1. Install the empty grass bag on the machine.

2. Start the engine.

3. Engage the blade.

   Note: The bag should begin to inflate, indicating that the blade is engaged and rotating.

4. Release the blade-control bar.

   Note: If the bag does not immediately deflate, the blade is still rotating. The blade-brake clutch may be deteriorating and, if ignored, could result in an unsafe operating condition. Have the machine inspected and serviced by an Authorized Service Dealer.

5. Stop the engine and wait for all moving parts to stop.

1. Move the machine onto a paved surface in a non-windy area.

2. Set all 4 wheels to the 76 mm (3 inch) cutting-height setting; refer to Adjusting the Cutting Height.

3. Take a half sheet of newspaper and crumple it into a ball small enough to go under the machine housing (about 76 mm or 3 inches in diameter).

4. Place the newspaper ball about 13 cm (5 inches) in front of the machine (Figure 20).

   

   Figure 20

3. Remove the bag rod on the grass bag from the notches at the base of the handle (Figure 22).

4. Install the discharge plug; refer to Recycling the Clippings.

5. Lower the rear door.

• Review the safety instructions and read this manual carefully before operating the machine.

• Clear the area of sticks, stones, wire, branches, and other debris that the blade could hit and throw.

• Keep everyone, especially children and pets, away from the area of operation.

• Avoid striking trees, walls, curbs, or other solid objects. Never deliberately mow over any object.

• If the machine strikes an object or starts to vibrate, immediately stop the engine, disconnect the wire from the spark plug, and examine the machine for damage.

• Maintain a sharp blade throughout the cutting season. Periodically file down nicks on the blade.

• Replace the blade when necessary with an original Toro replacement blade.

• Mow only dry grass or leaves. Wet grass and leaves tend to clump on the yard and can cause the machine to plug or the engine to stall.

  Warning

  Wet grass or leaves can cause serious injury if you slip and contact the blade.

  Mow only in dry conditions.

• Clean under the machine after each mowing; refer to Cleaning under the Machine.

• Keep the engine in good running condition.

• Clean the air filter frequently. Mulching stirs up more clippings and dust which clogs the air filter and reduces engine performance.

• Set the engine speed to the fastest position for the best cutting results.

  Warning

  Operating a machine with its engine running at a speed greater than the factory setting can cause the machine to throw a part of the blade or engine at you or bystanders, resulting in serious personal injury or death.

  • Do not change the engine speed setting.

  • If you suspect the engine speed is faster than normal, contact an Authorized Service Dealer.

• Grass grows at different rates at different times of the year. In the summer heat, it is best to cut grass at the 64 mm (2-1/2 inch), 76 mm (3 inch), or 89 mm (3-1/2 inch) cutting-height settings. Cut only about a third of the grass blade at a time. Do not cut below the 64 mm (2-1/2 inch) setting unless the grass is sparse or it is late fall when grass growth begins to slow down.

• When cutting grass over 15 cm (6 inches) tall, first mow at the highest cutting height setting and walk slower; then mow again at a lower setting for the best lawn appearance. If the grass is too long and the leaves clump on top of the lawn, the machine may plug and cause the engine to stall.

• Alternate the mowing direction. This helps disperse the clippings over the lawn for even fertilization.

If the finished lawn appearance is unsatisfactory, try 1 or more of the following:

• Sharpen the blade.

• Walk at a slower pace while mowing.

• Raise the cutting height on your machine.

• Cut the grass more frequently.

• Overlap cutting swaths instead of cutting a full swath with each pass.

• After cutting the lawn, ensure that half of the lawn shows through the cut leaf cover. You may need to make more than a single pass over the leaves.

• For light leaf coverage, set all the wheels at the same cutting height setting.

• Slow down your mowing speed if the machine does not cut the leaves finely enough.

Important: Do not operate the engine without the air filter assembly in place; otherwise, extreme engine damage will occur.

1. Stop the engine and wait for all moving parts to stop.

2. Disconnect the wire from the spark plug.

3. Remove the 2 nuts that secure the cover (Figure 23).

4. Remove the cover.

   Note: Be careful to prevent dirt and debris from falling into the base of the air cleaner.

5. Remove the foam and paper elements from the base of the air cleaner (Figure 23).

   5. Base

7. Inspect the foam and paper elements, and replace them if they are damaged or excessively dirty.

8. If the paper element is excessively dirty, replace it.

   Note: Never try to brush dirt off the paper element; brushing forces the dirt into the fibers.

9. Clean the foam element in warm, soapy water or in a nonflammable solvent.

   Note: Do not use gasoline to clean the foam element because it could create a risk of fire or explosion.

10. Rinse and dry the foam element thoroughly.

11. Dip the foam element in clean engine oil, then squeeze out the excess oil.

    Note: Excess oil in the foam element restricts the air flow through the element and may reach the paper filter and clog it.

12. Wipe dirt from both the base and the cover of the air cleaner with a moist rag.

    Note: Be careful to prevent dirt and debris from entering the air duct leading to the carburetor.

13. Install the air cleaner elements and ensure that they are properly in place.

14. Securely install the cover with the 2 nuts that you removed in step 3.

1. Run the engine to warm the engine oil.

   Note: Warm oil flows better and carries more contaminants.

   Warning

   Oil may be hot after engine has been run, and contact with hot oil can cause severe personal injury.

   Avoid contacting the hot engine oil when you drain it.

