hydraulic filters and oil can result in irreparable
damage to the transaxle drive system.
Bleeding the Hydraulic System
1. Raise the rear of machine up and support with jack
stands (or equivalent support) just high enough to
allow drive wheels to turn freely.

Jacking points
2. Enter the operator's position. Start engine and
move throttle control ahead to 1/2 throttle position.
Disengage parking brake.
A. Move the bypass levers into the pushing the
machine position; refer to the Pushing the
Machine by Hand section in Operation. With
the bypass valves open and the engine running,
slowly move the motion control levers in both
forward and reverse (5 or 6 times).
B. Move the bypass levers into the operating
the machine position. With the bypass valve
closed and the engine running, slowly move the
directional control in both forward and reverse
directions (5 to 6 times).
C. Stop the engine and check the oil level in the
expansion reservoir. Add the specified oil as
until it reaches the FULL COLD line on the
expansion reservoir.
3. Repeat step 2 until all the air is completely purged
from the system.
When the transaxle operates at normal noise levels
and moves smoothly forward and reverse at normal
speeds, then the transaxle is considered purged.
4. Check the oil level in the expansion reservoir one
last time. Add the specified oil as until it reaches
the FULL COLD line on the expansion reservoir
if necessary.

Maintenance
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.
WARNING
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. Inspect the cutting edges (Figure 53). If the edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to Sharpening the Blades.
2. Inspect the blades, especially the curved area
(Figure 53). If you notice any damage, wear, or a slot
forming in this area (Figure 53), immediately install a
new blade.
