Fertilizer Box Clean-Out
After applying fertilizer, clean the box as soon as
possible. Fertilizers often contain corrosive chemicals.
Refer to Figure 65
With a small scoop or can, remove as much fertilizer as
possible from drill boxes.
Clean-out releases material across the entire length of a
box. Have collection equipment prepared.
Release all clean-out latches on the drill, and open
clean-out door. Leave door open until after washout.
Wash inside of fertilizer box with high pressure water.
Let drill boxes dry before closing clean-out doors.
Small Seeds Box Clean-Out
1.
Open box lid and scoop out as much seed as
possible.
2.
To recover remaining seed, place a collection tarp
under the small seeds tubes at the openers.
3.
Raise drill.
4.
Set seed rate handle to 100.
5.
Rotate calibration crank or end wheel until no seed
flows.
6.
If a vacuum cleaner is available, remove any residual
seed from top of meters.
Chain Maintenance
Inspect and lubricate chains regularly. The slack of new
chains tends to increase during the first few hours of
operation due to seating.
Chain Slack
Check slack within the first 8 hours of operation and
tighten idlers as necessary.
Refer to Figure 66, which, for clarity, greatly exaggerates
slack, and omits the idlers.
1.
Measure the span
for allowable slack:
Locate the longest span of each chain (usually the
span which does not run through the idlers).
2.
Measure the current slack:
Acting at a right angle to the chain span at the center
of the span, deflect the chain in both directions with a
force of about 9 lbs (4 kg). The slack is the distance
of the movement.
3.
Adjust the idlers for ideal slack
.
Whenever mounting a chain, make sure the clip at the
removable link is oriented to minimize snags.
Refer to Figure 67
Install clip with open end facing away from direction of
chain travel (shown by gray arrows in chain routing
diagrams).
