Loading a unit onto a trailer or truck increases the possibility of backward tip–over and could cause serious injury or death. • Use extreme caution when operating a unit on a ramp.
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 fast.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Each Use Maintenance Procedure • • • • • Check the engine oil level. Check the safety system. Clean the cooling system.1 Clean the mower housing. Check the air cleaner. Every 5 Hours • Check the cutting blades. Every 25 Hours • • • • • Every 100 Hours • Change the engine oil.1 • Inspect the paper element of the heavy duty air cleaner.
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.
Sharpening the Blades dimension exceeds 1/8 inch (3 mm), the blade is bent and must be replaced. Refer to Removing the Blades, and Installing the Blades on page 28. Warning Warning When sharpening blade, pieces of blade could be thrown and cause serious injury. A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. Wear proper eye protection when sharpening blade. • Always replace bent or damaged blade with a new blade.
Engine Oil 4. Slide the oil dipstick fully into the filler tube, but do not thread it onto the tube. Pull the dipstick out and look at the metal end (Fig. 34). If the oil level is low, slowly pour only enough oil into the filler tube to raise the level to, but not over, the “F” mark on the dipstick. Change the oil after every 100 operating hours. Oil Type: Detergent oil (API service SG, SH, SJ, or higher) Crankcase Capacity: w/filter, 2.1 qt. (2 l) 2 Viscosity: See the table below.
Air Cleaner Note: Dispose of the used oil at a certified recycling center. Primary Filter: Check and/or replace after every 200 operating hours or more often in dusty conditions. 5. Clean around the oil reservoir and unscrew the cap (Fig. 35). Safety Filter: Replace after every 600 operating hours. 6. Slowly pour approximately 80% of the specified amount of oil, page 29, into the filler tube (Fig. 33). Check the oil level; refer to Checking the Oil Level, page 29.
Servicing the Primary Filter Removing the Spark Plug(s) Check and/or replace it after 200 operating hours. 1. Disengage the PTO, set the parking brake, stop the engine, and remove the key. If the primary filter is dirty, bent, or damaged then replace the filter. 2. Pull the wire(s) off the spark plug(s) (Fig. 38). Clean around the spark plug(s) to prevent dirt from falling into the engine and potentially causing damage. Do not clean the primary filter. 3. Remove the spark plug(s) and metal washer.
5. Open the fuel shut-off valve. Allow gasoline to drain into a gas can or drain pan. 2. Check the gap between the center and side electrodes (Fig. 39). Bend the side electrode (Fig. 39) if the gap is not correct. 3 Installing the Spark Plug(s) 2 2 1. Install the spark plug(s). Make sure that the air gap is set correctly. 2. Tighten the spark plug(s) to 30 ft.-lb. (41 N⋅m). 3. Push the wire(s) onto the spark plug(s) (Fig. 38).
Greasing and Lubrication 2. Remove the hex plug. Thread a grease zerk into hole. 3. Pump grease into zerk until it oozes out around top bearing. Lubricate the machine when shown on the Check Service Reference Aid decal (Fig. 41). Grease more frequently when operating conditions are extremely dusty or sandy. 4. Remove grease zerk in hole. Reinstall hex plug and cap. Grease with No. 2 general purpose lithium base or molybdenum base grease.
1 Checking the Tire Pressure 4 Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut. Check the pressure at the valve stem after every 50 operating hours or monthly, whichever occurs first (Fig. 43). Check the tires when they are cold to get the most accurate pressure reading. 3 2 Pressure: 13 psi (90 kPa) drive wheels and caster wheels. m–4638 Figure 44 1 1. Slotted nut 2. Two threads or less showing 3. Hole in threaded rod 4.
Servicing the Hydraulic System 1 2 Check the hydraulic fluid level before engine is first started. Check the hydraulic fluid level after first 8 operating hours. 4 3 Check the hydraulic fluid level after every 25 operating hours.
