Seed Cleanout
Refer to Figure 140, which depicts the seed cup door handle
in a normal operating position .
1. For large quantities of remaining seed, use a bucket
to scoop out from above, as this may be easier than
collecting under row units.
2. Set all Seed Rate Handles to zero (0). This moves
the seed cup sprockets out of the seed path.
3. Position a tarp or bucket under each row or set of
rows to be cleaned out.
4. At the seed cup for each row, pull the door handle
out of the operating detent range, and swing it down
to position
.
5. Open the main seed box and use a small brush to
sweep seed toward seed cups set to clean-out. If
seed does not flow freely, inspect seed cup, hose
and seed tubes for obstructions.
6. Wash out the seed box with high pressure water.
It is not necessary to operate the seed meter drive shaft
for clean-out. With the Seed Rate set to zero, nothing
moves inside the seed cups; however, an inspection of
the flutes for excess wear and damage does require
shaft rotation.
Set the Seed Rate Handle to 100. Use an open-end
wrench to turn the seed meter jackshaft, while another
person inspects the flutes from the open seed boxes.
Frame Alignment and Level
Adjusting Fold Cylinders
If the drill does not fold or unfold fully it may be neces-
sary to add or remove shims from the base of the wing
fold cylinder.
Refer to Figure 141
1. With the drill in the folded or unfolded position make
sure drill is on level ground and all safety locks are in
place.
2. Place tractor in park, turn off ignition and remove
ignition key.
3. Remove bolts from cylinder base plate and add
or remove shims as necessary.
4. Tighten fold cylinder base bolts and activate fold cyl-
inders to make sure wings travel to full open and full
closed position. If not repeat above steps until full
open and full closed are achieved.
