4.1 DAILY INSPECTION________________________________________________________
1. Perform a visual inspection of the entire unit, look for
signs of wear, loose hardware, and missing or damaged
components. Check for fuel or oil leaks to ensure con-
nections are tight and hoses and tubes are in good con-
dition.
2. Check the fuel supply, radiator coolant level, crankcase
oil and air cleaner indicator. All fluids must be at the full
level mark with engine cold.
3. Make sure all mowers are adjusted to the same cutting
height.
4. Visually check tires for proper inflation.
5. Test the operator back-up system.
4.2 Operator Back-Up System __________________________________________________
1. The operator back-up system prevents the engine from
starting unless the parking brake is engaged, the trac-
tion pedal is in neutral and the mower switch is “OFF”.
The system also stops the engine if the operator leaves
the seat with the mower switch “ON”, traction pedal out
of NEUTRAL, or parking brake “DISENGAGED”.

operator back-up system is functioning properly. Stop
the test and have the system inspected and repaired if
any of the tests
fail as listed below:
●
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.
3. Refer to the chart below for each test and follow the
check (
✔

between each test.
