7.2 INTERLOCK SYSTEM ______________________________________________________
The Interlock System prevents the engine from starting unless the parking brake switch is in the ON position, the
traction pedal is in the NEUTRAL position and the PTO switch is in the OFF position. The system stops the engine if
the operator leaves the seat with the PTO switch in the ON position, traction pedal out of the NEUTRAL position or the
parking brake switch in the OFF position.
Do each of these tests to make sure the Interlock System operates correctly. If any of the tests fail, stop the test and
have the system inspected and repaired as shown below:
• The engine does not start during test 1
• The engine does start during tests 2, 3 and 4
• The engine continues to run during tests 5 and 6
Refer to the chart below for each test and follow the check ( 4 ) marks across the chart. Turn off the engine between
each test.
TEST 1: The test shows the normal engine start procedure. The operator is in the seat, parking brake switch is in the
ON position, the traction pedal is in the NEUTRAL position and the PTO switch is in the OFF position. The engine will
start.
TEST 2: The engine must not start if the PTO switch is in the ON position.
TEST 3: The engine must not start if the parking brake switch is in the OFF position.
TEST 4: The engine must not start if the traction pedal is out of the NEUTRAL position.
TEST 5: Start the engine with the normal procedure. Turn on the PTO switch and lift your weight off the seat. The
engine must stop. The cutting unit reels must not rotate after seven (7) seconds.
TEST 6: Start the engine with the normal procedure. Turn off the parking brake switch and lift your weight off the seat.
The engine must stop. The cutting unit reels must not rotate after seven (7) seconds.
WARNING
