OPTIONAL EQUIPMENT
1) 3-POINT FRAME EXTENSION
(Kit No 114 6230) (photo 28)
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 trans-
port.
2) DUPLEX REDUCTION GEARBOX (Kit No 111 6440)
A «Duplex» reduction gearbox for the GF 5001 MH 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 MH’s without modification. To install the «Duplex»
reduction gearbox proceed as follows :
- Fit guard (G) (photo 30) on Duplex reduction gearbox,
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 conical spring washers (photo 29) (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 30). 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 30).
