Disengage Meter
Refer to Figure 81
7.
Uncouple meter drives for the locked-up rows. Pull
shaft out and park pin in shallow detents.
Equipment Damage Risk:
Do not disable meters by removing them or chain drive dam-
age will occur.
8. Shut off Y-tube port for the current row unit.
9. Repeat for all rows needing lock-up.
10. Reset marker extension (page 167).
11. Reset monitor active row pattern and row spacing to
avoid nuisance alarms.
Equipment Damage Risk:
Do not pin the row unit while it is in the lowered position. If
the pin is inserted below the parallel arm, unit damage will
occur when planting begins.
Unit-Mount Cleaner Adjustments
Refer to Figure 82 and Figure 83
Optional Martin row cleaners are unit-mounted, using:
UMRC: Unit-Mount Row Cleaner (stand-alone), or
UMC-RC: Unit-Mount Coulter RC (on coulter bracket,
with or without a coulter disk present).
There are two adjustments:
1. Wheel placement (forward or aft mounting hole, for
more or less aggressive cleaning), and
2. Wheel height, adjusted by a stop. Cleaner arms
float. The stop only sets the lowest position.
In UMRC mount, a pinned cross-tube on the mount
adjusts the depth. In UMC-RC (coulter) mount, a sliding
down-stop block
adjusts how close to the ground the
row cleaners operate.
The row cleaner needs to be adjusted for your condi-
tions, crop changes, and as coulters and openers wear.
Ideally, cleaners contact only the trash, and do not dis-
turb the soil. If allowed to “dig”, row cleaners can reduce
seed coverage.
Suggested initial depth is tine tips at ground level.
Make the adjustment with the planter raised. Install
lift-assist cylinder locks. Also check bolt
tightness prior
to each planting session, to avoid down-stop slippage.
