Recycling the Clippings
This machine comes from the factory ready to recycle grass and leaf clippings back into the lawn. To prepare the machine to recycle:
-
If the grass bag is on the machine, remove it (A of Figure 15).
-
If the rear-discharge plug is not installed, grip it by the handle, raise the rear deflector, and insert it into the rear-discharge chute until the latch locks into place (B of Figure 15).
Warning
Operating the machine to recycle lawn clippings without the plug in place allows objects to be thrown toward you or bystanders. Also, contact with the blades could occur. Thrown objects or blade contact can cause serious injury or death.
Ensure that the rear-discharge plug is in place before you recycle the clippings. Never engage the blades without either the rear-discharge plug or the grass bag installed on the machine.
Bagging the Clippings
Use the grass bag when you want to collect grass and leaf clippings from the lawn.
Warning
A worn grass bag could allow small stones and other similar debris to be thrown toward you or bystanders, resulting in serious personal injury or death.
Check the grass bag frequently. If it is damaged, install a new Toro replacement bag.
Warning
The blades are sharp; contacting the blades can result in serious personal injury.
Shut off the engine and wait for all moving parts to stop before leaving the operating position.
Installing the Grass Bag
-
Shut off the engine and wait for all moving parts to stop.
-
Raise and hold up the rear deflector (A of Figure 16).
-
Remove the rear-discharge plug by pushing in the latch with your thumb and pulling the plug out from the machine (B and C of Figure 16).
-
Install the bag-rod ends into the notches at the base of the handle, and rock the bag back and forth to ensure that the bag-rod ends are seated at the bottom of both notches (D of Figure 16).
-
Lower the rear deflector until it rests on the grass bag.
Removing the Grass Bag
Danger
The machine can throw grass clippings and other objects through an opening in the machine housing. Objects thrown with enough force could cause serious personal injury or death to you or to bystanders.

Operating Tips
General Tips
-
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 shut off 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 toward 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.
-
Cutting Grass
-
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.
Cutting Leaves
-
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.
After Operation
After Operation Safety
General Safety
-
Clean grass and debris from the machine to help prevent fires. Clean up oil or fuel spills.
