interlock system designed for the protection of

the operator. Do not operate the tractor if any

part of the interlock system is malfunctioning.

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 push the choke 

knob downward to open the choke. Do not use the

choke to enrich the fuel mixture, except as necessary to

start the engine.

Allow the engine to run for a few minutes at mid 

throttle before putting the engine under load.

Cold Weather Starting

When starting the engine at temperatures near or below

freezing, ensure the correct viscosity motor oil is used

in the engine and the battery is fully charged. Start the

engine as follows:

Use fresh winter grade fuel. Winter grade gasoline 

has higher volatility to improve starting. Do not use

gasoline left over from summer.

area is well ventilated, wear gloves and eye

protection, and avoid sparks or flames near

the battery.

If the battery charge is not sufficient to crank the engine,

recharge the battery. If a battery charger is unavailable

and the tractor must be started, the aid of a booster

battery will be necessary. Connect the booster battery as

follows:
