General Operating Safety
Before first time operation:
• Be sure to read all information in the Safety and
Operation sections before attempting to operate this
unit.
• Become familiar with all of the controls and how to stop
the unit.
• Drive in an open area without mowing to become
accustomed to the unit.

Checks Before Starting

• Check that crankcase is filled to full mark on the engine
oil dipstick (B, Figure 3). See the engine Operator's
Manual for instructions and oil recommendations.
• Fill the fuel tank (A) with fresh fuel. Refer to engine
manual for fuel recommendations.
• Make sure all nuts, bolts, screws and pins are in place
and tight.
• Check the tire pressures. See Check Tire Pressures.
• Check the hydraulic oil tank (C) and make sure that the
oil level is up to the FULL COLD mark.
• Adjust the height of the mower deck to the desired
position. See Mowing Height Adjustment.
WARNING
• Before leaving the operator's position for any reason,
engage the parking brake, disengage the PTO, stop the
engine and remove the key.
• To reduce fire hazard, keep the engine, unit and mower
free of grass, leaves and excess grease. Do NOT stop
or park tractor over dry leaves, grass or combustible
materials.
• Gasoline is highly flammable and must be handled with
care. Never fill the tank when the engine is still hot from
recent operation. Do NOT allow open flame, smoking or
matches in the area. Avoid over-filling and wipe up any
spills.
WARNING
Operating on steep slopes can be dangerous.
• Select slow ground speed before driving onto a slope.
• Mow across the face of slopes, not up and down, use
caution when changing directions and DO NOT START
OR STOP ON A SLOPE.

Starting the Engine

choking.

ALL controls.
3. Insert the key into the ignition switch and turn it to RUN.
4. Grasp the recoil starter handle and pull slowly until
resistance is felt and then pull rapidly. (You may have to
pull several times before the engine starts. If the engine
fails to start within a reasonable number of attempts,
discontinue and check engine manual for further
instructions.
4. After the engine starts, gradually open the choke (push
knob down fully). Reduce to half throttle speed and
allow to warm up.
Warm up the engine by running it for at least a minute
before engaging the PTO switch or driving the unit.
5. After warming the engine, ALWAYS operate
the unit at FULL THROTTLE when mowing.
In the event of an emergency the engine can be
stopped by simply turning the ignition switch
