1. Raise seedbox lid (J) for hardware installation.
2. Position new upper drive sub-assembly at location

where pre-existing upper drive sub-assembly (D)

was removed from.
a. Secure upper drive sub-assembly to the

machine with two 5/16-18x1 GR5 bolts (#28),

flat washers (#42), lock washers (#40), and hex

nuts (#34).

Installing New Chain Guard Mounts

WARNING

To avoid serious injury or death:
Wear the appropriate personal protective equipment and

clothing when performing tasks such as using a cutting torch,

grinding, and/or welding.

Refer to Figure 1-4 & Figure 1-5 on page 4:

1. Ensure area where new chain guard mounts are to

be welded are void of gouges, and/or excess material

that still needs to be removed.

2. Measure out and mark locations on seeder frame for

placement of new chain guard mounts (#11 & #12).

Refer to Figure 1-4 below for the needed dimensions.

Figure 1-4

3. Secure both chain guard mounts (#11 & #12) to new

chain guard (#10) with two hand knobs (B). This will

set the angle needed for each chain guard mount.

Refer to Figure 1-5 on page 4.

4. Mount and secure chain guard (#10) to the top of

upper drive sub-assembly mount (#4) with the last

hand knob (B).

5. Verify that each chain guard mount is lined up to the

measured out markings made in step 2.

NOTE:

To achieve a good arc for welding, proper

penetration, and contaminant free welds, ensure

paint has been removed from the seeder’s steel

frame where the new chain guard mounts

(#11 & #12) will be welded to.
