Note: All adjustments must be made with the applicator in

the fully raised position.

Refer to Figure 58

Excess Wear Risk:
Check that the Terra-Tine™ Row Cleaner tines DO NOT touch

When the blade is out of the soil, adjust the lock
collar height to set the height of tine fingers flush with
the bottom of coulter blade.

Side-to-side alignment can be done by rotating the
shank mount around the vertical shaft and
retightening the square head set screw.

distance of 5.4 in. (13.7 cm) from frame bottom to

the frame clamp. Changing arm angle

also

changes tine height.

(pivot mount hole closest to Terra-Tine™ mount).

Note: All adjustments must be made with the applicator in

the fully raised position.
