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 1510HDF, 2010HDF & 2510HDF have double-disk
parallel-arm openers with depth-controlling press
wheels. This system provides accurate depth control and
seed placement over uneven terrain.
Each opener is mounted on a floating opener frame, held
parallel to the ground. Opener bodies are staggered for
easy soil flow. A spring provides the down pressure nec-
essary 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.
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:
• Leveling the Drill
• Opener Depth (Press Wheel Height)
• Row Unit Down Pressure,
• Optional Accessory Hitch settings and Coulter Setup,
• Unit-Mounted Coulter Depth Adjustment,
• Disk Blade Adjustments (as row unit blades wear).
