Frame Weights
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 gauge wheels off the ground. To avoid
inconsistent results, add weight to the wings.
Two pairs of (four total) weight brackets are standard.
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.
An optional third bracket kit is available (see “Dual
Weight Kit” on page 73). The kit includes a pair of
brackets (one for each wing). The kit does not include
weights.
If an additional weight kit is required, have your dealer
contact the factory for special instructions.
Great Plains recommends loading no more than three
sets of brackets, representing 3000 lbs (1361 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.
