Operating Tips
General Mowing Tips
-
Inspect the area where you will use the machine and remove all objects that the machine could throw.
-
Avoid striking solid objects with the blades. Never deliberately mow over any object.
-
If the machine strikes an object or starts to vibrate, immediately shut off the engine, remove the key (if equipped), disconnect the wire from the spark plug, and examine the machine for damage.
-
For best performance, install new blades before the cutting season begins.
-
Replace the blades when necessary with Toro replacement blades.
Cutting Grass
-
Cut only about a third of the grass blade at a time. Do not cut below 51 mm (2 inches) 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, 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, the machine may plug and cause the engine to stall.
-
Wet grass and leaves tend to clump on the yard and can cause the machine to plug or the engine to stall. Avoid mowing in wet conditions.
-
Be aware of a potential fire hazard in very dry conditions, follow all local fire warnings, and keep the machine free of dry grass and leaf debris.
-
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:
-
Replace the blades or have them sharpened.
-
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.
-
If there are more than 13 cm (5 inches) of leaves on the lawn, mow at a higher cutting height and then again at the desired cutting height.
-
Slow down your mowing speed if the machine does not cut the leaves finely enough.

Inspecting the Blades
| Maintenance Service Interval | Maintenance Procedure |
|---|---|
| Before each use or daily |
|
-
Inspect the cutting edges (Figure 38). If the edges are not sharp or have nicks, remove the blades and have them sharpened or replace them.
-
Inspect the blades themselves, especially the curved area (Figure 38). If you notice any damage, wear, or a slot forming in this area, immediately replace it with a new blade.
Warning
If you allow a blade to wear, a slot will form between the sail and flat part of the blade. Eventually a piece of the blade may break off and be thrown from under the housing, possibly resulting in serious injury to you or bystanders.
-
Inspect the blade periodically for wear or damage.
-
Never try to straighten a blade that is bent or weld a broken or cracked blade.
-
Replace a worn or damaged blade.
-
-
Check for bent blades; refer to Checking for Bent Blades.
Checking for Bent Blades
-
Rotate the blades to the position shown in Figure 39.
-
Measure from a level surface to the cutting edges at locations A and B (Figure 39), and record both dimensions.
-
Rotate the blades so that their opposite ends are at locations A and B (Figure 39).
-
Repeat the measurements in step 2 and record them.
Note: If the difference between the dimensions A and B obtained in steps 2 and 4 exceeds 3 mm (1/8 inch), the blade is bent and you will need to replace it. Refer toRemoving the Blades and Installing the Blades.
Warning
A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders.
-
Always replace a bent or damaged blade with a new blade.
-
Never file or create sharp notches in the edges or surfaces of a blade.
Removing the Blades
Replace the blades when the machine hits a solid object or when a blade is out of balance or bent. Use only genuine Toro replacement blades.
Installing the Blades
-
Install the first blade so that it is horizontal, along with all mounting hardware as shown in Figure 41.
Note: Tighten the bolt with your fingers.
Important: Position the curved ends of the blades to point toward the machine housing. Be sure to nest the raised areas on each blade driver with the recesses in the head of its corresponding spindle, and the pins on the other side of each blade driver with the holes in its corresponding blade.
-
Steady each blade with a board and turn the blade bolt clockwise with a torque wrench as shown in Figure 42; torque the blade bolt to 82 N∙m (60 ft-lb).
-
Rotate the installed blade 1/4 turn until it is vertical, and install the other blade in the same manner as the first (refer to step 1).
Note: The blades should be perpendicular, forming an inverted “T” as shown in Figure 43.
-
Tighten the second blade; refer to step 2.
-
Rotate the blades by hand a full 360° turn to ensure that they do not touch.
Note: If the blades touch each other, they are not mounted correctly. Repeat steps 1 through 3, until the blades no longer touch each other.
Warning
Incorrectly installing the blades could damage the machine or cause an injury to you or bystanders.
Use care when installing the blades.
Storage
Store the machine in a cool, clean, dry place.
Storage Safety
Always shut off the machine, remove the ignition key (if equipped), wait for all moving parts to stop, and allow the machine to cool before adjusting, servicing, cleaning, or storing it.
