Pull-Type Hitch Leveling
Refer to Figure 20 (bottom of page)
With new coulter blades at 4 inch depth and coulter
applicator tips 1 inch above ground, the tool bar height is:
25 inches (63.5 cm)
and normally requires a pull-type hitch height of:
16.75 inches (42.5 cm)
measured from the bottom of the tongue to the ground.
Refer to Figure 19
Sudden Hitch Slump or Failure Risks:
Always have two bolts through two holes on both hitch and
tongue. Never rely on a single bolt.
To obtain the correct height, and a level tongue, remove
the two hitch bolts
, and reposition the fertilizer
applicator hitch on the tongue.
The hitch can be inverted in the tongue for extreme
height changes.
