OPERATION
Packing and Trip Pressure Tips:
x It may be desirable to further increase packing and trip pressure in drier,
sandier soils.
x Higher packing and trip pressures can result in more rocks being pulled
out of the soil.
x Higher wear on opener parts may be experienced with higher pressure.
x Soil packing will be more firm with higher packing and trip pressure.
x A reduction in shank tripping action will be experienced in firmer soil
conditions.
