RECOMMENDATIONS FOR MOWING
4.12 
Do not mow with dull blades. A dull blade will tear 
1. 
grass, resulting in poor lawn appearance and 
reduced mowing power.
 WARNING
DO  NOT  operate  without  Discharge  Chute, 
Mulching  Kit,  or  entire  Grass  Catcher  properly 
installed.
The discharge chute must not be removed and 
2. 
must be kept in the lowest position to deflect grass 
clippings and thrown objects downward. Direct the 
side discharge away from sidewalks or streets to 
minimize cleanup of clippings. When mowing close 
to obstacles, direct the discharge away from the 
obstacles to reduce the chance of property damage 
by thrown objects.
Cut grass when it is dry and not too tall. Do not cut 
3. 
grass too short (cut off 1/3 or less of existing grass 
for best appearance). Mow frequently.
Keep mower and discharge chute clean.
4. 
When mowing wet or tall grass, mow the grass twice. 
5. 
Raise the mower to the highest setting for the first 
pass and then make a second pass to the desired 
height.
Use a slow travel speed for trimming purposes.
6. 
Operate the engine at full throttle for best cutting. 
7. 
Mowing with a lower RPM causes the mower to tear 
the grass. The engine is designed to be operated at 
full speed.
Use the alternate stripe pattern for best lawn 
8. 
appearance. Vary the direction of the stripe each 
time the grass is mowed to avoid wear patterns in 
the grass.
ADJUSTING CUTTING HEIGHT
4.13 
The mower deck can be adjusted from a height of 1.0 inch 
to 6.0 inches at 1/4-inch intervals. To adjust the cutting 
height:
 WARNING
DO NOT adjust the cutting height with the mower 
blades rotating. Disengage the power to the cutter 
blades and then adjust cutting height.
Disengage the power to the cutter blades.
1. 
Push the cutting height adjustment foot pedal all 
2. 
the way forward using your right foot until it locks in 
place. See Figure 4-5.
