wear away the metal that connects the flat and curved

parts of the blade, check the blade before using the

machine. If you notice wear

DANGER

If the blade is allowed to wear, a slot will form

between the sail and flat part of the blade

(Figure

66). Eventually a piece of the blade

may break off and be thrown from under the

housing, possibly resulting in serious injury to

yourself or bystanders.

• Inspect the blade periodically for wear or

damage.

• Always replace a worn or damaged blade.

3. Inspect the cutting edges of all blades. Sharpen the

cutting edges if they are dull or nicked. Sharpen only

the top of the cutting edge and maintain the original

cutting angle to ensure sharpness

blade will remain balanced if the same amount of metal

is removed from both cutting edges.

4. To check the blade for being straight and parallel, lay

the blade on a level surface and check its ends. The

ends of the blade must be slightly lower than the center,

and the cutting edge must be lower than the heel of

the blade.

Note: This blade will produce good quality of cut and

require minimal power from the engine. By contrast a

(Figure

blade that is higher at the ends than the center, or if

cutting edge is higher than the heel, the blade is bent or

warped and must be replaced.

5. Install the blade, with sail facing away from the ground

when you are mowing, the anti-scalp cup, and blade

bolt.

6. Tighten the blade bolt to 115–149 N-m (85–110 ft-lb).

Checking the Blade Stopping Time

Service Interval: Before each use or daily

The blades of the cutting unit should come to a complete

stop in approximately 5 seconds after you shut down the

cutting unit engagement switch.

To verify this stopping time, have another person stand back

from the cutting units at least 6 m (20 feet) and watch a blade

on a cutting unit. Have the operator disengage the cutting

units and record the time it takes for the blades to come to

a complete stop. If this time is greater than 7 seconds, the

braking valve needs to be adjusted. Call your Toro Distributor

for assistance in making this adjustment.

Note: Make sure that the cutting-units are lowered onto a

clean section of turf or clean hard surface to avoid thrown

dust and debris.
