Check Tires, Blades & Mounts
Always inflate tires to factory specifications before mak-
ing any of these adjustments.
Prior to first use, check coulter mounts to ensure that
coulters are at the correct nominal height. Periodically re-
check disk blades. As blades wear, the coulters will not
cut as deep.
Refer to Figure 12
With the drill raised, the distance
from the bottom of
the tool bar to the bottom of the pivot casting is:
28.26mm (11.13in).
To adjust one or more coulters, see “Coulter Adjust-
ments” on page 71.
Check that packer wheels are not hitting their bottom
stop pins. See page 28 for adjustment.
Periodically check the opener disk blades. As blade
wear, the furrow will not be as deep. Adjust the T-handle
setting to maintain a constant seeding depth. See
“Opener Depth (Press Wheel Height)” on page 93.
In addition, worn blades will not have correct contact.
See “Disk Blade Adjustments” on page 91 for blade
contact adjustments.
Disable Seeding & Weight Drill
Disable Seeding
To avoid unnecessary wear on the drive system during
setup, disengage the main drive clutch (see See “Main
Box Drive Clutch” on page 77), and on V300F, disen-
gage the fertilizer clutch (page 86).
If using seed for test weight in the main seed box or fertil-
izer box, it is important to prevent it from being metered,
(or leaking through the meters, which can happen even if
the shafts do not turn). Set the main box seed rate han-
dle to 0. On model V300F, also set the fertilizer rate
adjuster to 0.
Adjust at Half Material Weight
To properly set depths and down-pressures, the drill
needs to weigh approximately what it will weigh halfway
through a planting session. This can be done with mate-
rial in the seed/fertilizer boxes, or by using extra weights.
However, if the planting is with the Small Seeds box, the
weight is low enough that no simulation is necessary.
If you will not be using extra weights on the drill when
planting, but have “suitcase” weights available, material
weight can be simulated with weights on the weight
brackets. Note that fully loading both brackets may still
be significantly less than half a full material load.
