Adjustments

To get full performance from your drill, you need an
understanding of all component operations, and many
provide adjustments for optimal field results. Even if
planting conditions rarely change, some adjustment
items need periodic attention due to normal wear.

The 1300 and 1300F have 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.

Planting Depth
Setting nominal planting depth, and achieving it
consistently, 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, and;

• Disk Blade Adjustments (as blades wear).

Seed and Fertilizer Rate
Details are found in the Seed Rate Manual (175-157B).

Materials are applied by fluted feed meters driven by the
left end wheel. Independent mechanisms main seed,
fertilizer and optional small seeds application.
