ADJUSTMENTS
6.18.1 REPLACING THE FERTILIZER’S TRANSMISSION
For a wider range of adjustments, cogs A and B are inter-
changeable. The previous table shows both possible type
of transmissions P.S= 20Z P.E= 35Z or P. S =35Z P. E =20Z .
To change the transmission ratio:
1- Remove the lid’s securing screws (1, Fig. 6.120).
2- Loosen the chain. For this purpose, use a wrench to ope-
rate on the tensioner’s nut (2, g. 6.121). To make this
operation easier, hold the tensioner’s screw (3, Fig. 6.121)
using a dierent wrench (Fig. 6.122).
3- Remove the securing allen screws from the pinions (4,
Fig. 6.121).
4- Remove the pinions
and interchange
their position.
5- Fix the pinions
using the screws (4,
Fig. 6.121).
6- Place the tensioner
at the suitable posi-
tion and x it using
the nut. For this
operation, hold the
screw using a die-
rent wrench (Fig. 6.122).
7- Place the lid back and x it using the screws (1, Fig. 6.120)
