 Replace blade if it is bent, cracked, or damaged in any way.
An unbalanced blade causes vibration that could damage
the motor drive unit or cause personal injury. Sharpen a
dull blade equally at each end to maintain the balance.
Clean the blade thoroughly and check its balance by
supporting it horizontally on a thin nail through its center
hole. The nail should be in a horizontal position. If either
end of the blade rotates downward, remove some metal
from the heavy lower end until the blade is balanced. It
is balanced when neither end drops.
 The side discharge chute is a spring-loaded guard that
covers the side discharge opening on the mower deck and
deflects grass clippings and debris away from the operator.
Always ensure that the motor is off and the blades have
stopped moving before inspecting, moving, cleaning, or
performing maintenance on the side discharge chute.
 Always use safety protective devices. Do not operate
the mower without the side discharge chute in place
and working properly. Mulch cover should be correctly
installed and working properly during mulching operation
and bagger kit should be correctly installed and working
properly during bagging operation.
 Never interfere with the intended function of a safety de-
vice or reduce the protection provided by a safety device.
Check their proper operation regularly.
 Never tamper with safety devices. Check for proper op-
eration regularly.
 Follow manufacturer's instructions for proper operation and
installation of accessories. Only use accessories approved
by the manufacturer. The use of other accessories may
increase the risk of injury.
 Clear the work area before each use. Remove all objects
such as rocks, sticks, metal, wire, bones, toys, fallen tree
limbs, tree nuts, or other objects which can be thrown by
the blade.
 Objects struck by the lawn mower blades can cause
severe injuries to persons. The lawn should always be
carefully examined and cleared of all objects prior to each
mowing.
 If the lawn mower strikes a foreign object, follow these
steps:
• Stop the lawn mower, set the parking brake, wait until
the blades come to a complete stop, and then remove
start key.
• Thoroughly inspect the mower for any damage.
• Replace the blade if it is damaged in any way. Repair
any damage before restarting and continuing to oper-
ate the mower.
 Slopes are a major factor related to loss of control and
tip-over accidents, which can result in severe injury or
death. Operation on all slopes requires extra caution. If
you cannot back up the slope or if you feel uneasy on it,
do not mow it. Do not reverse down a slope. Never use
on steep slopes greater than 15°.
IMPORTANT SAFETY INSTRUCTIONS
• Never attempt to ride on a steep slope or
mow a slope that is greater than 15°. To
determine the angle of your slope, use the
Slope Guide at the back of this manual.
• Mow up and down slopes, not across.
• Watch for holes, ruts, bumps, rocks, or other hidden
objects. Uneven terrain could overturn the machine.
Tall grass can hide obstacles.
• Use a slow speed so you will not have to stop suddenly
or accidentally accelerate while on a slope.
• Do not mow on wet grass. Tires may lose traction and
you may lose control.
• Always keep the drive levers in the forward position
when going down slopes. Do not move to neutral and
coast downhill, which may cause you to lose control
of the mower.
• Avoid starting, stopping, or turning on a slope. If the
tires lose traction, disengage the blades and proceed
slowly straight down the slope.
• Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction, which
could cause the machine to roll over.
• Use extra care while operating machine with baggers
or other attachments; they can affect the stability of
the machine. Do not use on steep slopes greater than
15°.
• Do not try to stabilize the machine by putting your foot
on the ground.
• Stay at least two mowing widths (7 feet) away from any
ditches, drop-offs, or water. Front caster wheels can
rotate when mower is stopped, even with the brake
applied, and cause the mower to go over the edge or
into the water and result in death or serious personal
injury.
 Never direct discharged material toward anyone. Plan
your mowing pattern to avoid discharge of material toward
bystanders, roads, sidewalks, windows, cars, and the
like. Also, avoid discharging material against a wall or
obstruction, which may cause the material to ricochet
back toward the operator.
 Stop the blade when crossing gravel surfaces to avoid
discharging gravel and rocks and drive the mower slowly
and carefully to avoid loss of control.
 Use extra care when approaching blind corners, shrubs,
trees, or other objects that may block your view.
 Never make any adjustments or repairs with the motor
running and/or blades moving. Turn off power switch and
remove key.
