Side Discharge Mowing Direction The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Alternate mowing direction to keep the grass standing straight. This also helps disperse clippings which enhances decomposition and fertilization. Danger Mow at Correct Intervals Normally, mow every four days. But remember, grass grows at different rates at different times. So to maintain the same cutting height, which is a good practice, mow more often in early spring.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Maintenance Procedure After first use • Change the engine oil. Each use • Check the engine oil level. • Check the safety system. • Clean the mower housing. Every 5 hours • Check the cutting blades. Every 25 hours • • • • • • Every 50 hours • Change the engine oil.2 Every 100 hours • • • • • Clean the cooling system.
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. Oil Type: Detergent oil (API service SF, SG, SH, SJ, or higher) Crankcase Capacity: 48 oz./1-1/2 qt. (1400 cc/1.4 l) when the filter is not changed; 56 oz./1-3/4 qt. (1700 cc/1.7 l) when the filter is changed 1868 Figure 16 1. Oil dipstick 2. Metal end Viscosity: See the table below. USE THESE SAE VISCOSITY OILS 4.
Removing the Foam and Paper Elements 7. Slowly pour approximately 80% of the specified amount of oil, page 20, into the fill hole (Fig. 15). Check the oil level; refer to Checking the Oil Level, page 20. Slowly add additional oil to bring the level to the Full mark on the dipstick. 1. Disengage the PTO, set the parking brake, stop the engine, and remove the ignition key. 2. Clean around the air cleaner to prevent dirt from getting into the engine and causing damage.
Cleaning the Foam and Paper Elements Removing the Spark Plug Foam Element: 1. Disengage the PTO, set the parking brake, stop the engine, and remove the key. 1. Wash the foam element in liquid soap and warm water. When the element is clean, rinse it thoroughly. 2. Pull the wire off of the spark plug (Fig. 21). Clean around the spark plug to prevent dirt from falling into the engine and potentially causing damage. 2. Dry the element by squeezing it in a clean cloth. Do not oil the element.
Installing the Spark Plug 1. Install the spark plug. Make sure that the air gap is set correctly. 2 2. Tighten the spark plug to 30 ft.-lb. (41 N⋅m). 3. Push the wire onto the spark plug (Fig. 21). 1 3 m–151 Figure 23 Cutting Blades 1. Cutting edge 2. Curved area Maintain sharp blades throughout the cutting season because sharp blades cut 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.
2. Check the balance of the blade by putting it on a blade balancer (Fig. 28). If the blade stays in a horizontal position, the blade is balanced and can be used. If the blade is not balanced, file some metal off the end of the sail area only (Fig. 26). Repeat this procedure until the blade is balanced. Warning A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. • Always replace bent or damaged blade with a new blade.
Servicing the Battery Warning Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. Check the electrolyte level in the battery every 25 hours. Always keep the battery clean and fully charged. Use a paper towel to clean the battery case. If the battery terminals are corroded, clean them with a solution of four parts water and one part baking soda.
Checking the Electrolyte Level 4. Slide the rubber cover up the positive (red) cable. Disconnect the positive (red) cable from the battery post (Fig. 31). Danger 5. Remove the battery hold-down (Fig. 31) and lift the battery from the battery tray. 6 4 Battery electrolyte contains sulfuric acid which is a deadly poison and causes severe burns. 5 • Do not drink electrolyte and avoid contact with skin, eyes or clothing. Wear safety glasses to shield your eyes and rubber gloves to protect your hands.
Draining the Fuel Tank 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. 32) on the battery case. Danger 6. Reinstall the battery vent caps. In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. Charging the Battery Important Always keep the battery fully charged (1.260 specific gravity).
Replacing the Fuel Filter 2. Check the air pressure of all four tires. If needed, adjust to the recommended inflation; refer to Tire Pressure, page 28. Replace the fuel filter after every 100 operating hours or yearly, whichever occurs first. 3. Set the height-of-cut at 3 in. (76 mm). Never install a dirty filter if it is removed from the fuel line. 4. Carefully rotate the blade(s) from side to side (Fig. 36). Measure between the outside cutting edges and the flat surface (Fig. 36).
Adjusting the Front-to-Rear Blade Slope 2 F ront 1078 Check the front-to-rear blade level any time you install the mower. If the front of the mower is more than 5/16 in. (7.9 mm) lower than the rear of the mower, adjust the blade level using the following instructions: 1. Position the mower on a flat surface. Disengage the PTO, set the parking brake, stop the engine, and remove the key. Disconnect the spark plug wire(s) from the spark plug(s). 3 1 2. Check the air pressure of all four tires.
Inspecting the Belts Note: Check to ensure that the length of exposed thread on the spring eye bolt is 1/8 in. (3 mm) (Fig. 41). Inspect all belts every 100 hours. 7. Install the belt covers over the outside spindles. Check the belts for cracks, frayed edges, burn marks, or any other damage. Replace damaged belts. 1 5 Replacing the Mower Belt Squealing when the belt is rotating, blades slipping when cutting grass, frayed belt edges, burn marks, and cracks are signs of a worn mower belt.
Fuse 4. Remove the hairpin cotter and washer from the rear trunion rod (Fig. 44) on each side of the mower. The electrical system is protected by fuses. It requires no maintenance; however, if a fuse blows, check the component/circuit for a malfunction or short. 5. Remove the hairpin cotter and washer at the mower leveling brackets (Fig. 44) on each side of the mower. Note which hole the leveling bracket is mounted in for future installation. Slide the brackets off of the mounting pin.
Replacing the Grass Deflector 1 Warning An uncovered discharge opening could allow the lawn mower to throw objects in the operator’s or bystander’s direction and result in serious injury. Also, contact with the blade could occur. 3 2 Never operate the lawn mower unless you install a cover plate, a mulch plate, or a grass chute and catcher. 1. Remove the locknut, bolt, and spring holding the deflector to the mower brackets (Fig. 47). Remove the damaged or worn grass deflector. m–5173 Figure 46 1.