2. Stop the engine and wait for all moving parts to stop.

3. Disconnect the wire from the spark plug.

4. Close the fuel valve by moving the fuel-valve lever to the left (Figure 15).

5. Drain the gasoline from the fuel tank.

6. Place a suitable drain pan under the dipstick/oil drain.

7. Clean around the dipstick.

   3. Air gap (not to scale)

6. Carefully install the spark plug by hand (to avoid cross threading) until it is hand tight.

7. Tighten the spark plug to 23 N-m (2.3 kgf-m, 17 ft-lb).

   Important: A loose spark plug can become very hot and can damage the engine; overtightening a spark plug may damage the threads in the cylinder head.

8. Connect the wire to the spark plug.

If the machine is new, does not self-propel, or it tends to creep forward, adjust the drive cable.

1. Move the machine outside and onto a paved surface near a solid wall to safely prevent the machine from moving forward while the engine is running.

2. Position the machine with the front tires against the wall.

   Note: Ensure that the area is well ventilated and clear of debris that could be thrown by the machine.

3. Shift the transmission to third gear.

4. Start the engine; refer to Starting the Engine.

5. Pull the self-propel-drive bar to the handle.

   Note: The wheels should start to turn as the self-propel-drive bar just touches the handle.

6. Shut off the engine.

7. If you must adjust the machine, do the following:

   • If the wheels do not spin when you engage the self-propel-drive bar, the traction belt is too loose. Rotate the wheel-drive-control knob (Figure 25) clockwise 1 turn and repeat steps 4 through 6.

     

     Figure 25

     1. Wheel-drive-control knob

   • If the wheels spin before you fully engage the self-propel-drive bar, the traction belt is too tight. Rotate the wheel-drive-control knob (Figure 25) counterclockwise 1 turn and repeat steps 4 through 6.

8. For a new traction belt, rotate the drive cable adjustment knob clockwise 1 additional turn to allow for the normal stretching of the belt during the break-in period.

   Note: You can skip this step if you are adjusting a used belt.

Always mow with a sharp blade. A sharp blade cuts cleanly and without tearing or shredding the grass blades.

1. Stop the engine and wait for all moving parts to stop.

2. Disconnect the wire from the spark plug.

3. Close the fuel valve by moving the fuel-valve lever to the left (Figure 15).

Inspecting the Blade

Maintenance Service Interval	Maintenance Procedure
Before each use or daily	Inspect the mower blades for wear or damage.

Carefully examine the blade for sharpness and wear, especially where the flat and the curved parts meet (Figure 27A). Because sand and abrasive material can wear away the metal that connects the flat and curved parts of the blade, check the blade before using the machine. If you notice a slot or wear (Figure 27B and Figure 27C), replace the blade; refer to Removing the Blade.

2. Flat part of the blade
3. Wear
4. Slot formed

Note: For the best performance, install a new blade before the mowing season begins. During the year, file down any small nicks to maintain the cutting edge.

Danger

A worn or damaged blade can break, and a piece of the blade could be thrown in your direction or in the direction of bystanders, resulting in serious personal injury or death.

• Inspect the blade periodically for wear or damage.

• Replace a worn or damaged blade.

Inspecting the Accelerator

Maintenance Service Interval	Maintenance Procedure
Before each use or daily	Inspect the accelerator for wear or damage.

Carefully examine the accelerator for excessive wear (Figure 28). Because sand and abrasive material can wear away the metal (especially in the area shown as item 2 in Figure 28), check the accelerator before using the machine. If you notice that a tab on the accelerator has been worn down to a sharp edge or there is a crack, replace the accelerator; refer to Removing the Blade.

Warning

A worn or damaged accelerator can break, and a piece of the accelerator could be thrown at you or bystanders, resulting in serious personal injury or death.

• Inspect the accelerator periodically for wear or damage.

• Replace a worn or damaged accelerator.

Sharpening the Blade

Maintenance Service Interval	Maintenance Procedure
Every 50 hours	Sharpen or replace the blade.Maintain it more frequently if the edge dulls quickly in rough or in sandy conditions.

File the top side of the blade to maintain its original cutting angle (Figure 29A) and inner cutting edge radius (Figure 29B). The blade will remain balanced if you remove the same amount of material from both cutting edges.

Figure 29

1. Sharpen the blade at this angle only.
2. Maintain the original radius here.

The blade-brake cable is adjusted at the factory; you do not need to adjust it unless you are replacing the cable or the blade-brake belt. If you need to replace the cable, replace both the cable and the belt at the same time.

1. Install a new blade-brake belt and assemble the machine except for the 2 belt covers on the top of the mower housing.

2. Install the new blade-brake cable, but do not tighten the cable clamp on the top of the mower housing (Figure 31).

   

   Figure 31

   1. Spring
   2. Cable clamp and screw

3. Insert a 8 mm (5/16-inch) thick spacer between the blade-brake-control lever and the control bracket on the handle (Figure 32).

   2. Self-propel-drive bar
   3. Control bracket
   4. Spacer—8 mm (5/16 inch) thick
   5. Blade-brake-control lever

   Important: Replacing the cable without replacing the belt may cause the gap between the blade-brake-control lever and the control bracket to be incorrect. If the gap is less than 8 mm (5/16 inch), the blade brake will not function properly and the blade will not stop within 3 seconds. If the gap is greater than 8 mm (5/16 inch), the belt will not properly drive the blade.

4. Pull the cable tight to remove the slack (but do not stretch the cable spring) and tighten the cable clamp screw to lock the adjustment in place.

5. Remove the spacer.

6. Ensure that there is slack in the cable and a gap between the blade-brake-control lever and the control bracket when the self-propel-drive bar is not engaged.

7. Install the 2 belt covers on the top of the mower housing.

   Important: After installing the new blade-brake belt and blade-brake cable, check that the blade-brake clutch is operating properly and that the blade stops within 3 seconds; refer to Checking the Blade-Brake Clutch.
