SECTION 7: OPERATION

Safety Interlock Switches

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 brake pedal is fully

depressed, and the PTO is “OFF”.

• The safety interlock system will

automatically shut off the engine if

the operator leaves the seat before

engaging the brake lock.

• The safety interlock system will

automatically shut off the engine if

the operator leaves the seat with the

PTO “ON”, regardless of whether

the brake lock is engaged. The PTO

switch must be “OFF” to restart the

engine.

• The safety interlock system will

automatically shut off the PTO if the

reverse control pedal is depressed

with the PTO “ON”.

Fueling The Tractor

NOTE:Some fuels, called oxygen-

ated or reformulated gasolines, are

gasoline blended with alcohols or

ethers. Excessive amounts of these

blends can damage the fuel system or

cause performance problems. Do not

use gasoline which contains Metha-

nol. If any undesirable operating

symptoms occur, use gasoline with a

lower percentage of alcohol or ether.

Do not fill the fuel tank when the

engine is running or while the engine

is hot. Tighten the fuel cap securely.

This engine is certified to operate on

unleaded gasoline. Fill the fuel tank

with only clean, fresh, unleaded gaso-

line with a minimum of 85 octane. Do

not mix oil with gasoline. Purchase

fuel in a quantity that can be used

within 30 days to assure fuel fresh-

ness. In countries other than the

U.S.A., leaded gasoline may be used

if it is commercially available and

unleaded is not available.

The fuel fill point is located on the

fender to the left of the seat. Unscrew

the fuel cap and fill tank from an

approved gasoline container.

Starting The Engine

• Operator must be sitting in the

tractor seat.

• Push choke lever to the full choke

position. Less choking may be

necessary due to variations in

temperature, grade of fuel, etc. Little

or no choking will be needed when

the engine is warm.

• Place the throttle midway between

the “SLOW” and “FAST” position.

• Make sure the PTO switch is in the

“OFF” position.

• Fully depress the brake pedal.

• Turn the ignition key clockwise to

the “START” position and release it

as soon as the engine starts;

however, do not crank the engine

continuously for more than 10

seconds at a time. If the engine

does not start within this time, turn

the key to “OFF” and wait a minute

to allow the engine’s starter motor to

cool. Try again after waiting.

• After the engine starts, slowly

release the brake pedal. As the

engine warms up, gradually pull the

choke lever all the way back. Do not

use the choke to enrich the fuel

mixture, except when necessary to

start the engine.

Stopping The Engine

NOTE: Remove the key from the

ignition switch to prevent accidental

starting or battery discharge if the

equipment is left unattended.
