How do I use the Reverse Caution Mode on the TB30R?

Turn the key from the NORMAL MOWING (Green) position to the REVERSE CAUTION MODE (Yellow) position on the key switch module, then press the orange triangular REVERSE PUSH BUTTON at the top right corner of the module — the red indicator light will illuminate when activated. Once active, the tractor can be driven in reverse with the cutting blade (PTO) engaged. Always look down and behind while backing, and do not use this mode when children or others are nearby.
