c. Rotate rear roller to make sure drive system is
working properly and seed cups are free from
foreign matter.
d. Place a drop cloth under the seeder to collect all
of the seeds that are metered out.
e. Rotate rear roller the number of rotations noted in
table above. Be sure to check the three feed cups
to make sure each cup has plenty of seed coming
into it.
f. 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.
g. Next, multiply number of pounds or kilograms per
seed cup by the number of seed cups on the grass
seeds seedbox to arrive at weight “A”.
h. 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
i. If calculated grass seed rate is different than the
suggested settings in the charts, then increase or
decrease the seed cup adjustment lever.
4.
Repeat calibration procedure if the results of the
calibration vary greatly with the chart.

NOTE:
Rotate rear roller by grasping roller at the
bottom and pulling away from the seeder. Push
toward the seeder at the top of the roller.
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.
