Seed Rate Adjustment
NOTE
Wrenches used for adjustment are stored on a pin at the
back of the transmission.
• To Prevent damage to seed meters, do not
apply excessive force to adjusting nuts. This
is especially important when closing meters
as seed in flutes can be pinched between
cut-off and washer in seed cup.
• Do not close meters more than 1/8" when
there is seed in the meters without rotating
the seed shaft to prevent damage to the
rotating washers and retainer rings in the
seed meters.
• Do not attempt to open meters more than 1".
(Feed rolls could become disengaged from
washer in the seed cup.)
Seed rate chart is located inside the seed box cover and
in this manual. See Table 3-9. It should be used as a
general guide only. Because of seed variation, a more
accurate rate can be determined by calibrating the
seeder as shown in the chart.
Seed rate is set by adjusting the micro-meter on the right
side. See Figure 3-5.
• To increase the rate of seeding, loosen the large
locknut (see NOTE above "WARNING" notice) on
inside of the bearing and turn the outer seed rate
adjusting nut to the desired higher number setting,
then tighten the large inner locknut.
• To decrease the rate of seeding, loosen the inner
seed rate adjusting nut and set the outer adjusting
nut to the new desired lower number position; then
tighten the large inner locknut. See Figure 3-7.
Seed cups discharge to the front of the machine to aid
the operator in determining proper operation.

A 1/4-20 x 2-1/4" grade 5 bolt connects the 6 tooth #550
roller chain sprocket to the front transmission shaft. This
bolt must be removed for calibration.
The bolt can also be removed if it is desired to use the
seeder as a pulverizer only. See Figure 3-6.
NOTE
Acre meter will not register when bolt is removed.
