PLANTER METERING UNIT NG PLUS 2
The NG Plus 2 metering unit in fig. 40 is
shown with standard features. Other options
are available for specific conditions or uses.
The drive chain is mounted as per fig. 41.
The individual disengaging of a metering unit
is possible by removing the lynch pin (rep.1)
of by disconnecting the vacuum hose.
The seed depth is adjusted by the
handwheel (rep.2) which changes the height
of the 2 depth wheels (rep.3) in relation to
the furrow disc openers (rep.4). A sticker
close to the handwheel, provided with a
gradual scale, ensures the uniformity of the
depth control on all row units of the planter.
The furrow opener and ground adjustment
system guarantees an accurate and regular
seed depth in all types of soil and conditions
because the depth wheels are positioned
perpendicular to the falling point of seeds.
The two rear press wheels (rep.5) affect only
the closing of the seed furrow. They float
independently and therefore do not have any
effect on the ground engaging. Their soil
pressure is regulated by the handwheel
(rep.6). This pressure has to be chosen
carefully in order to assure proper seed to
soil contact. Soil should be pressed over the
complete length of the row. This setting
depends on the type and humidity of the soil.
In order for the furrow disc opener to remain
properly cleaned, the 2 gauge wheels (rep.3)
have to touch (without pinching their outside
circumference). After starting up the planter,
the factory assembly may need
readjustment.
Adjust gauge wheel spacing by putting the
washers (rep.7) from one side of the
articulating arms to the other.
Adjust the pressure of the scrapers of discs
by tightening or loosening the bolts (rep.8).
Before and during each new planting
season, check if the seed tubes (rep.9) are
in good condition as consistent and regular
seeding will depend on this. Do not hesitate
to replace them if they are worn or damaged.
To replace them, remove pin (rep.10) after
removing the gauge wheel and furrow disc
opener on one side (Fig.42).
The function of clod removers (rep.11) is to
clear the surface of the soil but not to plow a
furrow. One use of the front brace of the clod
remover is to slice open hard soil and move
stones away from the track of the disc
opener. They need to be adjusted
accordingly. Using them in stony soils may
be a problem because they can cause
clogging and blocking. In this case it is better
to choose an assembly with a flexible
support bracket (fig. 43) which is efficient in
difficult soil conditions.
