CONTACT DRIVE WHEEL SPRING
ADJUSTMENT
There are two down pressure springs on
each contact drive wheel. The down
pressure is factory pre-set and should need
no further adjustment.
The spring tension is set leaving 2 ¼"
between the spring plug and the bolt head.
TIRE SCRAPER
Due to the clearance between the wheel
assembly and the transport tire when a
planter is equipped with the 20" transport
tire, a tire scrapper should always be used.
This will help prevent a build-up of dirt/mud
between the wheel arm assembly and the
tire. Adjust the scrapper so it does not
contact the tire.
RIDGE PLANTING
For ridge planting mount the 20" tires in the
lower rear holes in the ground drive wheel
arm to raise the bar height 3". Mount the
contact drive wheel arm and springs in the
lower set of mounting holes in the wheel
module mount and raise the hitch height to
maintain fore and aft levelness.
TRANSMISSION ADJUSTMENT
Planting population rate changes are made
at the end mounted transmission. The
planter is designed to allow simple, rapid
changes in sprockets to obtain the desired
planting population. By removing the lynch
pins on the hexagon shafts, sprockets can
be interchanged with those from the sprocket
storage rod bolted to the transmission.
Chain tension is controlled by a spring-
loaded dual sprocket idler. The idler
assembly is adjusted with a ratchet arm. This
arm has a release position to remove spring
tension for replacing sprockets. The amount
of spring tension on the chain can be
controlled by the ratchet arm.
The planting rate chart on the following
pages of this section will aid you in selecting
the correct sprocket combinations.
