PROBLEM
The mower cuts unevenly,
with significant height dif-
ference front to rear.
The actual grass cutting
height is not aligned with
the claimed height.
The mower does not mulch
properly.
There is excessive vibration.
There are grass or debris
remaining on the ground
after mowing.
Short running time of the
mower with included bat-
tery.
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. 32).
◾
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.
◾
The cutting blades are loose.
◾
The blades are bent.
◾
The mower deck is not leveled.
◾
The mower deck nuts are loosened on the
suspension linkage (see Fig. 32).
◾
The mower is set to cut too much grass at once.
◾
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.
◾
The blade speed is low.
◾
Grass conditions and cutting-height setting will
greatly affect the battery run time. The claimed
run time is based on a light load condition.
