tractor  be  equipped  with  ROPS  and  seat  belts.  Use
the loader dump cylinders to give the forks the desired
tilt. Position the forks on notched frame member to the
desired width so that the load will be carried approxi-
mately  equal  on  each  fork.  Position  load  as  far  back

The  quick  hitch  (Figure  3-4)  is  designed  to  allow
easy mounting and dismounting of attachments from
loader. With attachment on flat, level surface, mount
as follows:

Tilt  quick  hitch  slightly  forward  at  top  and  slowly
drive into attachment.

Hook  quick  hitch  under  top  cuff  on  attachment  and
lift off ground using boom cylinders only.

Tilt  quick  hitch  backward  so  that  bottom  of  attach-
ment will swing into position. Release spring-loaded
pins into place behind hitch lug for operation.

To dismount the attachment:
Tilt  quick  hitch  backward  and  rotate  handles  up  to
disengage pins. Reverse the mounting procedure.

use  tractor  flashing  warning  lights  unless  prohibited
by  law.  Carry  load  as  low  as  possible  maintaining
adequate  ground  clearance  and  good  visibility.
Reduce tractor ground speed when carrying a load.
Take extra care when traveling over rough terrain or
on slopes.

CAUTION

WHEN  TRANSPORTING  A  LOAD,  KEEP
THE ATTACHMENT AS LOW AS POSSIBLE
TO  RESIST  TIPPING  IN  CASE  A  WHEEL
DROPS IN A RUT.
