Operation

General Operation Guidelines
1
Hydraulic Fan -connect the hoses in the following order:
First - connect Zero pressure Case Drain 3/8" hose (1/2" BSP Female QR) to hydraulic
reservoir *
Second -connect Motor Return 3/4" hose (3/4" BSP Female QR) to tractor high flow low
pressure return port.
Finally - connect High Pressure Motor feed 1/2" hose (1/2" BSP Male QR) to tractor remote.
Disconnect in the reverse order to prevent motor seal damage.
*The tractor hydraulic reservoir or free drain connection must have zero backpressure.
2
Use a sufficiently powerful tractor which is heavy enough to tow the drill safely.
3
Operate the drill at a speed of 6-12 km/hr (4-8 mph).
In stony and uneven ground conditions a lower speed is more appropriate
4
Check that the drill is level during calibration and while seeding.
5
Check tyre pressure before seeding.
6
Double check seed rates before seeding.
7
Raise the drill out of the ground when making any turns.
8
Raise the drill out of the ground before backing up.
9
After prolonged storage, check to see that all drive mechanisms and hydraulic equipment are functioning
correctly. Check that the seed tubes are not perished or blocked.
Sowing Speed
Typical travel speeds when sowing range from 6-12 km/hr in good conditions. In stoney and uneven
ground conditions a lower speed is recommended to minimise rapid part deterioration. Sowing too fast
can result in:
1
Poor contour following and uneven sowing depth.
2
Impact damage to:
a Ground engaging components.
b Bearings, housings & axles.
c Fasteners & structural components.
3 More extreme conditions will result in greater vibration
and uneven seed flow at low seeding rates.
