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 air intake screen. Clean the mower housing. Every 5 hours • Check the cutting blades. Every 25 hours • • • • • • Every 50 hours • Service the paper air cleaner.
Servicing the Engine Oil Changing and Draining the Oil Change the oil after the first 8 operating hours and every 100 operating hours thereafter. 1. Start the engine and let it run for five minutes. This warms the oil so that it drains better. Oil Type: Detergent oil (API service SC, SD, SE, SF, SG, or SH) 2. Park the machine so that the drain side is slightly lower than the opposite side to ensure that the oil drains completely.
Changing the Oil Filter Cleaning the Cooling System Replace the oil filter every 200 hours or every other oil change. Clean the air intake screen from grass and debris before each use. Note: Change the oil filter more frequently when operating conditions are extremely dusty or sandy. Clean the cooling fins and engine shrouds every 300 hours or yearly, whichever comes first. 1. Drain the oil from the engine; refer to Changing and Draining the Oil, page 20. 1.
Servicing the Air Cleaner Cleaning the Foam and Paper Elements Foam Element: Clean and oil after every 25 operating hours. 1. Foam Element A. Wash the foam element in liquid soap and warm water. When the element is clean, rinse it thoroughly. Paper Element: Clean after every 100 operating hours. Replace after every 200 operating hours or yearly, whichever comes first. B. Dry the element by squeezing it in a clean cloth (do not wring). Allow the element to air dry.
Installing the Foam and Paper Elements Checking the Spark Plug Important To prevent engine damage, always operate the engine with the complete foam and paper air cleaner assembly installed. 1. Look at the center of the spark plug(s) (Fig. 23). If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty. 1. Carefully slide the foam element into the paper air cleaner element (Fig. 19).
Servicing the Battery 4. Slide the rubber cover up the positive (red) cable. Disconnect the positive (red) cable from the battery post (Fig. 24). Warning 5. Remove the battery hold-down (Fig. 24) and lift the battery from the battery tray. 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. 6 4 5 7 2 Check the electrolyte level in the battery every 25 hours.
Checking the Electrolyte Level 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. 25) on the battery case. Danger 6. Reinstall the battery vent caps. Battery electrolyte contains sulfuric acid which is a deadly poison and causes severe burns. Charging the Battery • Do not drink electrolyte and avoid contact with skin, eyes or clothing.
Servicing the Fuse 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. 2 Fuse: Main F1—30 amp, blade-type Charge Circuit F2—25 amp, blade-type Optional Headlight Kit—10 amp, blade type 1. Raise the seat to gain access to the fuse holder (Fig. 27). 3 2. To replace a fuse, pull out on the fuse to remove it (Fig. 27). 1 m–4294 Figure 28 1. Fuel filter 2. Hose clamp 1 3.
Greasing and Lubrication Lubricate the machine when shown on the Check Service Reference Aid decal (Fig. 29) located beneath the seat. Grease more frequently when operating conditions are extremely dusty or sandy. Grease with No. 2 general purpose lithium base or molybdenum base grease. How to Grease 1. Disengage the PTO, stop the engine, and remove the key. 2. Clean the grease fittings with a rag. Make sure to scrape any paint off of the front of the fitting(s). m–5157 Figure 30 3.
Servicing the Cutting Blades Checking for Bent Blades 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. 1. Stop the engine, set the parking brake, remove the key, and disconnect the spark plug wire(s) from the spark plug(s). 2. Rotate the blades until the ends face forward and backward (Fig. 33).
Removing the Blades 2. Check the balance of the blade by putting it on a blade balancer (Fig. 37). 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. 35). Repeat this procedure until the blade is balanced. The blades must be replaced if a solid object is hit, if the blade is out of balance, or the blade is bent.
Front Adjusting the Front-to-Rear Blade Slope 2 2 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). 1 2. Check the air pressure of all four tires.
9. After adjusting both trunnion rod yokes evenly, secure the yokes with the hairpin cotters. Check the front-to-rear level again. Continue adjusting the yokes until the front blade tip is 1/16–5/16 in. (1.6–7.9 mm) lower than the rear blade tip (Fig. 41). 6. Measure between the tip of the front blade (Fig. 41) and the tip of the rear blade to the flat surface. If the front blade tip is not 1/16–5/16 in. (1.6–7.9 mm) lower than the rear blade tip, adjust the front trunnion rods. Front 2 1078 10.
