OPERATION AND MAINTENANCE
Loup II Drill Monitor Operation
1. The 5531 Grain Drill is equipped with a Loup II drill
monitor. The drill monitor will monitor population from
two sensors on each box, seed box levels on the
center and outer two seed boxes, as well as acres
planted.
2. Population readings are 95% accurate for soybeans.
When planting smaller seeds the population
accuracy will be reduced. This does however give
you a reliable indication that all sections are planting.
The monitor may be adjusted to set high/low
population alarms. Do not use the monitor to
calibrate the seeding population. To calibrate the drill
either by weight or seed count, see “Seed Rate
Calibration” on page 4-19.
3. Bin level sensors are installed in the center seed box,
and the outer end of the outer most wing seed box.
When the sensor is submerged in seed, no alarm will
sound. As the seed level falls below the sensor eye,
an alarm will be indicated on the drill monitor. The bin
level sensor is mounted to an adjustable bracket.
The bracket may be raised or lowered to the desired
level in the seed box.
4. The drill monitor will also monitor field and total
acres.
5. Pulses are preset for the drill monitor. Initially the
pulses are set at 68. The pulse setting may vary
depending on the conditions the drill is planting in.
Worked or loose sandy soils will have a different
setting than firm no till conditions. For greater
accuracy on the pulse setting, calibrate the drill
monitor in the desired working conditions. This is
done by driving a known distance (400 ft) and
recording the number of pulses in that distance.
Refer to the Loup manual for instructions.
6. The drill monitor is operated on a 12-volt dc negative
ground system. The monitor may be connected using
the existing connection, or may be hard-wired to the
appropriate connections. Connect the red wire to a
positive terminal that is on when the tractor switch is
on. Connect the black wire to a chassis ground on
the tractor maintaining good metal-to-metal contact.
7. The signal cable attaches to the monitor and
connects to the drill. The cable may be
plugged/unplugged at the front of the drill hitch when
hooking/unhooking the drill. This allows the monitor
to stay in the tractor is so desired.
