Setting Sensor Depth
Refer to Figure 30
The “T” handle (1) sets sensing depth by limiting the how
high the side depth gauge wheels ride relative to the
opener disks. To adjust sensing
depth, pull the “T” handle
(1) up and back,move it forward or aft, and set it back in a
different pair of holes in the scale.
• For shallower sensing, move the “T” handle (1) forward.
• For deeper sensing, move the “T” handle (1) back.
Opener Disc Contact Region
Refer to Figure 31
Opener disc angle and stagger is not adjustable, but
disc-to-disc spacing is, and may need attention as discs
experience normal wear. Spacers will need to be reset
when blades are replaced.
The ideal spacing causes the blades to be in contact for
about one inch (4) . If you insert two pieces of paper
between the blades, they should slide to within zero
(touching) to 1.5in (3.8cm) of each other. If zero, the gap
between the blades should not be significantly greater
than the thickness of two sheets of paper.
If the contact region is significantly larger or there is a
large gap, it needs to be adjusted by moving one or more
spacer washers.
Adjusting Disc Contact
Refer to Figure 32
1. Raise the Implement.
2. Remove the side gauge wheels (5) on the row unit in
need of adjustment.
3. Remove the bolt (6) retaining the opener disc (7) on
one side. Carefully remove the disc. Do not lose the
hub components and spacer washers (8)(9).
4. To reduce the spacing between the discs (the normal
case), move one spacer washer from the inside (8) to
the outside (9) of the disc.
5. Re-assemble and check disk contact
.
