Operating Instructions
12. With lid tilted forward at a slight angle, hook the two
front hinge lugs under the hopper lip. Swing down,
keeping fingers clear of lug, and latch the single rear
lid lug on rear hopper lip. Check that all 3 lid lugs are
completely under the hopper lip, or the lid may come
off in transport.
Seed Drive Clutch
Meter Clutch Disengagement
The seed meter may be disengaged from the drive
system, as required in several situations, for example:
•
hopper removal for clean-out, meter exchange or
maintenance
•
treatment meter calibration
•
application without seeding
To disengage a meter, pull the knob
away (left) of the
row unit. Rotate the knob until the inner cross-pin
is
seated in the shallow detents
of the hub.
Meter Shaft Alignment
The meter clutch and meter-input shaft must be aligned.
Misalignment causes meter malfunction and excessive
meter-housing and clutch wear. Periodically check
vertical and horizontal alignment of meter clutch and
meter-input shafts.
1.
Latch hopper onto hopper support cross-tube.
2.
Check that the roll pin
in the end of the meter input
shaft is centered. When centered, equal amounts of
the roll pin protrude from both sides of the shaft.
3.
Rotate the meter input shaft so that the roll pin is
vertical.
4.
Rotate the drive coupler
on meter clutch so that
the slots are vertical.
5.
Release the meter clutch to engage the meter input
shaft.
6.
If shafts are aligned vertically, the drive coupler
engages with the meter input shaft freely and the roll
pin extends equally on each side of the drive coupler.
Disengage the clutch and repeat steps, checking for
horizontal alignment.
7.
If the drive coupler does not freely engage the meter
input shaft vertically and horizontally, loosen the
5
16
inch nuts
on the flangette. Engage the meter
clutch. Align the meter clutch with the meter input
shaft. Tighten the nuts
5
16
inch nuts to Grade 5
torque specification.
