Setting Material Rates
Refer to Figure 49, which depicts a model 1625AHD
The 1625AH has three ground drive systems:
A. Seed metering, powered by a ground drive system
on each wing.
B. Fertilizer metering, powered by either a cart ground
drive (dry) or a wing ground drive (liquid, not shown).
Details for rate settings, and rate charts, are found in the
Seed Rate Manual (411-020B).
Planting (Seed) Rate
Seed rate is controlled by Range and Transmission
sprocket pairings on each wing ground drive system, and
seed meter setup at each row. The seed monitor console
reports field rates for most seed types.
1. Rate: Monitor configuration:
The seed monitor must be set up with the
• correct row count,
• correct row spacing,
• speed calibration and;
• expected population limits, in order to have accurately
rate reports and useful alarms.
See the Seed Rate Manual (411-020B) and the

IntelliAg

MVT Manual or DICKEY-john
®
PM400 Console Manual.
If you only plant with the factory configuration of the
planter, you never need to update row count and
spacing. If any rows are unused, adjust the monitor
setup.
Speed calibration must be done prior to first use, and
re-calibration is recommended periodically, particularly if
soil conditions change.
2. Rate: Disk Selection:
The Seed Rate Manual (411-020B) has a table of
recommended disks. Disks are specific to crops. Some
crops have multiple disks available, to cover both seed
varieties, and different populations within disk rpm limits.
Disks have high and low rpm limits, which also
correspond to a high and low field speed limits. The
charts account for these limits.
See “Air-Pro
®
Meter Disk Installation” on page 81.
If any rows are unused, install special blank disks. See
“Row Unit Shut-Off” on page 83.
