Operation
Simplicity Australia Page 3.13 Version 1.0
Operating
pressure above 8 kpa
should be considered
excessive.
Blower speed and pressure does not control the sowing rate
but it is very important that enough air is available to move
the required amount of product from the bin to the top of the
secondary head without blocking (too little air volume) or
causing seed bounce (too much air volume)
Higher ground speeds and higher sowing rates require greater
quantities of seed and fertilizer to be moved in a given time
which requires greater air volume.
Checking Blower Speed
To check the blower speed setting, set the fan speed to
4000 rpm and remove a secondary head cap. With the
blower operating, travel forward up to normal working
speed. The material should rise 2 – 4 metres above the
secondary head. If the material rises too high or too
low adjust the blower speed accordingly.
Air Seeder Delivery Capacity
The heavy duty hydraulic motor fitted to most
Simplicity Air Seeders is rated to deliver a maximum of
one tonne per primary line depending on the bar
configuration, planting width and seed types.
Calculating Delivery Rate
The information required for calculating the delivery rate is:
 Ground speed at which the air seeder is to sow.
 Sowing rate required ie. Total kilograms per hectare
 The sowing width
The formula for calculating tonnes per hour using this
information is given below.
Speed (kph) x sowing Rate (kg/Ha) x sowing Width (m)
10000
eg. 8 x 150 x 15
= 1.8 tonnes per hour
10000
4 M 3 M 2 M 1 M
Excessive blower
speed will cause
premature hose
wear and seed
bounce while too
low a
blower speed
will cause the
material to stall in
the lines causing
blockage
