Loading Seed or Dry Fertilizer
Loading: Use a Tractor
5.
Securely hitch drill to a tractor with adequate weight
and power. Park drill on solid, level ground. See
Tractor Requirements, “Specifications and
Capacities” on page 149. If a suitable tractor is not
available, ensure that the tongue jack is on solid
ground, and block multiple tires.
6. Lower the ladder on one side (page 46).
Loading: Select Hoppers to Use
Refer to Figure 41
Single-Hopper Configuration
For single-hopper drills, all materials are delivered to the
row unit seed tubes, and are placed in furrow.
Dual-Hopper Single-Shoot Configuration
On a dual-hopper “single-shoot” drill, either hopper may
be used for seed and/or fertilizer. All materials are
delivered to the row unit seed tubes, and are placed in
furrow.
If applying the same material from both hoppers, you can
meter from both simultaneously, or from one at a time,
sequentially. For sequential metering, the unused hopper
is disabled by removing a final Range gear.
Simultaneous metering avoids weight imbalance and
eliminates stopping before the halfway point for meter
change-over. However, avoid simultaneous metering if it
would result in a Low Range variable rate gearbox
setting below a scale value of 20.
If metering simultaneously, set each meter for one half
the chart (or calibrated) rate. Do not merely use half the
single-meter scale setting, as this is usually not half the
rate. See “Setting Material Rates” on page 69, and the
Seed Rate Chart Manual for more details.
Dual-Hopper Double-Shoot Configuration
On a dual-hopper “double-shoot” drill, the factory default
configuration is that the hoppers and delivery hose
routing are optimised for specific uses. See table above.
Auger Discharge Heights
Hopper Intended Hopper Use
I (Left) Seed or In-Furrow Dry Fertilizer
II (Right) Dry Fertilizer or Broadcast Seed
Hopper Elevation to Flange
2890 litre (82 bu) 2.83m (9 ft. 0 in.)
5290 litre (150 bu) 2.97m (9 ft. 1 in.)
Variable Hitch Load:
Loading materials increases the hitch load. With the
implement lowered, and its circuits in Float, a full material
load results in a hitch load of nearly 1900 kg (4200 pounds).
This results in a jack load of up to 25 kg/cm
2
(350 psi). Even if
the currently dry ground supports the jack, sudden wet
weather could result in the jack becoming mired.
