To help avoid injury: Perform all service with tractor off and parking brake set, unless otherwise
instructed. If attachment must be raised for service, only raise it enough to clear the ground.
Note: If new bits and deflectors are installed, it is normal for bits to hit the deflectors until a
portion of the deflector is worn away.
