ROW UNIT DOWN PRESSURE
AVOID CRUSHING. Make sure all personnel are clear of the implement. Lower implement
to the ground, place tractor in park, turn off engine, and remove key.
USE BAR STANDS TO SUPPORT THE IMPLEMENT. Park implement on a clean, dry,
and level surface. An uneven surface could cause implement to shift or fall, resulting in
personal injury or death, as well as implement damage. Securely support all implement
components that must be raised. Remove buildup of grease, oil, or debris prior to
adjusting.
Four adjustable down pressure springs supply row unit down pressure to assist with row
unit tooling soil penetration. After toolbar height and orientation is set
(pg. 5 - 1, 5 - 2)
row
unit down pressure can be adjusted.
Down pressure springs should be adjusted so that parallel linkages operate independent
of the toolbar and the toolbar serves as a towing device. Compacted soil conditions may
require an increase in down pressure and softer soil conditions may require a decrease in
down pressure to provide adequate soil penetration across the implement.
If a rigid toolbar is used with the
1tRIPr®
row units, down pressure adjustment between
row units typically varies slightly. If a folding or stacking toolbar is used, wing sections
tend to float upward, unless mechanically restrained.
(refer to toolbar operator’s manual)
Wing row units, not mechanically restrained, may require a decreased amount of down
pressure to allow row units to perform consistently across the implement.
NOTE: Recommended tools: Down Pressure Adjustment Bolt and Jam Nut - 3/4 end
wrench, Spring Plug - 1 1/4 end wrench.
NOTE: Adjust all four down pressure springs per row unit evenly.
1. Loosen jam nut from spring plug.
2. Adjust down pressure adjustment bolt.
(clockwise - increase pressure, counterclockwise - decrease pressure)
3. Tighten jam nut against spring plug to torque specifications.
(pg. 8 - 4)
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.
