Step 5. Fit all primary and secondary
hoses. Ensure that there are no
sharp turns and that the hoses stay
as level as possible.
A level and smooth fitting of
hoses will help prevent blockages
from occurring, and extend the life
of the hose.
Use the large plastic ties to prevent
hoses from sagging or wearing on moving
parts.
IMPORTANT
Tertiary hoses when fitted to the
secondary heads must fall at a minimum of
10 to 15° angle. The hose fall must be
constant and increase as it approaches the
sowing boot. Blockages will occur if the
tertiary hoses rise or lay flat when leaving
the secondary heads.
Fig.A16 Typical fall on tertiary hose.
When choosing a secondary head
port to attach the tertiary hose, the installer
should ensure that the hose can rotate if a
tine jumps (refer Fig A17 & A18). If the
hose movement is restricted the tertiary
hose will kink.
Tertiary hoses that carry across a
wing-fold zone must also be curved to allow
for rotation.

Head Blockage Junction Box
The standard Head Blockage sensor
is supplied with a junction box to join the
relevant wires. It is possible to mount the
junction box onto the secondary head
support bracket using cable ties (refer
Fig.19).
