Set Seed Rate Handle
There are identical seed rate handles for each half of
the drill. Generally, both need to be set identically. You
can stop seed flow to one half of the drill by setting a
handle to zero (for point-row planting, for example).
The seed rate handle controls the percent engage-
ment of the seed sprocket in each seed cup.
1. Loosen wing nut under handle.
2. Set indicator to just past value from seed rate
chart.
3. Tighten wing nut.
Position Seed Cup Doors
Refer to Figure 3, which depicts the seed cup door handle in
position
.
At each seed box seed tube, adjust the seed cup door
handle
for the seed size.
The handle has three normal operating position
detents:
(top detent) is for the smallest seeds.
Use it for wheat and similar small seeds.
(middle detent) is for larger seeds.
Use it for soybeans and similar larger seeds.
(bottom detent) is for oversize or fragile seeds. If
you experience excessive cracking with setting , use
setting .
Note: Handle position is used for cleanout, not plant-
ing. If set to this position with seed loaded, it may
be difficult to reset it to a normal operating posi-
tion.
