Disk Scraper Adjustment
Refer To Figure 22
To keep opener disks turning freely, dirt scrapers are
mounted between disks to clean as the disks rotate. As
field conditions vary, you may need to adjust the
scrapers.
To adjust, loosen 3/8-inch bolt and raise or lower scraper
as needed.
Harrow Adjustment
Refer to Figure 23
Figure 19 shows a successful harrow position for no-till
conditions. Because of different soil moisture, trash lev-
els and trash types, you may need to reposition the tube
frame or tines. Initially position the frame and tines as
shown in , then readjust as necessary.
Refer to Figure 24
To adjust the frame, loosen the four hex nuts (1) on the u-
bolts and rotate the frame tube (2) as necessary.
To adjust the tines, refer to . 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 the tines (7) are against the stop
bushings (8) and are angled back as necessary. Re-tight-
en hex nuts on u-bolts.
Leaf Spring Adjustment
Refer to Figure 25
A leaf spring is located just ahead of the vertical pivot.
Pre-emergence Marker Adjustment The spring is de-
signed to provide just enough force to keep the hitch
square and stable for turning at field ends and to add sta-
bility for drilling in rough field conditions. Proper leaf-
spring adjustment is important for smooth implement
operation.
To adjust properly, square tongue with transport frame
and adjust 3/8-inch u-bolts (1) on each side until leaf-
spring rollers (2) just make contact with roller pads (3) on
transport frame. Make sure both right and left sides are
adjusted properly.
