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 Capaci-
ties” on page 144. If a suitable tractor is not avail-
able, ensure that the tongue jack is on solid ground,
and block multiple tires.
6. Lower the ladder on one side (page 42).
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 deliv-
ered 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 set-
ting 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 65, and the
Seed Rate 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 rout-
ing are optimized for specific uses. See table above.

Variable Hitch Load:
Loading materials increases the hitch load. With the imple-
ment 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
current dry ground supports the jack, sudden wet weather
could result in the jack becoming mired.
