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 those working with you and for you follow the precautions.
Finally, remember this an accident is usually caused by someone’s carelessness, neglect or oversight.
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.
CAUTION
Consult your implement and tractor operator’s manual for correct and safe operating practices. Be aware of
towed implement width and allow safe clearance.
CAUTION: SAFETY SIGNS
Safety decals are placed on the implement to alert the operator and others to the risk of personal injury or
unsafe operation during normal operations and servicing.
1. The safety decals must be kept clean and in good condition to ensure that they are legible.
2. Safety decals must be replaced if they are missing or illegible.
3. When components are replaced during repair or servicing, check that the new components include the
necessary safety signs.
4. Replacement safety decals may be obtained from your local dealer.
WARNING
Read these instructions carefully to acquaint yourself with the attachments. Working with unfamiliar equipment
can lead to accidents.
Never clean, lubricate or adjust a machine that is in motion.
If 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 children to operate this equipment.
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.
If operating on public roadways, where legal, be certain all lighting is operating properly and observe all traffic
laws.
Attach a slow moving vehicle emblem to the rear of the trailing implement.
Beware of increased stopping distances and control effort when operating with implements attached.
Be familiar with all controls and be prepared to stop engine and equipment quickly in an emergency.
FAILURE TO HEED MAY RESULT IN PERSONAL INJURY OR DEATH.

BOLT TORQUE
Mounting bolts and hardware
Before operating the 2963 CHALLENGER 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 2963 CHALLENGER 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

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.

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.
