Setting the Height-of-Cut 1 The height-of-cut lever (deck lift) is used to raise and lower the mower to the desired cutting height. 3 1505 Figure 7 1. Wheel 2. Wheel bracket 1. The cutting height may be set in one of seven positions from approximately 1 to 4 in. (25 to 102 mm). 2. Pull on the height-of-cut lever (deck lift) and move it to the desired position (Fig. 6). 3.
The Safety Interlock System 5. Move the throttle lever to Choke (Fig. 10). Note: An engine that has been running and is warm may not require step 5. Understanding the Safety Interlock System 1 The safety interlock system is designed to prevent the engine from starting unless: 2 • You are sitting on the seat. • The clutch/brake pedal is depressed. 3 • The PTO is Disengaged. The safety system is designed to stop the engine if: m–1859 • You rise from the seat when the clutch/brake pedal is released.
Testing the Safety System 1. Engage the PTO. 2. Insert the KeyChoice key into the switch (Fig. 12). Caution If safety interlock switches are disconnected or damaged the machine could operate unexpectedly, causing personal injury. • Do not tamper with the interlock switches. • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine. • Replace switches every two years regardless of whether they are operating properly or not.
Driving Forward or Backward Caution The throttle control regulates the engine speed as measured in RPM (revolutions per minute). Children or bystanders may be injured if they move or attempt to operate the tractor while it is unattended. To go forward or backward, depress the clutch/brake pedal. Move the ground speed selector to the desired forward speed or reverse. As you slowly release the pedal, the machine will begin to move. Steer the machine with the steering wheel.
Installing the Discharge Cover Using the Mower for the First Time To convert from a side discharge to a mulching mower, install the discharge cover into the opening at the side of the mower. Cut the grass slightly longer than normal to ensure the cutting height of the mower does not scalp any uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than 6 in.
Keep the Underside of the Mower Clean Blade Maintenance Use the washout port to clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory. Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease.
Caution If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition and disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Servicing the Engine Oil 2 1 Check the oil level daily or after every 8 hours. Change the oil after the first 5 operating hours and every 50 operating hours thereafter.
4. Place a pan below the drain plug and remove it (Fig. 16). 4. Install the replacement oil filter to the filter adapter. Turn the oil filter clockwise until the rubber gasket contacts the filter adapter; then tighten the filter an additional 1/2 to 3/4 turn (Fig. 17). 1 5. Slowly pour approximately 80% of the specified amount of oil into the fill hole (Fig. 16). Check the oil level; refer to Checking the Oil Level, page 20, steps 4 and 5. Servicing the Battery Warning 2 Figure 16 1.
Checking the Electrolyte Level Warning 1. Tip the seat forward to see the battery. Incorrect battery cable routing could damage the tractor and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. 2. Look at the side of the battery. The electrolyte must be up to the Upper line (Fig. 19). Do not allow the electrolyte to fall below the Lower line (Fig. 19). 3.
Important Do not overfill the battery because electrolyte (sulfuric acid) can cause severe corrosion and damage to the chassis. 5. Install the battery in the tractor and connect the battery cables; refer to Installing the Battery, page 22. 5. Wait five to ten minutes after filling the battery cells. Add distilled water, if necessary, until the electrolyte level is up to the Upper line (Fig. 19) on the battery case.
Greasing and Lubrication 3. Clean around the air cleaner to prevent dirt from getting into the engine and causing damage. Pull up on the air cleaner cover handle and rotate it toward the engine (Fig. 23). Remove the air cleaner cover. Grease the machine after every 25 operating hours or once a year, whichever occurs first. Grease more frequently when operating conditions are extremely dusty or sandy. 2 Grease Type: General-purpose grease 1 How to Grease 1.
