Spring Tine Harrow
Refer to Figure 31
Harrow Tine Angle
This shows a successful harrow 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 Figure32
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 necessary. Tighten hex nuts on
U-bolts.
Harrow Chain
In clean, tilled, extremely loose soils, harrow chain may
need to be shortened to lift harrow off the ground.
