While sitting on the seat, engage the parking brake, engage the PTO, and try to start the engine; the engine should not crank. 1 4 2.
Adjusting the Anti-scalp Rollers Caution Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended. Whenever you change the height-of-cut, adjust the height of the anti-scalp rollers. Always remove the ignition key and set the parking brake when leaving the machine unattended, even for a few minutes. Adjusting the Outer Roller 1. Disengage the PTO, move the motion control levers to the neutral locked position, and set the parking brake.
Adjusting the Center Rollers Positioning the Seat 1. Disengage the PTO, move the motion control levers to the neutral locked position, and set the parking brake. The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable. 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 1. To adjust, move the lever sideways to unlock the seat (Fig. 20). 3.
Changing to Machine Operation Warning Turn the bypass valves in to operate (Fig. 21). Driving on a street or roadway without turn signals, lights, reflective markings, or a slow moving vehicle emblem is dangerous and can lead to accidents that cause personal injury. Note: Do not overtighten the bypass valves. Note: The machine will not drive unless the bypass valves are turned in. Do not drive the machine on a public street or roadway.
Mowing Direction Important Do not attempt to turn the machine while on the ramp; you may lose control and drive off the side. Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings, which enhances decomposition and fertilization. Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp. Both maneuvers can cause the machine to tip backward. Mow at Correct Intervals Warning Normally, mow every 4 days.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval After First 8 Hours Each Use Maintenance Procedure • Check the hydraulic fluid level. • Change the engine oil. • Change the hydraulic filter. • • • • Check the engine oil level. Check the safety system. Clean the engine air intake1. Clean the mower housing. Every 5 Hours • Check the cutting blades.
Important Refer to your engine operator’s manual for additional maintenance procedures. Caution If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition and disconnect the wire from the spark plug(s) before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug.
Checking for Bent Blades Removing the Blades 1. Rotate the blades until the ends face forward and backward (Fig. 24). Measure from a level surface to the cutting edge of the blades (Fig. 25). Note this dimension. Replace any blade if it hits a solid object, is out of balance, or is bent. To ensure optimum performance and continued safety conformance of the machine, use genuine Toro replacement blades.
3. Remove the air intake screen, recoil starter, and fan housing (Fig. 29). 1. Use a file to sharpen the cutting edge at both ends of the blade at the original angle (Fig. 27). 5 3 1 2 m–1854 Figure 27 4 1. Sharpen at original angle Note: The blade retains its balance if the same amount of material is removed from both cutting edges. 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.
3. Replace the paper element if it is damaged, or cannot be cleaned thoroughly. 3. Clean around the air cleaner to prevent dirt from getting into the engine and causing damage (Fig. 30). 6 2 Installing the Foam and Paper Elements 3 Important To prevent engine damage, always operate the engine with the complete foam and paper air cleaner assembly installed. 4 1. Carefully slide the foam element onto the paper air cleaner element (Fig. 30). 5 2.
7. Rotate oil drain valve to allow oil to drain (Fig. 32). 4. Clean around the oil dipstick (Fig. 31) so that dirt cannot fall into the filler hole and damage the engine. 2 1 1 Figure 32 m–7449 1. Oil drain valve Figure 31 1. Oil dipstick 2 2. Drain hose 2. Filler tube 8. When oil has drained completely, close the drain valve. 9. Remove the drain hose (Fig. 32). 5. Unscrew the oil dipstick and wipe the end clean (Fig. 31). Note: Dispose of the used oil at a recycling center. 6.
Checking the Spark Plug(s) 3. Apply a thin coat of new oil to the rubber gasket on the replacement filter (Fig. 33). 1. Look at the center of the spark plug(s) (Fig. 35). If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means that the air cleaner is dirty. 4.
4. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 5. Disconnect the fuel line from the fuel filter (Fig. 36). 6. Open the fuel shutoff valve (Fig. 36). Note: Allow gasoline to drain into a fuel container can or drain pan (Fig. 36). 5. Close the fuel shutoff valve (Fig. 36). Note: Now is the best time to install a new fuel filter because the fuel tank is empty. 7. Install the fuel line onto the fuel filter.
5. Wipe up any excess grease. 4. Grease the idler pulley pivot (Fig. 38). 5. Grease the fittings on the push arms (Fig. 38). Where to Add Grease Lubricate the grease fittings as shown on the Check Service Reference Aid decal (Fig. 37). Where to Add Light Oil or Spray Lubrication Greasing the Front Caster Pivots Lubricate the machine in the following areas with spray type lubricant or light oil. Lubricate every 160 hours. Lubricate the front caster pivots once a year. • Seat switch actuator 1.
Note: There are 2 ways of checking the hydraulic oil. One is for warm oil and the other for cold oil. The baffle inside the tank has 2 levels depending on whether the oil is warm or cold. Warning Hydraulic fluid escaping under pressure can penetrate skin and cause injury. 1. Move the machine onto a level surface and set the parking brake.
5. Check hydraulic fluid level and add fluid as required to maintain the proper level. 4. Apply a thin coat hydro fluid to the rubber gasket on the replacement filter (Fig. 42). 6. Repeat this procedure on the opposite wheel. 1 Warning 3 Hydraulic fluid escaping under pressure can penetrate skin and cause injury. 2 • If hydraulic fluid is injected into the skin it must be surgically removed within a few hours by a doctor familiar with this type of injury; otherwise, gangrene may result.
3. Tilt the seat forward. 4. Begin with either the left or right motion control lever. 7. Check where the control lever is relative to the notch in the console (Fig. 43). It should be centered, allowing the lever to pivot outward to the neutral lock position. 5. Move lever to the neutral position but not locked (Fig. 43). 8. If adjustment is needed, loosen the nut and jam nut against the yoke (Fig. 44). 9.
Setting the Left-hand Hydraulic Pump Neutral Position 3. Adjust the pump rod length by rotating the double nuts on the rod in the appropriate direction until the wheel is still or slightly creeps in reverse (Fig. 44). 1. Start the engine, open the throttle halfway and release the parking brake. Refer to Starting and Stopping the Engine on page 18. 4. Move the motion control lever forward and reverse, then back to neutral. The wheel must stop turning or slightly creep in reverse.
