OPERATION AND FIELD SETTINGS
1TRIPR II Row Units OM-EN 5-5
Row Unit Down Pressure Adjustment
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
adjusting row unit down pressure. See “Implement
Inspection” on page 7-4.
CAUTION
!
Be extremely careful working around unshielded sharp
edges. Injury may result from contact with sharp edges.
3. Loosen the jam nuts (2) from the spring plugs (3).
4. Adjust the down pressure adjustment bolts (1).
NOTE: Adjust both down pressure springs (4) evenly.
Turn clockwise (CW) to increase the spring
tension, creating more row unit down pressure.
Turn counterclockwise (CCW) to decrease the
spring tension, reducing the row unit down
pressure.
5. Tighten jam nut against spring plug and torque to
specification. See “Torque Specifications” on
page 7-2.

NOTE: Too much down pressure applied to the individual
row units can essentially lift the toolbar to an
undesireable operating height. Lifting the toolbar
will cause the parallel linkages to “bottom out” and
the row units will not operate independent of the
toolbar, resulting in non-uniform tillage across the
implement.
