Toro Timemaster 20199 - Manual (Page 22)

DANGER
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.
3. Check for bent blades; refer to
Checking for Bent Blades (page 22).
Checking for Bent Blades
1. Rotate the blades until they are positioned as shown

2. Measure from a level surface to the cutting edges
at locations A and B, (Figure 43), and record both
dimensions.
3. Rotate the blades so that their opposite ends are at
locations A and B.
4. 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 1/8 inch
(3 mm), the blade is bent and must be replaced;
refer to Removing the Blades (page 22) and
Installing the Blades (page 23).
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.
1. Use a block of wood to hold each blade steady and
turn the blade bolt counterclockwise as shown in
Figure 44.

2. Remove each blade as shown in Figure 45.
