until they stop allows the unit to move under
hydraulic power. The levers must be in this position
and torqued to 10ft/lbs during operation of the
mower. Rotating the levers counter-clockwise
allows the mower to be moved by hand (free-
wheeling).

4.2 SAFETY INTERLOCK SYSTEM
The mower is equipped with a safety interlock system
that prevents the engine from starting unless the deck
drive is disengaged, the parking brake is engaged, the
steering control levers are in the neutral position and the
operator is in the seat. The interlock system shuts off
the engine if the operator leaves the seat with the
steering control levers not in the neutral position and/or
the cutter blades engaged and the parking brake not
engaged.
WARNING:
Never operate the mower with the interlock
system disconnected or malfunctioning. Do
not disengage or bypass any switch; injury to
yourself and others or property damage could
result.
