73 Maintenance and Lubrication
HD 10 Series and 25 Series Disk Spreaders and
Scrapers
NOTE: It is normal for blade spreader to have some
looseness in the holder and between the blades.
Some looseness is required for proper operation.
Refer to Figure 103
1.
Remove side gauge wheels from arms to access
opener disks and scrapers.
2. With unit raised, check blade spreader (1) for wear.
Replace spreader if it is 1/2 inches wide or narrower.
To replace, remove disk blade (3). Drive out roll pins
(2) and install new spreader.
3. When reinstalling disk blades, put two shims (4) be-
tween bearing and shank on each blade. Tighten
bolts.
NOTE: You may need fewer washers on worn disks.
4. Check that outside disk scrapers (5) are formed to disk
blades to help remove any mud. Bend and twist scrap-
ers to fit blades as necessary. After every 200 acres of
operation, check outside scrapers for proper adjust-
ment and wear. Replace outside scrapers as neces-
sary.
25 Series Opener Side Wheels
Refer to Figure 104
1. Lift opener side wheel off ground. Move tire in and out
to check for end play. Check for roughness in bearing
by rotating wheel. If bearings are rough, inspect and
replace if necessary.
2. The side wheels are preset at the factory, however be-
cause of normal wear it may become necessary to
make adjustments so wheel remains close to the disk.
To prevent plugging loosen clamp bolt (7) and slide
arm inward to take up gap between side wheel and
disk blade. If more adjustment is needed go to step 3.
3. Remove bolt (10) and wheel (2). Remove shims (1)
from the inside of the wheel (2) and place them on the
outside of the wheel. Always place the shims removed
from the inside to the outside. When installed, the
wheel should turn freely and not hit the arm at the
curve. Do not add any more shims than necessary.
4. Disassemble side gauge wheel arm (3) from unit. Re-
move bushing (4) from sleeve (5) and check bushing
for wear. Replace bushing if necessary.
5. When reinstalling side gauge wheels, align tab on hex
adjustment (6) with notch in bushing. Replace bolt and
tighten.
6. Adjust side gauge wheels. Refer to “Adjustments,”
page 26.
