The 1tRIPr® II Row Unit tail shear bolt is designed to
protect the shank and other tail tooling from damage by
shearing when a rock (5) or other obstacle is hit
underground. This method is only meant for occasional
tripping but is not effective in rocky conditions.
When the encounters an immovable object, the resulting
force will shear the upper bolt, and the tail will rotate
upward about the lower pivot pin to clear the obstacle.
NOTE: If the shear bolt is damaged, the operator should
stop and replace the bolt. Orthman recommends
using a grade 5 bolt for replacement. Higher or
lower grade bolts may result in poor performance
and cause damage to the implement.
CAUTION
!
Be careful to not over-tighten the shear bolt. This could
exert a clamping load on the trip plate that will add
resistance to the tail's ability to trip.
When installing the shear bolt, tighten it to the point
where the nut will flatten a lock washer. If the bolt is
tightened correctly, the tail should not be loose but will
not have an excessive clamping load.
