Changes to the hydraulic cylinder mainly effect the drill depth, but also the opener disc pressure and the
pressure rollers. Changes to the opener disc pressure adjustment mainly effect opener discs and
pressure rollers, but also have an influence on the drill depth.
SAFETY WARNING
With each alteration one must therefore check the drill depth and the effect of the pressure rollers
on consolidation and depth guidance.
Depth Setting
It is highly recommended to find the desired setting by trying and testing.
• Turn the opener disc pressure adjustment back to a low pressure.
• Insert the same quantity and color combination of aluminum clips on the hydraulic cylinders.
• Lower the machine in operating position on the aluminum clips and drive a few yards in the field. The
cylinders must always be fully extended - watch the pressure gauge.
• Check the coulter seed depth and the consolidation by the press wheels.
• If necessary increase the opener pressure and check for changes after driving a few yards in the
field again.
If the desired adjustment cannot be found within the pressure adjustment range, the process must be
repeated using the next lower setting on the hydraulic cylinder, until the correct setting is found.
In working position the opener assembly unit arm should be aligned in horizontal position.
