Meter Installation
Note: Applies only to 10HD and 25 Series openers.
Installation is the reverse of the removal process, with
two steps omitted.
Refer to Figure 106
1.
Insert the meter.
Insert the top meter tab (with the hook).
Align the meter base with the latch plate ears.
Insert the bottom meter tab.
Mind the lower latch, as it tends to swing under the
meter base and block mating with the latch plate.
Refer to Figure 99 on page 79
2.
Engage the upper latch, and swing the mounting
plate into engagement with the meter.
Note: Always engage upper latch first.
Refer to Figure 100 on page 80
3.
Engage the lower latch.
Refer to Figure 99 on page 79
4.
Slide the seed hose over the meter inlet tube, and
then slide the retaining ring down the seed hose.
10HD, 25 Series Finger Meter Adjustments
Note: Applies only to 10HD and 25 Series openers.
The finger pick-up meter has an adjustable brush, and
alternate inserts are available for the backing plate. The
brush has been pre-set to the optimum setting for most
seed sizes. The factory-installed insert is the “A” insert.
Optimum planting speed is 4
1 ⁄
2
to 5 miles per hour
(7.2 to 8 kph). Excess speed causes poor spacing
performance due to seed tube bounce, and may also
cause improper depth control due to row unit bounce.
Always pay attention to your drill monitor. Compare
actual seed usage to your estimates.
Fine-tune your drill by thoroughly checking all key
components including: seed tubes, chains, sprockets,
tire pressure, seed monitor, double disk openers, gauge
wheels, seed firmer, closing wheels, parallel arms, and
the row unit itself.
