Safety Interlock System; Starting The Engine - Urrea TGZ950 Manual De Usuario

• Be careful when operating near roadways. Stop the tractor
motion and wait for vehicles to pass before operating along
the road.
• Do not operate the tractor with the mower deck removed.
Removal of the deck will change the balance of the tractor, and
could contribute to a tractor rollover.
• Avoid operation on traction surfaces that are unstable; use
extreme caution if the surface is slippery.
• Slow down before turning and come to a complete stop be-
fore any zero turn maneuver.
• Do not stop the tractor or park the tractor over combustible
materials such as dry grass, leaves, debris, etc.
• Do not fill the fuel tank when the engine is running or while
the engine is hot. Allow the engine several minutes to cool be-
fore refueling. Tighten the fuel cap securely.
BEFORE OPERATING YOUR TRACTOR
• Before you operate the tractor, study this manual carefully to
familiarize yourself with the operation of all the instruments
and controls. It has been prepared to help you operate and
maintain your tractor efficiently.
• This engine is certified to operate only on clean, fresh, un-
leaded 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 gaso-
line left over from the previous season, to minimize gum de-
posits 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 ap-
proved 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 autho-
rized Cub Cadet Dealer.
• The safety interlock system prevents the engine from crank-
ing or starting unless the RH and LH drive control levers are
moved fully outward in the neutral position and the PTO is dis-
engaged.
• The safety interlock system will shut off the engine if the op-
erator leaves the seat with the PTO engaged.
NOTE: The PTO switch must be moved to the "STOP" position
to restart the engine.

• The safety interlock system will shut off the PTO and the
mower blades will stop if both drive control levers are moved
into the reverse position. To re-engage the PTO, the levers must
be in the neutral or forward drive position and the PTO switch
must be placed in the OFF (disengaged) position and then re-
turned to the ON (engaged) position.

STARTING THE ENGINE

WARNING: This tractor is equipped with a safety interlock
system designed for the protection of the operator. Do not op-
erate the tractor if any part of the interlock system is malfunc-
tioning. Periodically check the functions of the interlock system
for proper operation.
WARNING: For personal safety, the operator must be sitting
in the tractor seat when starting the engine.
1. Operator must be sitting in the tractor seat with the control
levers fully outward in neutral (parking brake on).
2. Make certain the PTO switch is in the disengaged (down)
position. Refer to Figure 9.

· Move the choke control or throttle/choke control into the full
choke position.
NOTE: If the engine is warmed up, it may not be necessary to
place the choke or throttle/choke control in the choke position.
· Move the throttle control to midway between its slow
and fast positions on models with a separate choke control.
· Insert the key into the ignition switch and turn the key clock-
wise to the start position
starts; however, do not crank the engine continuously for more
than 5 seconds at a time. If the engine does not start within this
time, turn the key to the stop position
seconds to allow the engine's starter motor to cool. Try again
after waiting. If after a few attempts the engine fails to start,
do not keep trying to start it with the choke closed as this will
cause flooding and make starting more difficult.
· As the engine warms up, gradually pull the throttle/choke
control lever rearward past the choke detent position or slowly
disengage the choke on models with a separate choke. Do not
use the choke position to enrich the fuel mixture, except as
necessary to start the engine.
