Tips for Mowing Grass Long Grass Fast Throttle Setting 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. For best mowing and maximum air circulation, operate the engine at the Fast position.
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) m–6439 Figure 20 1. Oil dipstick 2. Filler tube Viscosity: See the table below. 3.
2. Remove the old filter and wipe the filter adapter gasket surface (Fig. 23). 3. Disengage the PTO and set the parking brake. 4. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3. Apply a thin coat of clean oil to the rubber gasket on the replacement filter (Fig. 23). 5. Slide the drain hose over the drain valve. 3 6. Place a pan below the drain hose. Rotate oil drain valve to allow oil to drain (Fig. 22). 2 7.
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.
Servicing the Cutting Blades 1 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. 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.
Checking for Bent Blades 1. Rotate the blades until the ends face forward and backward (Fig. 29). Measure from a level surface to the cutting edge, position A, of the blades (Fig. 29). Note this dimension. 2 m–6427 1 5 A 3 A 4 m–6430 Figure 30 1. Sail area of blade 2. Blade 3. Curved washer Sharpening the Blades 3 3 4. Blade bolt 5. Blade stiffener 1. Use a file to sharpen the cutting edge at both ends of the blade (Fig. 31). Maintain the original angle.
2. Install the blade stiffener, the curved washer (cupped side toward the blade) and the blade bolt (Fig. 30). Torque the blade bolt to 35–65 ft-lb (47–88 N⋅m). Greasing and Lubrication Lubricate the machine when shown on the Check Service Reference Aid decal (Fig. 33) located beneath the seat. Grease more frequently when operating conditions are extremely dusty or sandy. 1 Grease with No. 2 general purpose lithium base or molybdenum base grease. How to Grease m–6435 1.
6. Secure the battery with the hold-down (Fig. 35). 4. Disconnect the negative (black) ground cable from the battery post (Fig. 35). Checking the Electrolyte Level Warning Danger Incorrect battery cable routing could damage the tractor and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. Battery electrolyte contains sulfuric acid which is a deadly poison and causes severe burns.
Draining the Fuel Tank Important Do not overfill the battery because electrolyte (sulfuric acid) can cause severe corrosion and damage to the chassis. Danger 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. 36) on the battery case. 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. 6.
Replacing the Fuel Filter Leveling the Mower from Side-to-Side Replace the fuel filter after every 100 operating hours or yearly, whichever occurs first. The mower blades must be level from side to side. Check the side-to-side level any time you install the mower or when you see an uneven cut on your lawn. Never install a dirty filter if it is removed from the fuel line. 1. Park the machine on a level surface and disengage the blade control (PTO). 1.
Adjusting the Front-to-Rear Blade Slope 7. To level the blade(s), reposition the leveling bracket(s) in a different hole and install the washer and hairpin cotter. (Fig. 41 and 42). A front hole lowers the blade height and a rear hole raises its height. Adjust both sides as required. 1 Check the front-to-rear blade level any time you install the mower. If the front of the mower is more than 5/16 inch (7.9 mm) lower than the rear of the mower, adjust the blade level using the following instructions: 1.
8. Set the height-of-cut at position D [3 inch (76 mm)] and carefully rotate the blades so they are facing front to rear (Fig. 44). 9. Measure from the tip of the front blade to the flat surface and the tip of the rear blade to the flat surface (Fig. 44). If the front blade tip is not 1/16–5/16 inch (1.6–7.9 mm) lower than the rear blade tip, adjust the front locknuts. 1 1 2 2 m–6427 3 2 3 1 4 1 m–4634 Figure 45 2 1. Locknut and adjusting nut 2.
