Adjustment and Operation
Wheel Placement
Cleaner arms have two alternate mounting holes for
cleaner wheels. Which hole to use depends on your field
conditions, experience and preference. Great Plains
suggests starting with the “more aggressive” positions.
Too aggressive row cleaner use can remove treated soil
from the seed furrow area, reducing effectiveness of
treatments.
Make the placement choice prior to setting row cleaner
depth, as moving the wheel position changes the depth.
When changing placement, be sure to re-adjust the
depth.
Dual Wheel Placement
Offset Dual Wheel
Refer to Figure 15
Start with this “more aggressive” configuration. Mounting
one wheel forward and one wheel retracted allows the
wheels to rotate independently while still keeping one
close to center-line.
It is not possible to set both tines to the same depth in
this configuration. Adjust row cleaner height based on
the tines closer to row unit center-line.
Retracted Dual Wheel
Refer to Figure 16
This setting is the least aggressive. If clogging occurs
with offset, try retracted.
Retracted may also be necessary to shorten the overall
length of the row cleaner, and provided greater clearance
from leading equipment or accessories.
Intersected Dual Wheel
Not Recommended
Refer to Figure 17
In this configuration, the disk tines mesh. This is an
extremely aggressive placement, and is not
recommended by Great Plains, as it causes excess tine
wear and is prone to clogging and rotation stoppages.
