Mower Deck Maintenance; Servicing The Cutting Blades - Toro GrandStand 74558 Operator's Manual

Check hydraulic lines and hoses for leaks, loose fittings,
kinked lines, loose mounting supports, wear, weather
and chemical deterioration. Make necessary repairs
before operating.
Note: Keep areas around hydraulic system clean from
grass and debris build up.
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• If hydraulic fluid is injected into the skin
it must be surgically removed within a few
hours by a doctor familiar with this type of
injury. Gangrene may result if this is not
done.
• Keep body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks.
• Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
• Make sure all hydraulic fluid hoses and
lines are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to hydraulic system.

Servicing the Cutting Blades

To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement, you
may want to keep extra blades on hand.
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 blades 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 blades
and set the parking brake. Turn the ignition key to off.
Remove the key and disconnect the spark plug wires
from the spark plugs.
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges (Figure 71). 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. If you
notice any cracks, wear, or a slot forming in this area
