fit the old style 7000 John Deere units and Kinze units; and the coulter only will fit the 9000
Series New Idea and White 6100 units. The coulter is available separately as 2960-127, the spring kit is
available separately as 2960-126 or the coulter and spring kit can be ordered as a kit 2960-015. Various
different styles and sizes of blades are available to suit particular field conditions, see page 8.

HEAVY DUTY COULTER INSTALLATION
NOTE: Mounting hardware included in 2960-122 bolt bag.
1. Mount the universal unit coulter bracket to planter breast plate using three ½” x 1 ½” bolts, washers
and locknuts. Use the ¼” thick washer on the lower large slot, do not tighten fully yet.
NOTE: The 9/16” dia. round hole is not used on this application, disregard this hole.
2. Mount unit coulter arm to unit coulter bracket using ½” x 2 ½” bolt, flat washers and locknut through
slots in bracket and upper hole in the arm and ½” x 2” bolt and locknut through desired lower holes
of bracket and arm.
3. Install blade on hub using four ½” x 1 1/4” carriage bolts, lock washers and nuts.
4. Align coulter blade with opener blades by sliding bracket on breast plate, then tighten the bolts
securing the bracket to the planter unit.
5. Adjust coulter depth as required. Please note that the minimum depth setting of this coulter on
the Deere 7200 and 1700 series planters is even with the opener discs. As the blade wears,
the coulter may be adjusted to compensate.

DOWN PRESSURE SPRING INSTALLATION
FOR JOHN DEERE 7000/7200/1700
NOTE: Mounting hardware included in 2960-123 bolt bag.
1. Remove the front lower parallel link pivot bolts and spacers. Do not discard the
spacers, as they must be re-used. Install spring anchor castings to the front
lower pivot of the parallel link using new longer bolts and spacers as shown.
NOTE: On John Deere 7000 the short stubs on the castings mount to the outside
and the castings mount on the outside of the parallel links, most other planters IE:
Yetter & Kinze also assemble as 7000. On John Deere 7200 and 1700 series the
short stubs on the castings mount to the inside and the castings mount on the
inside of the parallel links.’
2. Remove the front upper parallel link pivot bolts and spacers and install front bar to
the upper front of the parallel link using new longer bolts and spacers provided,
along with the existing spacers just disassembled.
3. Assemble springs and spacers to spring bar as shown in the appropriate drawing
and secure with cotter pins.
4. Lower this assembly onto the parallel links with the two middle adjustment holes on
the spring bar facing up as shown. This allows maximum down pressure
adjustment.
5. Assemble spring bar over the guide pin on the front bar and secure the ends of the
springs to the spring anchors using ¼” x 2” roll pins. It will be necessary to have
planter units in transport position to install springs, or adjust tension.
6. Insert spring adjustment pin in the desired hole on the spring bar and secure with
1/8” hairpin cotter.
7. Assemble the spring stops to the upper parallel arms with the ½” x 2” bolts and
locknuts provided. The spring stops must be assembled on the ‘inside’ of the arms
and the heads must be towards the middle of each row unit. The spring stops are
to be assembled to the rear ‘spare’ hole in the upper parallel arms and will prevent
the springs from sliding back too far.
8. Refer to ‘Troubleshooting’ page if necessary.

Our name
Is getting known
Just a few years ago, Yetter products were sold primarily
to the Midwest only. Then we embarked on a program of
expansion and moved into the East, the South, the West and
now north into Canada. We’re even getting orders from as far
away as Australia and Africa.
So, when you buy Yetter products . . .you’re buying a name
that’s recognized. A name that’s known and respected. A name
that’s become a part of American agriculture and has become
synonymous with quality and satisfaction in the field of
conservation tillage.
Thank you.
