6.8 Adjusting The Center Section
This adjustment will affect the suspension (trapeze function) and must
therefore be done properly to optimize the EAGLE 3 Point Boom perfor-
mance.
IMPORTANT: Lubricate pivot linkage and grease skid plates prior to
adjustment .
1. Ensure that the sprayer
is on level ground.
2. Tighten the four adjust-
ment bolts (A)(Fig.19)
approx. 1/2 turn.
3. Grasp the wing by the
end and lift it approx. 20
in.(490mm). Release
the wing and it should
smoothly return to
approximately the
horizontal position.
4. If the trapeze will not let
the boom go back to horizontal position, the bolts must be loosened
again. The spray boom is properly adjusted when it returns to the
horizontal position under its own weight.
6.9 Adjusting the Boom Transport Position
1. Lift the boom all the way to the top.
2. Fold the boom into the transport position. With the fold cylinder
pressurized, determine if the boom sections need to be adjusted
inwards or outwards.
Note: Ensure that the boom wings will not interfere with the tractors
wheels or structure.
3. Relieve the pressure from the fold cylinder by unfolding the
boom a few inches.
4. If the boom comes too far in towards the tractor cab,
loosen the nut (B)(Fig.20) and adjust collar
(A)(Fig.20) in towards the cylinder housing.
5. If the boom goes too far out away from the
tractor cab, adjust the collar (A)(Fig.20)
away from the cylinder housing.
6. Secure the jam nut (B)(Fig.20).
7. Pressurize cylinder to see if the boom is properly adjusted. If not,
repeat the above procedure until it is correctly adjusted.
