C) Closing seeds outlet to block operation at alternate
seeding rows:
• Be sure to cover the seeds outlets which correspond to
the seeding rows you want to block for operation
(Picture
15-A) .
• Remember to remove the star at the ejecting system
from the blocked outlets.
• The fertilizer box outlets matching the blocked seeds
outlets must also be closed
(Picture 16-A).
To block row units, proceed as follows: the row units,
which are not going to be used, will be lifted onto a espe-
cially designed plate for the machine
(Picture 17-A).
Keep the machine on even, steady ground and proceed
as follows:
a) Set the springs in all units in the position with the least
down pressure (backwards).
b) Lift front coulters to top.
c) Thread lifting hydraulic cylinders stop-ends fully.
d) Lower planter completely (till cylinders stop-ends).
e) Place the especial plate between the upper parallel
arm and the supporting arm of the unit that will be kept in
raised position.
