causing personal injury.
Do not tamper with the interlock switches.
Check the operation of the interlock switches

released while the speed control is out of neutral
position and/or the mower is engaged.
The speed control lever is shifted out of neutral
without holding OPC levers.
The blade control switch (PTO) is pulled on without
