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.

BOLT TORQUE
Mounting bolts and hardware
Before operating the 2910 Frame Mounted Coulter for the first time, check to be sure that
all hardware is tight. Check all hardware again after approximately 50 hours of operation
and at the beginning of each planting season.
All hardware used on the 2910 Frame Mounted Coulter is Grade 5 unless otherwise
noted. Grade 5 cap screws are marked with three radial lines on the head. If hardware
must be replaced, be sure to replace it with hardware of equal size, strength and thread
type. Refer to the torque values chart when tightening hardware.
Important: Over tightening hardware can cause as much damage as when
under tightening. Tightening hardware beyond the recommended range can reduce
its shock load capacity.
The chart below is a guide for proper torque. Use it unless a specified torque is called out
elsewhere in the manual.
Torque is the force you apply to the wrench handle or the cheater bar, times the length of the
handle or bar.
Use a torque wrench whenever possible.
The following table shows torque in ft. lbs. for coarse thread hardware.
Lubricate all bearings and moving parts as assembled and make certain that they work freely.
WARNING: Never work around the toolbar/implement while in a raised position without using
safety lockups.
CAUTION: The 2910 Frame Mounted Coulter attachment is very heavy. Pay extra attention to
lifting techniques while handling and or maneuvering the opener during assembly. Failure to
do so may lead to personal injury.

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. Recheck 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.
5
OPERATION
IMPORTANT: For proper operation, the planter frame must operate
level and at the correct height, usually 20” – 22” while in operation.
In hard no-till conditions the desired operating depth may not be possible. Tighten spring
nut to maintain depth if spring is flexing rather than lower coulter to obtain maximum
depth. Planter weight may limit operating depth in hard conditions, particularly with
mounted or semi-mounted planters. Be sure planter has enough weight to keep drive
wheels on the ground during operation or plant populations can be drastically affected.
1.
Set/mount coulter blades to run perpendicular to the soil. Operation depth and blade
wear can be affected if the coulter is mounted crooked or if the toolbar is not level side to
side.
2.
After a few hours of use, check all bolts for tightness and proper torque.
3.
After a day of use (10-12 hours) check coulter hubs for loose bearings. There should be
no endplay in the hub bearings allowing the blade to wobble. If necessary, remove
hubcap and cotter pin and adjust the slotted nut to remove wobble, recommended torque
of 15 ft. lbs. and re-insert cotter pin. If the wobble or looseness cannot be corrected, the
bearings, cups and seals will need to be replaced.
DO NOT USE WORN OR DAMAGED PARTS.
6
MAINTENANCE
LUBRICATION: USE #2 MULTI-PURPOSE BEARING GREASE
To ensure longevity and reliability of the U.N.T. Coulter, the recommended lubrication
schedule should be followed using multi-purpose grease at hourly intervals as indicated.
BEARING ADJUSTMENT:
1. Raise the toolbar until the blade is clear of the ground. Place a safety stand under the toolbar.
Remove the hubcap, cotter pin, slotted nut and washer from the hub assembly. Remove the blade
from the hub assembly.
2. Remove bearing cones and seals from hub.
3. Wash the old grease from the hub, bearing cups, spindle spacers, seals and bearing cones.
Inspect the condition of the bearing cups, cones and seals. Replace if necessary.
4. Apply #2 multi-purpose lithium grease on each bearing. Make sure the space around each roller is
filled. Lubricate the bearing cups.
5. Position the bearing in the cup and install the seal. Lubricate the seal lips and proceed with reassembly of the removed parts including the blade. Blade bolt torque is 90 to 96 ft. lbs.
6. Tighten the slotted nut to 15 ft. lbs. or until a definite drag is felt when the blade is turned by hand.
Tighten the nut one slot position to line up the cotter pin hole with a slot. Secure the nut with a new
cotter pin, replace hubcap.

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.
