DOWN FORCE SETTINGS
The spring has been factory pre-set at 8.5" (21 cm) but can be adjusted from 8" - 9" (20 - 23 cm) as desired to fit soil
conditions.
Position 2 is ideal for conventional tillage and softer soil conditions. Position 3 is used for no-till and harder soil
conditions. Refer to the chart above to adjust for specific conditions.
In positions 1 and 2, coulter height can be further adjusted manually if needed by loosening the main bolt jam nut and
the main bolt, up to 10 turns or 1" (2.5 cm) length.
NOTE: Approximately ¼" of bolt length adjustment provides nearly 1" (2.5 cm) of coulter height change.
