When transporting the machine, remove the whole set of the work equipment. When installing again, adjust the
tension of the center brace.
If the adjustment is not performed, the bushing at the mounting portion of the blade and straight frame comes
off, and soil and sand enter and cause premature wear or damage of the bushing. Adjust as follows.

equipment lock lever.
