Planter Leveling
Crushing Hazard
To avoid sudden hitch failure risk, always have two
bolts through the two holes on both hitch and
tongue. Never rely on a single bolt. Failure to do so
could cause the hitch to fail.
During initial setup and periodically throughout the
season, check that the planter runs level. When
planting, the top of the main frame should be parallel
to the ground.
To level the planter, the distance from the bottom of
the mainframe tube (1) to the ground, must be 26 in
(66 cm) with the planter lowered into planting
position.
With the openers in the ground, this frame height
normally requires a hitch height (2) of 18.25 in (46
cm) measured from the bottom of the tongue to the
ground.
To achieve the correct hitch height, remove the two
hitch bolts and move the planter hitch to another hole
location. Make sure to assemble the hitch parts and
safety chain according to “
Planter Hitches ” on
page 10.
Wheel Adjustment for Leveling
If the target tool bar height cannot be achieved with
the frame level, relocate the wheel axles in the arms.
To do so:
1. Block up the frame to remove weight from the
tires.
2. Remove the bolts (1) securing the ground tire
assembly to the unit.
3. Move the wheel assembly to one of the other
holes and secure the assembly using the
previously removed bolt.

Speed Calibration
Calibrate the speed sensor the first time the planter is
operated in the field (with or without planting).
See
the console manual for instructions for your seed
monitoring system.
Cross-check the monitor speed reading with the
tractor speedometer.
Speed Sensor
The seed monitoring system uses a pickup wheel for
measuring planter ground speed. The speed sensor
should be set at 1/16 to 1/8 inch (1.6 to 3.2 mm) from
the pickup wheel.
