Meter Hand Crank
A hand crank is provided on the left side of the cart for
manual operation of the meters (the meters otherwise
turn only when the cart is in motion with the clutch
engaged).
Equipment Damage Risk:
Rotate the hand crank only in the counter-clockwise direction,
as shown in Figure 32. Operating in reverse (clockwise) can
cause meter gear box damage.
The crank is used for two common tasks:
• calibration of the meter setting for planting, and
• clean-out of the meter flute chamber.
Installing Crank
Refer to Figure 31 and Figure 32
6. Remove the pin from the crank shaft behind the
outer crank bracket.
7. Pull the crank out of the inside bracket (only)
and slide the end of the crank shaft onto the outside
end of the meter jackshaft
. Re-insert the pin in the
crank shaft so it doesn’t get lost.
Operating the Hand Crank
Refer to Figure 32
Turn the hand crank counter-clockwise to simulate meter
operation during planting.
Specific recommendations may be made in applicable
manual sections. See:
see “Meter Calibration” in the Seed Rate manual,
see “Unloading the Cart” on page 47, and
see “Storage” on page 55.
In general, you may operate the crank as fast as is
comfortable. For reference, at a field speed of 6 mph, the
jackshaft rotates at 150 rpm (2.5 turns per second).
For clean-out, make sure the variable rate gearboxes
are set:
• above “10” if the final drive range gears are in
High Range mode, or
• above “80” if the final drive range gears are in
Low Range mode.
To change variable rate gearbox and final drive range
gearing see “Setting Material Rates” on page 56.
Note: If variable rate gearbox is set to “0”, operating the
hand crank may fail to clear the meters of seed.
