Dual Terra-Tine™ Adjustment (Option)

Terra-Tine™ row cleaners are aligned on the center-line
of the center opener of each triple row set.

With the implement raised, tine height (at the bottom of
the tines) is normally set to the same height as the lower
edge of the coulter blade (or about 6 mm above opener
depth).

There are three adjustments for these row cleaners:

Excess Wear Risk:
Check that the Terra-Tine™ row cleaner tines DO NOT touch
any other implement components. At least 13 mm clearance is
recommended. Tine contact causes excess wear to all parts
involved.

Note: All adjustments must be made with the implement

in the fully raised position.

Terra-Tine™ Down Force

Refer to Figure 40
A series of three holes in the spring adjuster

and pivot

mount plate

provide five combinations for different

levels of spring tension. The following table shows the
down-force levels available.

Note: Changing force also changes height.

Terra-Tine™ Height

Refer to Figure 39
Adjust down-force before adjusting height. To adjust
height, loosen both set screws

. Slide mount up or

down shank. Check row alignment. Tighten set screws.

Terra-Tine™ Row Alignment
The lateral position of the Terra-Tine™ may be changed
by loosening the offset shank set screws

(and height

set screws

) and/or the tool bar mount bolts

.
