Adjustments
To get full performance from your drill, you need an
understanding of all component operations, and many
provide adjustments for optimal field results.
The 2S-2600HD has double-disk openers with
depth-controlling press wheels mounted on floating
opener frames. Opener bodies are staggered for easy
soil flow. All openers pivot on a common axis to maintain
consistent depth as the opener frames follow contours. A
spring provides the down pressure necessary for opener
double disks to open a seed furrow. The spring allows
openers to float down into depressions and up over
obstructions. Individual openers can be adjusted to
account for tire tracks.
Even if your planting conditions rarely change, some of
these adjustment items need periodic attention due to
normal wear.
Seed and Fertilizer Rate
Materials are applied by fluted feed meters driven by the
gauge wheels. Independent mechanisms control seed
and fertilizer application. Optional Small Seeds rate is
controlled entirely by Rate Handles.
Main Box Seed rate is controlled by adjustments for:
• Drive Type sprocket (one sprocket each gauge wheel)
• Seed Rate Handle (one handle each seed box)
• Feed Cup Door (one each seed tube)
Fertilizer rate is controlled by:
• Range sprockets (one set each fertilizer box)
• Final Driver/Driven sprockets (one set each box)
Planting Depth
Setting nominal planting depth, and achieving it consis-
tently, is affected by multiple adjustable drill functions,
from greatest to least effect they are:
• Opener Depth (Press Wheel Height)
• Opener Frame Down-Force,
• Row Unit Down Pressure (Spring),
• Opener Height,
• Opener-Subframe Adjustment,
• Frame Weight (at higher pressures), and;
• Disk Blade Adjustments (as blades wear).
