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 87 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.
