PREPARATION AND SETUP
1TRIPR II Row Units OM-EN 4-17
Automatic Reset (AR) Trip Linkage
Installation
One of the most innovative Orthman 1tRIPr® II Row Unit
accessories is the automatic reset (AR) trip linkage. This
allows the row unit to be tripped by underground
obstructions and then automatically reset. This feature
helps protect the shank and wavy coulter tooling. The
AR trip linkage will be installed on your 1tRIPr® II
machine from the factory if ordered with that option.
DANGER
!
Avoid crushing. Failure to follow this information will
result in death or serious injury. Make sure all personnel
are clear of the implement before lowering.
DANGER
!
Avoid crushing. An uneven surface could cause the
implement to shift or fall, resulting in injury or death as
well as implement damage. Park the implement on a
clean, dry, level surface.
DANGER
!
Avoid crushing. Failure to follow this information will
result in death or serious injury. Use bar stands and
cylinder stops to support the implement.
1. Lower the implement to the ground, place the tractor
in park, turn off the engine, and remove the key.
2. Remove buildup of grease, oil, and debris prior to
installing row unit mounts. See “Implement
Inspection” on page 7-4.
NOTES:
• It may be easier to manipulate the tail section of the
row unit with the tillage shank in a raised position.
• It may be desirable to have the 1tRIPr® II machine
lifted up with a tractor so there is no pressure on the
tail section of the row units.
• If machine is not hooked to a tractor, it is important
to only remove one row unit at a time. Fully complete
the installation of one AR linkage before starting on
the next row unit, as the tail sections of the row units
keep the machine from tipping over backwards.
DANGER
!
Avoid crushing. Failure to follow this information will
result in death or serious injury. Use an appropriate
lifting device to support the tail section.
CAUTION
!
Avoid injury. Springs are under tension. Adjust spring
tension slowly. Verify tension is loose before removing
springs. Failure to follow this information will result in
serious injury.
3. Loosen spring tension. See “Automatic Reset (AR)
Trip Linkage” on page 5-21.
4. Remove bolts (1), jam nuts (2), and left
down-pressure spring (3).
5. Remove bolt (5) and pin (4).
6. Remove spring pin (8), pin (7), and shear bolt
assembly (6).
