We hope your new Yetter products will help you

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.

(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

     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.
