Application Rate Risk:
Make field checks to assure you are applying fertilizer at the
desired rate. Fertilizer application rates can vary from the
weights in the charts.
Use the following instructions to check the exact number
of kilograms your fertilizer attachment delivers on a 70cm
row spacing.
1. Adjust for your fertilizer density (page 38).
2. Consult the Fertilizer Rate charts (page 38).
3. Install the Driving and Driven sprockets called
out in the chart.
4. Remove a hose from one of the fertilizer hoppers
and attach a container under the opening.
5. Engage the fertilizer attachment and drive forward
for 142.9 m (469 feet).
6. Weigh the amount of fertilizer caught in the container
and multiply that amount by 100. The result will be
the kilograms of fertilizer delivered per hectare when
planting in 70 cm rows.
To assure proper application check the gauge tires and
contact drive tire for proper inflation, see “Tire Inflation
Chart” on page 97.
