ROTATING  CUTTER  BLADES.    STAND 
CLEAR  UNTIL  ALL  MOTION  HAS  STOPPED.   
TO  AVOID  AN  ACCIDENTAL  FALL  FROM 
THE  TRACTOR  AND  POSSIBLE  INJURY  BY 
THE  MOWER,  IT  IS  RECOMMENDED  THAT 
THE  TRACTOR  BE  EQUIPPED  WITH  ROPS 
(ROLLOVER  PROTECTIVE  SYSTEM)  AND 
THAT A SEAT BELT BE USED BY THE OPER-
ATOR FOR ALL MOWING OPERATIONS.

F. Place tractor in gear and begin cutting.  Tractor for-

ward  speed  should  be  controlled  by  gear  selection,
not engine speed.  
For maximum cutting efficiency, for-
ward  speed  should  allow  cutter  to  maintain  a  constant,
maximum blade speed.  Do not exceed 5 mph (8kph).  If
PTO  drive  is  disengaged  due  to  cutter  stalling  or  tractor
engine  bogging,  cutter  must  be  moved  to  a  “cut”  area
and  tractor  throttle  reduced  to  idle  before  re-engaging.
Always  cut  up  and  down  the  face  of  slopes,  never
across.

ALL  ROTARY  CUTTERS  HAVE  THE  ABILITY 
TO  DISCHARGE  OBJECTS  AT  HIGH  SPEEDS 
WHICH  COULD  RESULT  IN  SERIOUS  INJURY 
TO BYSTANDERS OR PASSERS-BY.

THEREFORE,  THIS  CUTTER  IS  NOT  TO  BE 
OPERATED  ALONG  HIGHWAYS  OR  IN  ANY 
AREA  WHERE  PEOPLE  MAY  BE  PRESENT 
UNLESS  ALL  SIDES  OF  THE  UNIT  ARE 
ENCLOSED  BY  PERMANENT  BANDS,  SAFE-
TY  CHAINS,  OR  OTHER  FACTORY  APPROV-
ED  SAFETY  SHIELDS  THAT  ARE  IN  GOOD
REPAIR.    CEASE  MOWING  WHENEVER  ANY-
ONE COMES WITHIN THE OPERATING AREA.

3-4 TRANSPORTING

When implement is transported on road or highway, day
or night, use tractor flashing warning lights unless prohib-
ited by law.  A slow moving vehicle (SMV) sign must be
visible  from  the  rear  by  approaching  vehicles.    Do  not
exceed  15  mph  (24kph)  when  traveling.    Fully  raise
implement before transporting.
