4.4 METERING ROLLER
The metering roller provided in each compartment is designed to
accommodate every / all product for seeding small oil seeds to large pulses
as well as granular fertilizer.
There are sections that make up the roller which can be replaced if damage
occurs. If there is a damaged section the product gate above the roller can be
closed if there is still product in the tank.
NOTE: Ensure roller is gate is reopened to commence seeding.
There are two colored roller sections on some meters. The red sections have
an 11% less displacement that the black sections. When a machine’s air
distribution system has tower heads with different outlets your seeding rate
can be up to 11% out.
EX:
64’ with 12” spacing tool bar has 64 runs.
Having 8 outlet meter feeding 64 runs; every tower would have 8 runs
per tower. The roller sections are all black for this example.
EX:
65’ with 10” spacing tool bar has 78 runs.
Having an 8 outlet meter feeding 78 runs; the furthest towers will have
to be 9 run heads and the other 6 towers would need 10 run heads. A 9
run head has an 11% higher seeding rate than a 10 run head. The red
sections are then used to decrease the seeding rate for the 9 run
heads by 11%. Having done this, the seeding rate across the tool bar
will be even.
