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 Model 3S-5000/F/HD/HDF has double-disc 00 or
00HD 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 frames follow contours. A spring provides the
down pressure necessary for opener double discs 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
left end wheel. Independent mechanisms drive main
seed, fertilizer and optional small seeds application.
Main Box Seed rate is controlled by adjustments for:
• Drive Type gearbox lever
• Seed Rate Handle at box (drill front)
• Feed Cup Door (one each seed tube)
Fertilizer rate is controlled by:
• Rate Adjuster at box (drill rear)
Small Seeds rate is controlled by:
• Rate Handle 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:
• 00 & 00HD Series Opener Depth,
• Hydraulic Down Pressure All Openers,
• Row Unit Down Pressure (Spring),
• Opener Height, and;
• 00 Row Unit Adjustments (as blades wear).
