level using the following instructions:

blade-control switch.
2. Set the parking brake, stop the engine, remove the key,
and wait for all moving parts to stop before leaving the
operating position.
3. Set the height-of-cut lever to middle position.
Note: Check and adjust the side-to-side blade level
if you have not checked the setting; refer to
from Side to Side (page
