BRAKE OPERATION
If tractor requires more than fi ve (5) feet to
stop at highest speed in high est gear on a
level, dry concrete or paved surface, then
brake must be checked and ad just ed. (See
“TO ADJUST BRAKE” in the Ser vice and
Ad just ments section of this manual).
TIRES
• Maintain proper air pressure in all tires
(See “PROD UCT SPEC I FI CA TIONS”
section of this man ual).
• Keep tires free of gasoline, oil, or insect
control chemi cals which can harm rub-
ber.
• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
NOTE: To seal tire punctures and pre vent
fl at tires due to slow leaks, tire sealant
may be purchased from your local parts
dealer. Tire sealant also pre vents tire dry
rot and corrosion.
OPERATOR PRESENCE SYS TEM AND
REVERSE OPERATION SYSTEM (ROS)

TO SHARPEN BLADE
NOTE: We do not recommend sharp en ing
blade - but if you do, be sure the blade is
balanced.
Care should be taken to keep the blade
balanced. An unbalanced blade will cause
excessive vibration and even tual damage
to mower and engine.
• The blade can be sharpened with a fi le
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
