Loading Dry Fertilizer (Twin Row)
Loading liquid fertilizer is found on page 29.
If fertilizer will not be applied, uncouple the fertilizer
meter shaft at the left end of the left hopper. Pin the
coupler clear of the shaft joint.
Loading fertilizer prior to transport is not recommended.
Although the meters are not turning during transport, it is
possible for some material to spill through the meters,
particularly on rough roads.
Suitable Materials
Use only dry granular fertilizer. Granules must flow freely,
and must have a maximum diameter smaller than 7 mm
(to avoid bridging clogs in the applicator tube outlets).
Agricultural Chemical Hazard:
Wear protective equipment suitable for the material to be used,
and the material previously dispensed from the hoppers. Avoid
contact with skin or eyes. Avoid breathing dust.
System Inspection
Verify that both rear cradle pins are installed on all
hoppers. See Figure 111 on page 100.
Refer to Figure 29
Remove the lid on each hopper and inspect for:
• residual fertilizer incompatible with next use
• contaminants
• debris that might clog the meter inlets
• trapped animals lost tools, etc.
If it is necessary to clean a hopper, see “Dry Fertilizer
Clean-Out” on page 100.
Hopper Lid Operation
Refer to Figure 30 and Figure 32
To unlock the hopper lid, lift the rubber latches
out of
the metal keepers
.
Note: The keeper hardware
tends to snag under the
hopper lip. Pull the lid edge forward and lift.
Refer to Figure 31
To open the lid, lift the front edge up and slide the lid
back into a vertical position behind the hopper. The lid is
held by retaining straps
.
Refer to Figure 30, 31 and 32
When closing the lid make sure that:
• the rear catch plates
are under the hopper rear lip,
• the keeper hardware
is under the front lip, and
• the ball of each rubber latch
is seated in the keeper.
(If only the handle “T” is seated, the lid is not secure.)
