DIFFICULT SEEDS TO SOW
There are a number of seeds that are difficult to sow due to their physical shape and
weight.
These include:
Prairie Grass
Buffel Grass
Callida Rhodes Grass
Unclipped oats
If seeds adhere to the sponge pad, fit the oat wiper (Part # A2366). If there are
problems with large seeds failing to pick up with the sponge it will be necessary to fit
the bean spacers (Part # A2365-01) which space out the pads leaving a greater surface
to pick up seed.
OAT WIPER AND BEAN SPACER
Bean Spacer (Optional)
When sowing large smooth seeds such as beans markedly improved seeding
performance is achieved by fitting spacers between the sponge and the seeder casting.
This in effect moves the sponge away from the seeder casting and allows for better
entry of the seeds into the sponge. A better ‘pick up’ is attained and seeding
consistency is improved.
Also to decrease the advent of intermittency and improve seed spacing it is advisable
to use the seeder agitator set on maximum spring pressure.
To fit the spacers follow these instructions:
1. Pull the sponge away from the seeder casting.
2. Fit the Bean Spacer between the sponge pad and the seeder unit.
3. Allow the sponge pad to return to the seeding position with approx 3mm
(1/32”) between the sponge pad and seeder unit.
WARNING:
When the bean spacers are fitted always go back and recalibrate
the drill.
If small seeds need to be sown (i.e. grass seed,
brassicas) or small grains (i.e. wheat) always
remove the spacers and store in a safe place.
