OPERATION AND FIELD SETTINGS

The AR trip linkage comes set from the factory to trip
easily, and will need to be adjusted to adapt to the
specific operating conditions. It is important that the user
understand how the AR trip linkage works and the results
of the different adjustments.
Figure 5-17 identifies the important geometry points and
adjustment locations. Without the AR trip linkage, the tail
would be free to rotate about the pivot pin (7). The
linkage installed keeps the tail from rotating about the
pivot pin by creating a brace between point A and
point B. That brace is made of two links (8) and ability to
rotate in the middle at point C.
When the shank encounters an immovable object, the
resulting force will rotate the linkage at point C, allowing
the tail to rotate upward about the pivot pin until the
obstacle is cleared. The upward rotation of the tail and
the rotation of the linkage causes the four reset springs to
stretch. The force stored in the stretched springs
provides the power necessary to rotate the tail
downward, which in turn drives the shank back into the
ground and snaps the linkage back into place.
If you visualize a straight line between point A and point
B, the distance that point C is away from that straight line
directly affects how difficult it is to buckle the trip linkage.
NOTE: The closer point C is to that line, the more difficult
it is to trip. The further away point C is from that
line, the easier it is to trip.
CAUTION
!
Avoid injury. Springs are under tension. Adjust spring
tension slowly. Failure to follow this information will
result in serious injury.
The AR trip linkage comes set from the factory to trip
easily. Operators can adjust this setting by loosening the
jam nut (15) and adjusting the set bolt (16). One full turn
of this set bolt represents about 1/8 in (0.32 cm). The set
bolt setting (17) is measured from the stop block (13) to
the rear trip link (14). See Figure 5-18 on page 5-23.
NOTE: It may only be necessary to move the set bolt
1/8 in (0.32 cm) to 1/4 in (0.64 cm) to achieve the
correct offset distance for the soil and desired
tripping operation.
The preset tension in the four reset springs will affect two
things: the amount of force available to drive the shank
back into the ground from the tripped position, and the
amount of force required to trip the linkage. A higher
spring tension will increase both of these.
The factory setting of the spring tension setting (9) is set
to be 2 in (5.1 cm). This measurement may vary slightly
due to differences in spring cut lengths and spring plug
castings.
Spring tension adjustments can be made on either side of
the four springs, with each spring adjusted equally. To
adjust the spring tension, loosen the jam nuts (11) that
are up tight against the spring plugs (10). While holding
the spring from rotating, adjust the bolts (12) as desired.
Tighten the jam nuts (11) to prevent the springs from
coming loose.
