Small Seeds Seed Rate Adjustments
Refer to Figure 5-1:
1. Use English charts on page 47 and Metric charts on
page 50 to help determine seeding rate.
2. Move small seeds seed rate adjustment lever to cup
setting number obtained in the seed rate charts. For
best results, first move adjustment lever all the way to
the left and then to the desired setting. Increase
setting if seed is lighter than average. Decrease
setting if seed is heavier than average.
3.
Refer to Figure 2-13 on page 33:
Engage small
seeds with lock in/out pin (#3). Disengage native
seeds lock in/out pin (#2) and set grass seeds
transmission in neutral. Refer to
“Calibrate Small Seeds Dispersal”

1. Attach seed rate crank to the all seeds drive sprocket.

Small Seeds Seed Rate
Adjustment Lever (Cup Setting)
DO NOT operate seeder with
adjustment lever set on 0.
IMPORTANT:
Never operate small seeds seedbox
with seed rate adjustment lever set at 0.
Always
disengage lock in/out pin (#3) shown in Figure 2-13
on page 33 to stop seed cups from turning. Allowing
any of the seed cups to turn with the adjustment
lever set at 0 will damage the cups.
NOTE:
Before filling the small seeds seedbox,
make sure all seed cups will fully close when moving
seed rate adjustment lever to 0. Any seed cup that
will not fully close will discharge seeds at a higher
rate. See
“Small Seeds Zero Adjustment Set-up”
on page 15 for detailed instructions.
NOTE:
Seeding rates will vary greatly with variations
in seed size, seed treatment, weight of seed, soil
surface condition, and rear roller slippage. We
recommend that you test and adjust your seeder
using the calibration procedures listed below to help
ensure an accurate seeding rate.

2. Partition off three of the seed discharge openings
located inside the small seeds seedbox.
3. Pour seed over the three discharge openings.
Do not
allow any seed to reach any of the other openings.
4. Pull seed tubes out of the three seed cup drops.
5. Crank rear roller to make sure drive system is
working properly and that the feed cups are free from
foreign matter.
6. Place a container under the three seed tubes to
gather seed as it is metered.
7.
Crank rear roller the number of rotations noted in the
table above. Check the three cups to make sure each
cup has plenty of seed coming into it.
8. Weigh the seed which has been metered out and
divide that weight by three to get the number of
pounds or kilograms per seed cup.
9. Next, multiply number of pounds or kilograms per
seed cup by the number of seed cups on the small
seeds seedbox to arrive at weight “A”.
10. If weight “A” is calculated based on:
1/10 acre, then “A” x 10 = lbs/acre
1000 sq ft, then “A” x 43.56 = lbs/acre
1000 sq ft, then “A” x 1 = lbs/1000 sq ft
1/20 hectare, then “A” x 20 = kgs/hectare
100 sq meters, then “A” x 100 = kgs/hectare
100 sq meters, then “A” x 10 = kgs/1000 sq m
11. If calculated grass seed rate is different than the
suggested settings in the charts, then increase or
decrease the seed cup adjustment lever.
12. If calculated seed rate varies greatly with suggested
settings in the charts, then increase or decrease the
seed cup adjustment lever shown in Figure 5-1.
13. Repeat calibration procedure if seed cup adjustment
lever was moved in step 12 above.
14. Remove and store seed rate crank. Refer to

NOTE:
If total weight for 3 seed cups is in
ounces, divide that weight by 48 instead of 3.
NOTE:
Field conditions will affect seeding rates.
Check amount of seed being used by noting size of
area being seeded, amount of seed added to the
seeder, and level of seed in the seedbox.
Minor adjustments to the seed rate adjustment lever
may be necessary if seeder is seeding more or less
seed than desired.
