CAUSE
◾
The blades are dull.
◾
The blades are bent.
◾
The mower deck is not leveled, resulting in
different cutting blade height.
◾
The mower deck nuts are loosened on the
suspension linkage (see Fig. 21c).
◾
The mower deck is damaged or seriously worn.
◾
Wet grass clippings are sticking to the underside
of the deck.

◾
The mower is set to cut too much grass at once
when the grass is tall.
◾
The grass is wet.
◾
The driving speed is high.

◾
Lawn terrain, grass conditions, cutting-height
setting, driving speed, blade speed, etc. will
greatly affect the running time.
SOLUTION
◾
Sharpen or replace the cutting blade as instructed in
this manual.

MOWER DECK" to have mower deck replaced.
◾
Wait until the grass dries before mowing.
◾
Raise the deck cutting height.
◾
Tighten the blade bolt to the recommended torque
36-41 ft-lb (50-55 Nm).
◾
Replace the bent cutting blade following the

lower cutting heights.
◾
Do no mow when the grass is wet until the grass
dries.
◾
Slow down the driving speed.
◾
Increase the blade speed gradually.
