SAFETY INTERLOCK SYSTEM
Check Safety Interlock System
Test the safety interlock system at each operation. If the
system does not function properly, do not operate the unit
until repairs are made.
The engine will only start with the PTO disengaged, the
speed control levers in neutral and the parking brake on.
To test:
1. With engine off, set controls as listed in line A of the
table below and try to start the engine.
IMPORTANT: If the system does not function properly, do
not operate the unit until repairs are made.
2. Repeat step 1 for lines B-E of the table.
*
Test the left and right operator presence controls
separately.
3. With engine running, set controls as listed in line A of
the table below and check the result.
IMPORTANT: If the system does not function properly, do
not operate the unit until repairs are made.
4. Repeat step 3 for lines B-E of the table.
*Perform this test with PTO properly engaged.

off AND at least one operator presence control is engaged.
PTO should disengage when BOTH operator presence con-
trols are released.
Operator Presence Control
The operator presence control levers must be depressed to
operate the PTO. When the PTO is engaged, releasing the
operator presence control levers stops the mower blades.
