Volumetric Charts
Volumetric meter planting rate is determined by:
• crop and seed variant
• meter wheel selection, and
• meter drive configuration
The are no other adjustments.
The rates indicated in the charts are approximate val-
ues. To assure the most accurate seeding rate it is rec-
ommended that the drill be calibrated for the desired
seed at the time of planting.
Reading a Volumetric Rate Chart
Hydraulic or Ground Drive
1. Consult the chart for your crop and meter wheel.
2. Note any seed lubricant required. See “Seed Lubri-
cants” on page 2 for seed lubricant information.
3. Find the columns for your row spacing.
4. Find the desired seed rate (which is pounds per
acre for volumetric seeds).
5. Note the maximum ground speed for that rate.
6. The Range sprockets are at the top of the columns
for the row spacing.
7. The Transmission sprockets are in the table rows,
found to the left of the Seed Rate.
