Wobble Slot Seed Cup Adjustments and Service
The wobble slot seed cups should be checked
against the slot gauge initially and anytime service
has been performed on the seed shaft or individual
seed cups. Refer to the drawing below for proper
adjustment if repairs have been made.
To verify that all seed cups are set the same on
the shaft, start with all cups fully closed. A slight
crack between the cup halves would be considered
normal tolerance. If any individual cup is not
"zeroed out," open the slot width using the adjust-
ing handle, loosen allen set screws and adjust to
equal others on shaft.
o determine if the gauge is reflecting the correct
seed cup slot width, open the seed cups using the
adjusting handle. Notice that wobble slot halves
are positioned differently on the hex shaft. Identify
a cup that will accept a piece of ½" keystock or
other measuring device comfortably and give solid
contact against each half. It may be necessary to
turn the hex shaft slightly to position the particular
seed cup correctly. Close the slot width firmly
against the measuring device. At the cup next to
the wobble slot adjusting handle, position the
gauge to equal the slot width you have just mea-
sured with the keystock by loosening with a screw-
driver and sliding in or out.
Before removing the keystock, make certain the
bearing located on the adjustment lever is securely
running between the shaft bushings. Adjusting
bushings must be set screwed tightly to shaft with
zero to 1/64" tolerance between the bushing and
bearing. Excess tolerance in this area will allow
the seed shaft to float from right to left, thus
opening and closing wobble slot and varying seed
rate.
Small changes in rate can be made by opening or
closing slot width. To close the slot width with
grain in the box, close the slot down a maximum of
1/8" and then rotate the shaft on turn to clear the
slot. Repeat this process until the desired slot
width is selected.
Seeding rate is affected by seed size, seed
treatments, foreign material, and test weight.
Refer to seed rate charts as guidelines for
desired seeding rates.
