Small Seeds Box
The Small Seeds Box is an optional extra designed to fit most
Simplicity Australia Air Seeders and is supplied factory fit when the
seeder is manufactured or can be retro fit at a later time.
The small seeds box is available in five different litre capacities
dependent on the Air Seeder to which it is to be fitted.
3000 litre air seeders can be optioned with a 200 litre small seeds box.
4500 225 litre
6000 300 litre
9000 450 litre
12000 600 litre
15000 600 litre
The small seeds box is used for sowing small seeds at low rates.
Small Seeds Box Calibration
To achieve accurate sowing rates it is important to have available:
 An accurate set of scales.
 A bag of seed that is to be sown.
 A method of catching the metered material for weighing.
 The number of calibration handle turns per hectare
established during the Air Seeder calibration.
Step 1: Remove the bottom calibration door of the metering unit to
enable small seed to be metered, collected and weighed for checking
and setting the desired sowing rate.
Note: The small seeds box metering unit does not have a swing away
door similar to other bins on the Airseeder. To remove the door the
two retaining wing nuts must be loosened and the door removed.
Step 2: Remove all other bin metering unit shafts. This will enable the
small seeds box to be calibrated without turning and overloading any
other metering unit.
Step 3: Place a tray under the small seeds box metering unit to catch
the metered material for weighing.
Step 4: Make sure the clean out door is closed and locked. Place a
small amount of seed into the small seeds box. Do not completely
fill the small seeds box until calibration is complete.
Step 5: Adjust the calibration dial on the Zeromax box to 50% for the
initial calibration.
Step 6: Using the large metering shaft calibration handle, turn the
calibration shaft in a clockwise direction for the set number of turns
previously established during Airseeder calibration. It will be necessary
to turn the calibration handle the number of turns required for ¼
hectare. Increasing the number of crank rotations during the final
testing will ensure greater accuracy.
Do not loosen or
move the lock
nuts on the
pointer assembly.
These lock nuts
are factory set
and altering the
position will
serve no purpose
