Disk Spreaders and Scrapers

Note: It is normal for the blade spreader to have some

looseness in the holder and between the blades.
Some looseness is required for proper operation.

Refer to Figure 93
1.

Remove side gauge wheels from arms to access
row-unit disks and scrapers.

With the unit raised, check blade spreader

for

wear. Replace spreader if it is

⁄

in wide or narrower.

To replace, remove disk blade

, drive out roll pins

, and install new spreader.

When reinstalling disk blades, put two shims
between bearing and shank on each blade. Tighten
bolts.

Note: You may need fewer washers on worn disks.

Check that outside disk scrapers

are formed to

disk blades to help remove any mud. Bend and twist
scrapers to fit blades as necessary. After every 200
acres of operation, check outside scrapers for proper
adjustment and wear. Replace outside scrapers as
necessary.

25 Series Row-Unit Side Wheels

Figure 94
1.

Lift opener side wheel off the 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.

The side wheels are preset at the factory. However,
because of normal wear it may become necessary to
make adjustments so the wheel remains close to the
disk. To prevent plugging, loosen clamp bolt

and

slide arm

inward to take up gap between side

wheel and disk blade. If more adjustment is needed,
go to step 3.

Remove bolt

and wheel

. Remove shims

from the inside of wheel and place them on the out-
side of wheel

. Always place removed shims from

the inside to the outside. When installed, wheel
should turn freely and not hit the arm at the curve.
Do not add any more shims than necessary.

Disassemble side gauge wheel arm

from unit.
