Orthman 1TRIPR II ROW UNITS Operator's Manual page 69

This table has been created to help understand the
effects that the set bolt and spring tension setting have
on the AR trip linkage's ability to trip. The numbers
shown in the chart represent the estimated amount of
force (lb/kg) that is required to trip the tail when the shank
is at the deepest setting.
As the spring tension is increased (tightened up) and the
set bolt setting is decreased (unscrewed), the force
required to trip is increased.

Orthman Manufacturing encourages the operator to start out
at the factory setting, where the row unit tail will trip very
easily. From that point adjust the set bolt and spring tension
to attain the desired AR trip linkage setting.
The standard version of the 1tRIPr® II without the AR trip
linkage is equipped with a shear bolt. See "Shear Bolt
Protected Tail" on page 5-20. The amount of force it takes to
shear this bolt is slightly over 8000 lb (3629 kg).
*Notice that the chart has values that exceeds 8000 lb
(3629 kg). Orthman Manufacturing recommends using
extreme caution when adjusting the AR trip linkage to a
setting above 8000 lb (3629 kg). Using a setting that exceeds
the 8000 lb (3629 kg) mark is likely to increase the chances
of damaging the shank in the event an obstacle is
encountered.
