Leveling Planter
Refer to Figure 10
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 bottom of the
mainframe tube to the ground, must be:
26 inches (66 cm)
with the planter lowered into planting position.
With the openers in the ground, this tool bar height
normally requires a hitch height
of:
14
1 ⁄
2
inches (36.8 cm)
measured from the bottom of the tongue to the ground.
Refer to Figure 11 (showing one of two hitch bolts)
To obtain the correct height, remove the two hitch
bolts
, and reposition the planter hitch on the tongue.
Sudden Hitch Slump or Failure Risks:
Always have two bolts through two holes on both hitch and
tongue. Never rely on a single bolt.
The hitch can be inverted in the tongue for extreme
height changes.
Wheel Adjustment for Leveling
Refer to Figure 12
If the target tool bar height cannot be achieved with the
frame level, an adjustment can be made by relocating
the wheel axles in the arms. This lowers the planter by
about 2 inches (5.1cm).
Block up the frame to remove weight from tires. Remove
bolts
, located in lower holes, securing transport
ground tire assembly to unit. Move wheel assembly and
secure assembly to upper hole
using previously
removed bolt.
