OPTIONAL ACCESSORIES
1) 3-POINT FRAME EXTENSION
(Kit No 114 6230)
(photo 26)
For tractors with limited linkage possibilities, two
extensions (R) can be fitted to the 3-point frame (C),
enabling the machine to be lifted higher during
transport.
2) DUPLEX REDUCTION GEARBOX (Kit No 111 6440)
A «Duplex» reduction gearbox for the
GF 5001 MHA
can be supplied as an optional extra when using the
machine for raking night swaths. With this gearbox, the high rotor speed
(rotational frequency)
necessary for
tedding and turning is maintained and there is also a lower rotor speed
(rotational frequency)
for raking night
swaths.
The reduction gearbox can be attached to existing
GF 5001 MHA
s without modification. To install the «Duplex»
reduction gearbox proceed as follows :
- Fit guard (G) (photo 28) on Duplex reduction gear-
box, using the hardware provided therefore.
- Remove original PTO shaft guard from the central
gearbox.
- Slide the Duplex reduction gearbox unit (Q) on the
drive shaft from the central gearbox (R) and secure
in place with 2 self-locking screws (S) (M 12 x 40)
and 2 spring washers (torque : 9 daNm - 65 ft/lbs).
- Fit the retaining ring (35 E) delivered with the kit on
the drive shaft from the central gearbox.
When tedding, the PTO shaft must be fitted directly
to the splined end of drive shaft. When raking night
swaths, mount the PTO shaft on the «Duplex» reduc-
tion gearbox input shaft (photo 28). In this case the
tractor PTO speed
(rotational frequency)
should be
maintained at 400 rpm
(min
-1
)
and ground speed
between 5-7 km/h (3-4 miles/h). Mount the PTO shaft
cover (E) inside the guard (G) using wing nut (H) so
that the PTO end not in use is fully guarded (photo
28).
