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 3P1006NT has double-disc 06 Series 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 frame follows contours. A
spring provides the down pressure necessary for double
discs to open a seed furrow. The spring allows openers
to float into depressions and 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
Seed are applied by fluted feed meters driven by the
ground wheels. Independent mechanisms drive main
seed, fertilizer, native grass and small seeds application.
Main Box Seed rate is controlled by adjustments for:
• Left Drive Type gearbox lever
• Seed Rate Handle at box (drill front)
• Feed Cup Door (one each seed tube)
Dual Box Seed rate is controlled by adjustments for:
• Right Drive Type gearbox lever
• Seed Rate Handle at box (drill rear)
• Feed Cup Door (one each seed tube)
Native Grass rate is controlled by:
• Rate Reduction Sprockets (see manual 202-583M)
• Right Drive Type gearbox lever (drill front)
• Driven Sprocket at Native Grass Seed box
Small Seeds rate is controlled by a Rate Handle at box
(drill rear)
Fertilizer rate is controlled by a Rate Adjuster at box
(drill rear)
Planting Depth
Setting nominal planting depth, and achieving it
consistently, is affected by multiple adjustable drill
functions, from greatest to least effect they are:
• Coulter Height
• Opener Depth (Press Wheel Height)
• Opener Down Pressure, and;
• Disc Blade Adjustments (as blades wear).
