Adjustments
To get full performance from your lister / cultivator, you
need an understanding of all component operations, and
many provide adjustments for optimal field results.
The Model LC40 has straight-blade depth-band coulters
mounted on floating opener frames. Dual springs provide
the down pressure necessary to hold the row tools at the
height set. Individual openers can be adjusted to account
for tire tracks.
Lister configurations include a height-adjustable shovel,
and adjustable furrower discs.
Cultivator configurations include a height-adjustable
shank, width-adjustable soil deflectors, and optional
barring-off discs.
Plowing/Cultivating Depth
Setting nominal depth, and achieving it consistently, is
affected by multiple adjustable implement functions, from
greatest to least effect they are:
• Lister Shovel or Cultivator Height,
• Coulter Depth,
• Implement Tool Bar Height (hitch set), and;
• Row Unit Down-Force.
