Spring Tine Harrow
Harrow Tine Angle
Refer to Figure 21
The drawing on the right shows a successful har-
row position for no-till and minimum-till conditions.
Because of different soil moisture, trash levels
and trash types, you may need to reposition the
tube frame or tines. Initially position the frame and
tines as shown, then readjust as necessary.
Harrow Frame and Tine Adjustment
Refer to Figure 22
To adjust harrow frame loosen the four hex nuts
(1) on the u-bolts and rotate frame tube (2) as
necessary.
To adjust tines, loosen the four 1/2-inch hex nuts
(3) on the 1/2-inch u-bolts (4) on the support bar
(5). Rotate tine tubes (6) so tines (7) are against
stop bushings (8) and are angled back as neces-
sary. Retighten hex nuts on u-bolts.
Harrow Chain
Refer to Figure 23
In clean, tilled, extremely loose soils, harrow chain
may need to be shortened to lift harrow off the
ground.
To adjust chain, support the harrow to remove
weight from the harrow arms. Remove the lower
bolt and select a different chain link.
Note: Keep the harrow arms at the same length.
