• This engine is certified to operate only on clean,
fresh, unleaded regular gasoline. For best results,
fill the fuel tank with only clean, fresh, unleaded
gasoline with a pump sticker octane rating of 87
or higher.
• Unleaded gasoline is recommended because it
leaves less combustion chamber deposits and
reduces harmful exhaust emissions. Leaded
gasoline is not recommended and must not be
used where exhaust emissions are regulated.
NOTE: Purchase gasoline in small quantities. Do not
use gasoline left over from the previous season, to
minimize gum deposits in the fuel system.
• Gasohol (up to 10% ethyl alcohol, 90% unleaded
gasoline by volume) is an approved fuel. Other
gasoline/alcohol blends are not approved.
• Methyl Tertiary Butyl Ether (MTBE) and unleaded
gasoline blends (up to a maximum of 15% MTBE
by volume) are approved fuels. Other gasoline/
ether blends are not approved.
• Check the engine oil level.
• Clean the air cleaner element if necessary.
• Check the tire inflation pressures.
• Adjust the seat for operator’s maximum comfort,
visibility and for maintaining complete control of
the tractor.
SAFETY INTERLOCK SYSTEM
This tractor is equipped with a safety interlock system
for the protection of the operator. If the interlock
system should ever malfunction, do not operate the
tractor. Contact your authorized Cub Cadet Dealer.
• The safety interlock system prevents the engine
from cranking or starting unless the RH and LH
drive control levers are moved fully outward in the
neutral position, the parking brake is engaged,
and the PTO is disengaged.
• To avoid sudden movement when disengaging
the parking brake, the safety interlock system will
shut off the engine if the RH and/or LH drive
control levers are moved to a position other than
the fully out in neutral position when the parking
brake is engaged
• The safety interlock system will shut off the
engine if the operator leaves the seat before
engaging the parking brake.
• The safety interlock system will shut off the
engine if the operator leaves the seat with the
PTO engaged, regardless of whether the parking
brake is engaged.
NOTE: The PTO switch must be moved to the
“OFF” position to restart the engine.
• The safety interlock system will shut off the PTO
and the mower blades will stop if both drive con-
trol levers are moved into the reverse position.
The PTO will re-engage when one or both of the
levers are moved back to the neutral or forward
position.
