cutting deck. Allow the pedal to move rearward to
lower the cutting deck to the cut height that has been
set.
Transport Lock
Located on the height of cut adjustment plates to the
right of the parking brake.
Position in the transport latching position to
automatically latch the cutting deck when raised to
the transport position (see item 1 in Figure 11).
In the non-latching position, the deck will

Pre-Start
Fill fuel tank. For best results use only clean, fresh
regular grade unleaded gasoline with an octane rating
of 87 or higher.
Do Not add oil to gasoline.
Do Not overfill fuel tank. Never fill the fuel tank so
that the fuel level rises above a level that is 1/2 inch
(13 mm) below the bottom of the filler neck to allow
for fuel expansion and prevent fuel spillage.
Make sure you understand the controls, their
locations, their functions, and their safety
requirements.
Refer to the Maintenance section and perform all the
necessary inspection and maintenance steps.

tabs interlocking as shown in Figure 12 to lock
the roll bar in the raised, operate position.
2. Apply forward pressure to the upper hoop of the
roll bar.
3. Pull the knob and rotate 90° to hold in the
unlatched position to lower the roll bar.
4. To return to the operate position, raise the roll
bar, and then rotate knobs 90° so that the tabs
interlock partially. Apply forward pressure to the
roll bar upper hoop and observe that the knobs
return to the completely latched position.
