Terra-Tine™ Adjustments
Refer to Figure 77 through Figure 79
Note: All adjustments must be made with the planter in
the fully raised position.
Equipment Damage Risk:
Be sure to check that the Terra-Tine Row Cleaner tines DO
NOT touch the coulter blade or any other attachments. Such
contacts will cause excess wear to all parts involved. At least
1 ⁄
2
in (13mm) clearance is recommended.
1. When the blade is out of the soil, adjust the
Terra-Tine lock collar
height to set the height of
tine fingers flush with the bottom of coulter blade.
2. For side-to-side alignment, rotate the shank mount
around the vertical shaft
and retighten the square
head set screw (set screws not visible in twin-row
illustration).
3. If tines are found to be rolling over, rather than
moving trash, spring tension
can be increased.
See the Terra-Tine manual for details.
Using Terra-Tines with Coulters
Refer to Figure 77 and Figure 78
Tines may be set ahead
of, behind , and to the
right or left of frame-mounted coulters.
4. Fore-to-aft adjustment is accomplished by adding or
removing the extension arm
to place the
Terra-Tine Row Cleaner 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.
