6.3 HYDRAULIC SYSTEM
The Air Cart is equipped with a hydraulic system to:
1. Drive the fan motors
2. Drive the motors on the seed and fertilizer metering units
3. Lift and lower the hydraulic parking jack
4. Feed the remote points (only applicable to tow-between models)
5. Position the auger and drive the auger motor.
A detailed schematic depicting the complete hydraulic circuit is provided at the end of this
manual.
OIL FLOW REQUIREMENTS FOR EACH FUNCTION
1. Fan motor = 50 L/min per fan
2. Seed meters = 50 L/min
3.
Remote points = dependent on hitched implement’s requirements.
NOTE: The hydraulic parking jack and auger is only used during hitching and during refilling
respectively and therefore do not require continuous hydraulic flow.
AUGER/HYDRAULIC DRIVE SELECTION
The auger and hydraulic drive (metering units motors) runs on a single pressure line from the
tractor (marked as hydraulic drive) due to the fact that only one of these two functions are in
use at any given moment. A three-way valve, located in the front left section of the Air Cart,
allows for selection between these two functions. A high-pressure filter mounted upstream of
the valve provides filtration.
