• Parking brake is not engaged, OR
• Motion control handles are not in the NEUTRAL
position, OR
• Operator is not on the seat.

Test 3 — Engine should SHUT OFF if:
• Operator rises off seat with PTO engaged, OR
• Operator rises off seat with parking brake disen-
gaged, OR
• Operator moves the control levers out of the neutral
position with the parking brake engaged.
Test 4 — Blade Brake Check
Mower blades and mower drive belt should come to a
complete stop within seven seconds after electric PTO

NOTE: Once the engine has stopped, PTO switch must
be turned off, parking brake must be engaged, and the
motion control handles must be locked in the NEUTRAL
position after the operator returns to the seat in order to
start the engine.
