WORKING POSITION AND ADJUSTMENTS
The GA 7301 raking width can be set in 4 different
positions from 6.70 m / 22' to 7.30 m / 24'. Adjustment
is carried out as follows :
- With the machine in transport position (rotors lifted),
select working width by locking rods (T) in one of the
4 elongated holes (O) of the selector plates (L)
(photo 32).
- The machine can now be lowered into working
position.
NOTE : Make sure rods (T) are positioned in the
same elongated hole number on each ro-
tor.
To fold the machine into working position, proceed as
follows :
- Pivot side guards (H) under reflector board supports
(A) and lock into place with linch pins (J) (photo 33).
- Pull control cords
(I)
(photo 9 A) accessible from the
tractor cab to unlock cylinders (photo 34) and lower
rotors.
- Attach tine arms to their respective rotors (see page
16).
- Insert handles (K) through hole in lock rods, release
the foldable guards (Z) and lower them in working
position (see arrow, photo 34).
- Return handles (K) in their storage location (C)
(photo 34).
Always maintain the tractor hydrau-
lic valve in the free floating position
during work.
Make sure there is nobody in the
machine operating area before low-
ering the rotors into their working
position.
Make sure that the sliding sections (E)
of the telescoping lift arms (F) slide
freely and have the right amount of
play when folding the machine from
transport to working positions and
vice versa. To adjust play, tighten
bolts (G) until there is no play, then
untighten them half a turn (photo 35).
Tighten lock nuts (I) after adjustment
(photo 35).
NOTE :
To avoid any risk of jamming regularly grease
the sliding parts of the lift arms with SHELL
Multi-Purpose grease NLGI grade 2.
