CONTROLS
Choke Control
The choke control is used for cold starts to
provide the engine with a richer fuel mixture.
For cold starts, pull the control up.
Service Meter
The service meter displays the total operating
time.
NOTE: The service meter operates (clocks hours)
only when the engine is running. Be sure to turn
the key off when the mower is not in use, to
prevent meter hours from accumulating.
Blade Switch
To engage the mower deck, pull the knob out;
mower blades are disengaged when the knob is
pressed down.

Park Brake
The park brake is found on the right of the
machine. Pull the lever back to engage the brake
and push forward to release it.
IMPORTANT The machine must stand still
when engaging the park brake. Release the
park brake before moving the mower.
Hydraulic Pump Bypass Valves
Bypass valves are used to release the system so
the machine may be moved by hand when not
running. See Moving Machine By Hand in the
Maintenance section.
Warning! Bypass linkages are located
close to the engine. To prevent burns, the
engine should be shut off and allowed to cool
before adjusting the valves.
