SEEDHAWK

PRESSURIZED

METERING SYSTEM

FAN(S)

Some models are configured

with a single fan while others

may be configured with dual

fans. Fans are driven by

hydraulic motors with speed

controlled by the tractor

hydraulic flow control system.

Fan speed is indicated on the

monitor panel in the cab.

Set fan speed to effectively

transport the seed. A reminder

that 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 reference:

PRODUCT FAN SPEED

(rev/min)

Oilseeds 2000 - 3000

Cereals 2500 - 4000

Pulse crops 3500 - 4200

Fertilizer (granular) 3500 - 4200

NOTE: Fan speed is dependent on implement size and tractor

hydraulic output.
