Half Width Clutch
Feed Flaps
Spring loaded flaps, one below each roller allows the
seeding of a wide range of seed sizes and are used to pos-
itively control the flow of small seeds to large seeds
through the feed rollers without causing bruising or crush-
ing. They also act as a safety devise for the feed rollers.
The spring loaded flap “gives” to allow a stone or other
obstructions through without damaging the rollers.
Refer to Figure 46
1. The flaps under all the rollers are adjusted by a single
lever at the right hand end of the hopper. A series of
notches in the guide bracket set the lever to the re-
quired flap opening. Position 1 is the upper setting at
which the flaps are closest to the feed roller.
Refer to Figure 47
Note: Each flap should just touch the feed roller at position
1. This is factory set, however, if adjustment is required,
tighten or slacken the lock screw below the required flap to
keep all flaps equal across the meter.
The recommended position for the Feed Flap lever setting
for different seed types is as follows:
• Position 1: Small seeds e.g. rape, when the flap is
closest to the feed roller.
• Position 2: Cereals e.g. wheat and barley.
• Position 3: Large seeds e.g. peas and beans.
Note: Refer to the seed rate charts for proper feed flap set-
ting.
Half Width Shut-Off
Refer to Figure 48
Half width shut-off provides for:
a. Seeding of a narrow width when finishing a field to
prevent double seeding.
b. To start a field in the correct sequence when tram-
lining.
To disengage, insert tool into clutch grooves and rotate
the clutch until the two drive roll pins are in line. Slide
clutch to the left until the right drive roll pin is disengaged.
Rotate clutch one quarter turn back to lock it onto the left
drive roll pin to prevent the clutch from reengaging.
Note: The left- hand side of the feed mechanism is dis-
engaged. Re-engage by rotating the clutch from it’s lock
position and allow it to slide back to the right.
NOTE: CHECK TO BE SURE THE CLUTCH HAS
FULLY RE-ENGAGED.
