Meter Hand Crank
A hand crank is provided on the right 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).
The crank is stored in a ring on the frame just aft of the
right lower steps. Place it over the notched end of the
gearbox jackshaft.
Population Risk:
Rotate the hand crank only in the clockwise direction.
Operating in reverse (counter-clockwise) meters material at
incorrect rates (far too low).
The crank is used for two common tasks:
• calibration of the meter setting for planting, and
• clean-out of the meter flute chamber.
Operating the Hand Crank
Turn the hand crank 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 34, and
see “Storage” on page 37.
In general, you may operate the crank as fast as is
comfortable.
To shift gearbox and change quick-change and final drive
range gearing see “Meter Rate Adjustment” on
page 66.
Note: If gearbox clutch is disengaged, operating the hand
crank may fail to clear the meters of seed.
