between  the  tailwheel frame and deck lugs.(Figure 3-1)

SECTION III

OPERATING INSTRUCTIONS

3-1 GENERAL SAFETY

Only  qualified  people  should  operate  this  machine.
Operator  should  wear  hard  hat,  safety  glasses  and
safety  shoes.    It  is  recommended  that  tractor  be
equipped  with  Rollover  Protective  Systems  (ROPS)
and  a  seat  belt  be  used.    Before  beginning  opera-
tion,  clear  work  area  of  objects  that  may  be  picked
up and thrown.  Check for ditches, stumps, holes or
other  obstacles  that  could  upset  tractor  or  damage
cutter.  Always  turn  off  tractor  engine,  set  parking
brake, and allow cutter blades to come to a complete
stop before dismounting tractor.

3-2 ADJUSTING FOR WORK

The cutter should be operated at the highest position
which will give desired cutting results.  This will help
prevent the blades from striking the ground, reducing
blade  wear  and  undue  strain  on  the  machine.    For
best results under heavier cutting conditions, always
tilt the cutter approximately 2 inches (51mm) lower in
the  front.    This  tilt  decreases  horsepower  require-
ments and increases potential ground speed.  When
fine shredding is desired, adjust cutter deck level or
slightly  lower  in  the  rear.    This  will  keep  the  foliage
under cutter until thoroughly shredded.  More power
is required for shredding.

3-2.1 CUTTING HEIGHT ADJUSTMENT

THE  CUTTER  CAN  FALL  FROM  HYDRAULIC 
SYSTEM  FAILURE.    TO  AVOID  SERIOUS
INJURY  OR  DEATH,  SECURELY  SUPPORT 
CUTTER BEFORE WORKING UNDERNEATH.

SHIELDS  IN  PLACE  AND  IN  GOOD  CONDI-
TION.  FAILURE TO HEED THESE WARNINGS 
MAY  RESULT  IN  PERSONAL  INJURY  OR 
DEATH.
