Terra-Tine™ Row Cleaners
Refer to Figure 40
These row cleaners are available for:
• direct shank mounting on the front tool bar,
• sharing a Vantage I coulter shank, or;
• unit-mount on the 30 Series row unit.
See page 89 for ordering information.
Terra-Tine™s have three adjustments:
1. Height: Shank-mounted Terra-Tine™s adjust at the
tube clamps
. Unit-mounted Terra-Tine™s adjust
at the bracket mounting holes.
When the blade is out of the soil, adjust the Terra-Tine™
to set the height of tine fingers flush with the bottom of
coulter blade or opener disk.
Refer to Figure 40
2.
Terra-Tine™s are adjustable for leading ( , )
trailing ( , ), and left ( , ) or right offset ( , ).
Fore-to-aft adjustment is accomplished by adding or
removing an extension arm to place the Terra-Tine™ to
either side of the coulter hub depending on the desired
position or clearance between other attachments.
Testing has shown better performance behind the hub,
but available space may dictate the mounting position.
Refer to Figure 42
3. Tension: If tines are found to be rolling over, rather
than moving trash, spring tension can be increased.
Adjust spring tension by removing a bolt
and
pivoting the adjuster relative to the pivot mount.
There are five possible orientations:
Equipment Damage Risk:

DO NOT touch the coulter blade or other attachments.
