The purpose of this manual is to assist you 

in  operating  and  maintaining  your  Disc 

Harrow. Read it carefully. It furnishes infor-

mation  and  instructions  that  will  help  you 

achieve  years  of  dependable  perfor-

mance.
These  instructions  have  been  compiled 

from  field  experience  and  engineering 

data. Some information may be general in 

nature, due to unknown and varying oper-

ating conditions. However, through expe-

rience and these instructions, you should 

be able to develop procedures suitable to 

your particular situation.

The  illustrations  and  data  used  in  this 

manual were current at the time of print-

ing. However, due to possible inline pro-

duction changes, your machine may vary 

slightly  in  detail.  We  reserve  the  right  to 

redesign  and  change  the  machines  as 

may be necessary without notification. 
Throughout  this  manual,  references  are 

made to right and left direction. These are 

determined by standing behind the tractor 

facing the direction of forward travel.
