Procedures to change the spacing
7)
To close the fertilizer
outlet, place the chutes (I) over
the augers that will not be used.
Retighten all sets, paying attention to the following points:
• Retighten the nuts that fasten the seed rows on the frame gradually,
avoiding to totally tighten each nut at a time.
• That information is also useful between a row unit and another. So,
do not totally tighten a row unit at a time, but gradually.
• When switching between this nut tightening operation of a row unit
and passing to another, it is necessary to spin the hexagonal axle
to keep the proper alignment and avoid locking.
• The tightening of the bearings that fasten the hexagonal axle should
be done in the end.
• Check the correct alignment of the chains (clutches/wheelsets).
IMPORTANT
6)
Loosen the stabilizer bars (G) by removing the bolts (H), brackets, washers and
nuts. The stabilizer bars keep an uniform spacing between the seed rows. The longer bars
are for spacings from 800 to 900 mm.
