Cleaning Chemical Hoppers
!
DANGER!
Agricultural chemicals can be dangerous. Follow the instruc-
tions of the chemical manufacturer when cleaning hoppers and
handling insecticides or herbicides.
NOTE: Under certain humidity or moisture conditions, ma-
terial may tend to cake. When this happens, thoroughly
clean hoppers at the end of each day’s use.
To remove hoppers, proceed as follows:
1. Disengage drive clutch.
2. Unlatch.
3. Lift off.
4. Clean thoroughly.
Cleaning Liquid Fertilizer Tanks
!
DANGER!
Agricultural chemicals can be dangerous. Follow the instruc-
tions of the chemical manufacturer when cleaning hoppers and
handling insecticides or herbicides.
Although the tanks are made of a highly durable and cor-
rosion resistant plastic, proper maintenance is required.
Rinse the tank with water when changing from one solu-
tion to another.
Rinse tank thoroughly with water after each season or be-
fore any shutdown lasting over one week.
Do not allow sludge to accumulate in the bottom of the
tank.
Do not leave fertilizer in the tanks if the temperature is ex-
pected to drop below 40 degrees as some types of liquid
fertilizers will begin to crystallize at this temperature.
To clean tanks, proceed as follows:
5. Remove lids from tanks.
6. Turn valve to elbow.
7. After cleaning tanks, close shutoff valve, replace cap
on metering pump and replace lids on tanks.
Squeeze Pumps
Refer to Figure 7-14:
During periods when the pump is not being used, these
important steps are recommended to prevent hose defor-
mation and prolong hose life.
1. Unscrew (about 1/2 inch) the wing nuts holding the
spring anchor bar to the pump frame. This releases
pressure against the hoses.
2. Loosen the wing nuts on the discharge manifold and
shift the manifold rearward.
3. Store out of sunlight.

Marker Breakaway Protection
The marker arm is attached to the marker body with a
5/16" breakaway bolt. If excessive force is put on the mark-
er during operation, the bolt will break, allowing the marker
arm to swing away rather than cause damage to
the marker.
IMPORTANT: The breakaway bolt is a 5/16"-18 x 1 1/
2" long grade 2 on planter only (GP #802-295C). If it
breaks, it must be replaced by an equivalent grade 2
bolt to prevent marker damage.
Storage
To extend the life of your planter follow the recommenda-
tions for removing the planter from storage and storing the
planter during the off season.
Beginning of the Season Service
Before using the planter after it has been stored, inspect
the seed hoppers for cleanliness to be certain the seed will
flow from hoppers freely.
Thoroughly inspect the planter unit for loose parts and ad-
just as necessary. Check all bolts and replace worn parts
to prevent failure in the field.
Clean any dirt or grease that may have accumulated on
moving parts, and chains before operating the planter.
This will prevent abrasive action that could cause exces-
sive wear.
