OPERATION
INDEPENDENT BERM BUILDERS - DOWN PRESSURE
Down pressure can be increased or decreased based on conditions. For heavy residue or compacted
soil, typically, more down pressure is needed.
To increase down pressure on the berm building discs, tighten the 3/4” nylon lock nut on the IBB arm
compression spring. To decrease pressure, loosen nut. This adjustment can be checked by measuring
the distance from the spring mount place to the top of the spring cap. The factory setting is approximately
7.25” and can be adjusted from 6” to 7.5”
