4.7 METERING ROLLER
The metering roller, Figure 25, is provided in each compartment. There are four
different roller section types: canola, helical, straight fluted (bean) and chick
pea. However, the canola roller is only available on hydraulic drive equipped
aircart models. The helical roller section is designed to accommodate the
majority of seeding products including small oil seeds, cereals, and granular
fertilizer. The straight fluted (bean) roller is used for small pulses and granular
fertilizer. The chick pea roller should only be used for very large pulses such as
garbanzo beans.

These 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. The meter roller can then be removed
and repaired without product spillage or the need to unload the tank.
NOTE: Ensure roller gate is reopened to commence seeding.
There are two colored roller sections on some meters, as seen in Figure 25.
The red sections have less displacement than the black sections. When a
machine’s air distribution system has tower heads with different outlets the
heads with the lower number of outlets are fed by red roller sections to ensure
even distribution.
