Seed Depth Adjustment
Adjust the seed depth by turning the knob(A). Turning
the knob changes the height of the depth gauge wheels
in relation to the disc openers. One full revolution of the
adjustment knob (A) is equal to approximately 1/8th inch
of adjustment. A depth gauge on both sides of the unit
(B), indicates the set depth. Seed depth ranges is from
1/8" to 3" deep. Be sure to set all of the row units on the
planter at the same adjustment. Set a depth that is best
suited for your soil conditions.
Depth Gauge Wheels
The depth gauge wheels use an equalizing rocker arm
to achieve uniform depth control of the disc openers.
The gauge wheels are independent of each other for a
consistent ride through the field.
In order for the disc openers to remain properly clean and
free of soil build-up, make sure the flange of the gauge
wheel is just touching the disc. To double-check this,
raise the unit and manually rotate disc openers the gauge
wheels should also rotate freely without restriction.
Adjust gauge wheel spacing by moving the washers from
one side of the articulating arm to the other. Use a high
quality SAE grease to lubricate the gauge wheel arms.
Gauge wheel arms should be greased daily, more often
in extreme conditions.

Drive Chain
The drive chains have a spring-loaded tensioner. The
chain may need to shorten or replace the chain if wear
stretches the chain and reduces spring tension.
Periodically check the pivot point of the chain idlers to
ensure they rotate freely. Use a chain lubricant spray
daily, or as needed. Dry moly is the recommended chain
lubricant.
Double Disc Openers
Double Disc Openers
The heavy-duty double disc openers are very durable
and mounted on sealed roller bearings. Their function
is to slice the soil, and open a straight seed trench. An
interchangeable firming point attached to the frame and
positioned ahead of the seed tube also acts as an inner
disc scraper.
A disc scraper is mounted to the outside of each disc.
Adjust the pressure of the scrapers by tightening or
loosening the bolts.
Checking Pinch Point
The double disc openers should have a pinch point length
between 1.5" to 2.25". The pinch point is adjusted by

adding or removing shims to the spindle bolt. The spindle
bolts should be torqued to 100 ft-lbs.
Replacing Double Discs
The double disc openers need replaced when the disc
diameter measures 14.5" or less, or a 1.5" pinch point
cannot be achieved.
