Tips for Mowing Grass 1 Fast Throttle Setting 2 For best mowing and maximum air circulation, operate the engine at the Fast position. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower. Cutting a Lawn for the First Time m–6479 Figure 17 1.
Long Grass If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. When Stopping If the machine’s forward motion must be stopped while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Each use After first 5 hours Maintenance Procedure • Check the engine oil level. • Check the safety system. • Clean the mower housing. • Change the engine oil. 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 1 2 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: 3 • 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 (Models 74330 and 74350 only) m–6439 Figure 18 1. Oil dipstick 2. Filler tube Viscosity: See the table below. 3.

Important worn. 2 1 Replace the foam element if it is torn or Cleaning the Paper Element: 1. Lightly tap the element on a flat surface to remove dust and dirt. 2. Carefully clean the rubber seal on the paper element to prevent debris from entering the engine. 3. Inspect the element for tears, an oily film, and damage to the rubber seal. Important Never clean the paper element with pressurized air or liquids, such as solvent, gas, or kerosene.
1 Servicing the Cutting 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. 2 Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade.
Warning 2 A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. 1 3 • Always replace bent or damaged blade with a new blade. • Never file or create sharp notches in the edges or surfaces of blade. m–151 Figure 26 1. Cutting edge 2. Curved area 3. Wear/slot forming Removing the Blades Checking for Bent Blades The blades must be replaced if a solid object is hit, if the blade is out of balance, or the blade is bent.
3. Clean the grease fittings with a rag. Make sure to scrape any paint off of the front of the fitting(s). 1 4. Connect a grease gun to the fitting. Pump grease into the fittings until grease begins to ooze out of the bearings. m–1854 Figure 29 5. Wipe up any excess grease. 1. Sharpen at original angle Where to Add Grease 2. Check the balance of the blade by putting it on a blade balancer (Fig. 30). If the blade stays in a horizontal position, the blade is balanced and can be used.
Servicing the Battery Warning Warning Incorrect battery cable routing could damage the tractor and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. CALIFORNIA Proposition 65 Warning • Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable. • Always connect the positive (red) battery cable before connecting the negative (black) cable.
3. Remove the vent caps from the battery (Fig. 34). 5. Slide the red terminal boot onto the positive (red) battery post. 4. Slowly pour distilled water into each battery cell until the electrolyte level is up to the Upper line (Fig. 34) on the battery case. 6. Secure the battery with the hold-down (Fig. 33). Checking the Electrolyte Level Important Do not overfill the battery because electrolyte (sulfuric acid) can cause severe corrosion and damage to the chassis. Danger 5.
Draining the Fuel Tank Replacing the Fuel Filter Replace the fuel filter after every 100 operating hours or yearly, whichever occurs first. Danger Never install a dirty filter if it is removed from the fuel line. 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. 1. Park the machine on a level surface and disengage the blade control (PTO). 2.
2. Move the motion control levers to the brake position, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 1 3.
