37 Maintenance and Lubrication
Don’t ignore your planter monitor. Check
seed use. Investigate discrepancies that
could indicate problems with your row unit
or meter.
Precision™ Meter
Precision™ Meters have been tested to ensure
that they pass quality standards. These tests
are conducted using medium flat seed and the
“A” insert. Seed size and shape will vary and
can change meter performance. For optimum
performance, have your meters calibrated with
seed by a MeterMax® technician.
Precision™ Meter General Planting Tips.
Optimum planting speed is 4 1/2 to 5 miles per
hour. Excess speed results in poor spacing per-
formance and improper depth control. Fine-
tune your planter by checking all key compo-
nents including: Keeton™ Seed Firmers, seed
tubes, chains, sprockets, tire pressure, seed
monitor, double disk openers, gauge wheels,
closing wheels, parallel arms, and the row unit
itself.
Precision™ Meter Annual Maintenance.
Check your Precision Meter annually. Inspect
Population Max, Skip Stop, and the SureFire
seed belt. Replace the brush every year. Only
use a Precision Planting Adjustable Brush or
maroon colored brush in Precision Meters; oth-
er brushes are too stiff and will increase skips.
The insert will eventually show some wear and
can easily be replaced. The perimeter wearstrip
is also replaceable. Please consult with a
MeterMax representative regarding
replacement.
Precision™ Meter Warnings.
1. The use of seedbox treatments will affect
meter performance and wear of meter com-
ponents. Precision Planting will not be re-
sponsible for performance and rapid wear
when seedbox treatments are used.
2. Generally, meter performance is enhanced
with graphite if using Captan, Cruiser, Pon-
cho, or other seed treatments. If graphite is
needed, use Precision Planting Graphite or
EZ-Slide which is less abrasive then the
planter manufacturer’s powder graphite.
3. Always store meters in a dry, secure place
to avoid moisture, temperature extremes,
and mice. Also, be sure to store meters with
brush between two fingers, so fingers are
not pressing on brush.
