6. Assembly of rotors, caster wheels and
secondary PTO shafts
Assemble both right and left-hand rotors to pivoting pins
(L) of lift arms (M) so that the undercarriages (N) are
located in front of the rotor’s vertical axles (H) (seen in the
forward direction) (see figure 24). Secure the rotors with
retaining rings (T) (dia. 45 x 2.5) (photo 10). Do not forget
to install thrust washers (Y) (dia. 45 x 55 x 3) between
retaining rings (T) and plate (X) (photo 10).
Connect flexible hose (H) (photo 7) to the tractor hydraulic
outlet and slightly raise the rotors off the ground.
Slide the cylindrical hub protectors (01) onto axles (N)
until they seat on the axles' shoulders (fig. 11). Then slide
the conical grey protectors (02) onto the axles with the
conical side facing the wheel bearing locations (fig.
11).The grey protecting plugs are seated tightly on the
spindle’s shoulders. Drive them in place using a driver and
apply a blow with a hammer. Fill wheel caps (Q) with
grease. Also grease the space between both bearings
located inside the rims.
Install the 4 wheels (L) on axles (N). Insert conical spring
washer (O) (convex side against nut) and fit low self
locking nut (P) (M 16 x 1.5). Tighten to 12 daNm / 88 ft.lbs.
Fit wheel caps (Q) in place (figure 11).
Note : GA 7301 USA are equipped as standard with
bogie axles. To install them, refer to page 27.
Mount cone guard (R) on the rotor side, using clamp
collars and cone guards (R 1) on the bevel gearbox side
using 2 hexagon screws (M 8 x 16) and 2 flat washers
(diameter 9 x 22 x 1,5) (photo 12).
Mount secondary PTO shafts (S) positioning the torque
limiter on the rotor side and the CV joint on the bevel
gearbox side. Before connecting the PTO shafts, it is
necessary to position the rotors so that tine arms operate
symetrically in relation to one another. Connect safety
chains (U and U1) as shown on photo 12.
7. Assembly of reflector boards
Mount the left and the right reflector supports (A) on both
sides of the frame (P) using 4 hexagon screws (C)
(M12x70), 4 flat washers (diameter 13 x 35 x 5) and 4 self-
locking nuts (M12) (Torque 10 daNm / 75 ft-lbs) (photo 13),
in such a way that the side guards (H) can be folded back
in transport position (see photo 43 on page 25).
Fix reflector boards (D) onto supports (A) using 6 hexagon
screws (H) (M 10 x 25) and 6 self locking nuts (photo 13).
Stick the 2 white reflectors (V) on the lower outside
corners of the front reflector boards (D) (see photo 15).
Fit rear reflector board holders (A') to wheel legs (S) with
4 hexagon bolts (C’) (M12 x 70), 4 flat washers (diameter
13 x 35 x 5) and 4 self-locking nuts (M12). Tighten to 10
daN.m/75 ft.lbs (photo 14).
Now assemble rear reflector boards (D’) to the plates (B)
and to their holders (A’) with 4 hexagonal bolts (F)
(M 10 x 25), 8 hexagonal bolts (E) (M 10 x 60) and 12 self-
locking nuts (M 10) as shown in photo 14.
