4.6 Metering Roller
The metering roller is provided in each compartment. The roller is divided
into replaceable sections which can be replaced if damage occurs. If there is a
damaged section the product gate above the roller can be closed to facilitate
changing without emptying the tank. The meter roller can then be removed and
repaired, quickly, without product spillage.
Some meters have two colored roller sections. The red sections have less dis-
placement 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.
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 accom-
modate 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.
