Unit-Mount Cleaner Adjustments
Refer to Figure 63 (depicting a left hand mount - the hole
pattern is identical for the right hand mount)
Optional Martin row cleaners are unit-mounted, using a
coulter mount, with or without a coulter disk present).
There are two adjustments:
1. Wheel placement (3 mounting holes , not visible in
figure, for more or less aggressive cleaning), and
2. Wheel height, adjusted by a stop bolt . Cleaner
arms float. The stop only sets the lowest position.
The row cleaner needs to be adjusted for your
conditions, crop changes, and as coulters and openers
wear. Ideally, cleaners contact only the trash, and do not
disturb the soil. If allowed to “dig”, row cleaners can
reduce seed coverage.
Suggested initial depth is tine tips at ground level.
To adjust coulter depth:
1. Make the adjustment with the planter raised. Install
lift-assist cylinder locks. Drape a tarp over tines to
reduce risk of injury.
2. Determine the present opener depth.
3. Note which stop hole the row cleaner arm is
presently using.
4. Determine which new hole will position the wheel at
the desired height, from the table below.
5. Remove the
