18. Slowly turn on flow of grain and fill bin. Slow down and
then stop flow of grain as level nears the top of the bin
to avoid overflow.
19. Turn off the auger and return to storage position. Re-
place the storage lock pin and clip. Be sure that the
handle latch is secure.
20. Turn off the tractor hydraulics and then return the flow
diverter valve handle to innermost (fold) position.
!
CAUTION!
Do not turn the diverter handle until the hydraulics have been
shut off. If it is moved with hydraulics still on, the implement
wings will suddenly begin folding.
21. Remove any foreign matter from strainer basket.
22. Wipe any grain or foreign matter from lid seal flange
area on top of bin. Close lid and securely latch.
23. Before moving the drill check that the bin lid is latched,
the auger control is off, the flow diverter handle is in-
ward, and the auger is securely latched in transport
storage position.
Field Operations
1. Be sure that the cart tires are properly inflated as indi-
cated in the Tire Inflation Chart in the “Appendix”
section on page 86.
2. Be sure that all hoses are connected and clear of for-
eign material. Make sure openers are not plugged.
3. Never back up with the openers in the ground. Do not
turn sharply with openers in the ground, doing so will
cause openers to plug.
4. Set the seed rate as described in the Setting the Drill
Seeding Rate portion of the “Adjustments” section
on page 46.
5. Turn on the fan hydraulic motor. Be sure the fan ro-
tates correctly.
6. Check all bin seals to make sure no air is leaking. Ad-
just the latch or replace the seals to prevent leakage.
7. Make sure that nobody is in the way of the drill before
moving. Do not allow anybody to ride on the drill.
8. Set the tractor engine idle to an approximate field
speed. Adjust the tractor flow control valve until the fan
pressure gauge reaches approximately 21” of water
(12 ounces per square inch).
Heavy seeding rates may require a higher setting.
Light rates or very fragile seeds may require a lower
setting for best distribution or if excessive crackage is
evident.
9. Turn on the electric clutch switch in the cab. With the
fan running drive forward and lower the implement to
begin seeding.
10. Do not shut off the fan motor while seed is being me-
tered. Doing so will cause the distribution hose to
plug. Do not rely on the tractor detent to hold the lever
on. Use a rapidly removable strap or hook to hold the
lever in place.
11. With a properly adjusted implement height switch it is
not necessary to turn the electric clutch switch on and
off manually while turning. The clutch switch should
be turned off while transporting.
12. Be aware of a slight 5‘-10’ delay needed for the seed
to reach the openers when starting. If you stop in the
middle of the field lift the drill and back up 10‘ then
start from there.
13. Always operate farm machinery with safety in mind.
Implement Lifting System
The implement lifting system is equipped with rephasing
type hydraulic cylinders in a master-slave configuration.
They must be bled free of air using the procedures listed in
Bleeding the Hydraulic Lifting System in the “Implement
Assembly and Setup” section on page 24 for proper op-
eration. The cylinders may, after a period of time, get out of
phase. This will cause one section of the implement to run
higher or lower than other sections because the cylinders
lifting it are extended more or less than the others. To
NOTE: When leveled off, the top cone of the bin holds
approximately 50 bushels; the center area 50 bush-
els; and the lower cone 50 bushels.
NOTE: Fan motor circuit is equipped with a check
valve to allow the fan to wind down freely when shut
off. The bottom of the fan rotor should rotate towards
rear of the cart.
NOTE: It only takes a very small air leak to cause a
large variation in the seeding rate.
NOTE: Always engage the fan motor with the tractor
at a low idle speed. Do not reverse hydraulic flow with
the fan running.
NOTE: The electric clutch circuit contains 2 switches
besides the in-cab control. One switch requires that
the fan be running at a suitable speed before seed is
metered to prevent the hose from plugging. The other
switch is on the implement and only turns on the
clutch when the implement is lowered below the ad-
justed height. See Electric Clutch Height Switch in
the “Adjustments” section, on page 63, for more in-
formation. If you wish to run seed through the system
while the drill is stationary you must use the hand
crank as described in Setting Seeding Depth and
Leveling Front-to-Rear in the “Adjustments” section
on page 60.
