Leveling the Mower Deck

Setting Up the Machine
Note: Ensure that the mower deck is leveled before
matching the height of cut (HOC).
1. Position the machine on a flat surface.
2. Move the speed control lever to the neutral position
to stop the machine.
3. Disengage the PTO, engage the parking brake, stop the
engine, and wait for all moving parts to stop.
4. Check the tire pressure of the drive tires. If needed,
adjust the pressure to 103 kPa (15 psi)
Deck Leveling
1. Stop the machine and move the speed control lever to
the neutral position.
2. Disengage the PTO, engage the parking brake, stop the
engine, and wait for all moving parts to stop.
3. Verify all hairpin cotter pins are in the 7.62 cm (3 inch)
mower deck height holes with the spacers under the
hairpin cotter pins (Figure 63).

4. Shorten or lengthen each mower deck support pin to
obtain blade tip height of 7.62 cm (3 inches) at the
front of the deck and 8.26 cm (3 1/4 inches) at the rear
of the deck (Figure 63).
Note: The front pins are thread into the mower deck
and have a jam nut. The rear pins have a rod end
threaded into them with a jam nut.

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.
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. For
convenient sharpening and replacement, you may want to
keep extra blades on hand.
DANGER
A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator's
or bystander's area, resulting in serious personal
injury or death.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade.
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the blade
control switch (PTO), and set the parking brake. Turn the
ignition key to Off. Remove the key.
Inspecting the Blades
Service Interval: Before each use or daily
1. Lift the mower deck and secure in the raised position.
Refer to Raising the Mower Deck into Service Position
(page 20).
2. Inspect the cutting edges (Figure 64). If the edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to Sharpening the Blades.
3. Inspect the blades, especially the curved area (Figure
64). If you notice any damage, wear, or a slot forming
in this area (Figure 64), immediately install a new blade.
