is in neutral and the mower switch(es) is “OFF”. The
system also stops the engine if the operator leaves the
seat with the mower switch(es) “ON”, traction pedal out
of NEUTRAL, or parking brake “DISENGAGED”.

Perform each of the following tests to insure the
interlock system is functioning properly. Stop the test
and have the system inspected and repaired if any of
the tests
fail

●
the engine does not start in test 1;
●
the engine does start during tests 2,3 or 4;
●
the engine continues to run during tests 5 or 6.
