Frame Weight
In challenging no-till conditions, some row-unit
down-pressure settings (across all rows), and many
frame-mounted coulter settings, may be high enough to
lift the wing caster wheels off the ground. To avoid
inconsistent results, add weight to the wings.
One or two pairs of (four total) weight brackets are
optional. The weights required are common “suitcase”
tractor weights, and are widely available, although not
supplied by Great Plains.
Each bracket accepts up to five standard weights, about
500 lbs (227 kg) per wing, or 1000 lbs (454 kg) per kit.
Great Plains recommends loading no more than two sets
of brackets, representing 2000 lbs (907 kg) total.
Do not add weight to the center section. It is always
heavier than even a fully weighted wing, and never
requires additional weights.
Available Down Force
Each Weight set assumed to be fully populated with five
100 pound weights.
Note: This table does not include the effect of adding
frame-mounted coulters to the drill.
Although frame-mounted coulters add 61 lbs (28
kg) to each row, they also rely on the available
weight per row, and can easily require more weight
than they contribute.
Although this reduces the weight available to the
openers, the opener workload is also reduced by
having the furrow prepared by the coulters.
