6.5.4 - Rotors
As part of the metering assembly above the rotor chamber there is a stainless steel guillotine door.
All meters are supplied with 6 x 75cc and 6 x 150cc metering wheels and 6 x spacer wheels as
standard. This combination will allow for common seed rates and speed options.
The 75cc meter wheels are used for small grains (Wheat, barley, Oats etc). The 150 cc are used for
large grains (peas, beans etc). The metering roller variants can be found in the appendix on pg 71.
