Down Pressure Charts
Row Unit Adjustments
Down Pressure
Springs provide the down pressure necessary for
row unit disks to open a seed trench. The springs
allow the row unit to float down into depressions
and up over obstructions.
You can adjust down pressure individually for
each row unit. Use only enough down pressure to
cut the seed trench and maintain proper soil-firm-
ing over seed. Excessive down pressure will lead
to premature wear on row-unit components.
Refer to Figure 19
To adjust, lift T-handle:
• Move T-handle back to increase spring pres-
sure.
• Move T-handle ahead toward tractor to de-
crease spring pressure.
Refer to the Down Pressure Charts on the right
for the amount of spring pressure at the row unit
for each spring setting.
