The height-of-cut foot lever allows the operator to use their leg to assist in lowering and raising the deck from the seated position (Figure 4). Push the lever forward with your foot to raise the cutting deck.

Allow the lever to move rearward to lower the cutting deck to the cut height that has been set.

Hour Meter

S-Series Units Only

Located on control panel.

The hour meter records the number of hours when the operator is in the seat and the ignition switch is in the “ON” position.


Recommended Gasoline

Fill fuel tank on level ground. See Fuel

Recommendations in the Specifications section for additional gasoline information.

Do Not add oil to gasoline.

Do Not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.




In certain conditions gasoline is extremely flammable and vapors are explosive.

A fire or explosion from gasoline can burn you, others, and cause property damage.

• Fill the fuel tank outdoors on level ground, in an open area, when the engine is cold. Wipe up any gasoline that spills.

• Never refill the fuel tank or drain the machine indoors or inside an enclosed trailer.

• Do Not fill the fuel tank completely full. Add gasoline to the fuel tank until the body of the tank is full but fuel does not fill the neck of the tank. This empty space in the tank allows gasoline to expand.

• Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by spark.

• Store gasoline in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of gasoline.

• Do Not operate without entire exhaust system in place and in proper working condition.


In certain conditions during fueling, static electricity can be released causing a spark which can ignite gasoline vapors. A fire or explosion from gasoline can burn you and others and cause property damage.

• Always place gasoline containers on the ground away from your vehicle before filling.

• Do Not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

• When practical, remove gas-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

• If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.

• If a gasoline dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do Not use a nozzle lock open device.


Gasoline is harmful or fatal if swallowed.

Long-term exposure to vapors has caused cancer in laboratory animals. Failure to use caution may cause serious injury or illness.

• Avoid prolonged breathing of vapors.

• Keep face away from nozzle and gas tank/container opening.

• Keep away from eyes and skin.

• Never siphon by mouth.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

• Keeps gasoline fresh during storage of 30 days or less. For longer storage it is recommended that the fuel tank be drained.

• Cleans the engine while it runs.

• Eliminates gum-like varnish buildup in the fuel system, which causes hard starting Add the
