Small Seeds Attachment Seed Rate Charts
(Pounds per acre)
Checking Volumetric Seeding Rate
The seed charts are based on cleaned seed and
11L x 15 rib implement tires and 13 x 5.00-6
contact drive wheel tires. Factors including for-
eign material, seed treatment, seed size, seed
weight, field conditions and tire pressure will af-
fect seeding rate. Set and check the seeding
rate, then readjust the rate as necessary.
3.
Record the weight of an empty container
large enough to hold seed metered from
three cups for one acre.
4.
Place several pounds of seed over three
seed cups on an outside end of the small
seeds box. Raise drill off the ground.
