SEED HAWK ® 2015 AIRCART OPERATOR’S MANUAL 35
4.6.2 Meter Roller Selection Guide
4.7 Fans
Connect the pair of ¾” hydraulic lines (fan one has a blue band, fan two has
a red band) to supply the hydraulically driven fan motor. This tractor lever is
locked in full pressure position while seeding.
Fans are driven by hydraulic motors with speed controlled by the tractor hy-
draulic flow system. Fan speed is indicated on the monitor panel in the cab.
Set fan speed to effectively transport the seed. Higher fan speeds will increase
seed bounce, and possibly damage the seed. Higher fan speeds also require
more power input from the tractor.
Typical fan speed ranges for various product types are listed below for refer-
ence.
Product Fan Speed (rpm)
Oilseeds 2000-3000
Cereals 2500-4000
Pulse Crops 3500-4200
Fertilizer (granular) 3500-4200
NOTE: Fan Speed is depen-
dent on implement size and
tractor hydraulic output.
NOTE: If Aircart is equipped
with two fans, if one fan is
not being used, it must be ran
at low rpm due to pressur-
ization of meters.
