2) Differential Lock Mechanism
● This machine is equipped with a dif
-
ferential lock mechanism. Use it when
caught in mud and the wheels are
spinning, even though the machine
is in 4WD. The differential lock works
only in 4WD.
●
Since lawns may be scraped while making turns with the differential lock ap
-
plied, set it to the "OFF" position before turning.
7-2 Collection Work
●
Perform collection work with the engine rpm set between 2,000 and 2,200 rpm.
●
Before beginning collection work, be sure to perform a safety check of the in-
tended operating area.
● Make sure there are no dangerous areas such as drop-offs or steep slopes.
● Make sure there are no obstacles, such as people, animals or vehicles, in the
operating area.
● Make sure there are no overhead obstacles, such as trees or power lines.
●
For safe operation, exclude dangerous areas and either remove obstacles or
people in advance or clearly indicate operating area boundaries with flags or
ropes to keep people from entering the area. Be sure to work safely and in safe
areas.

When performing collection work,
shift the brush up/down lever toward
Down
to collect on undulating ground.
When turning, shift the brush up/
down lever to

to raise the brushes.
● Stopping the machine on a lawn while the brushes are rotating and lowered may
damage the lawn. Raise and lower the brushes while traveling.
● While performing collection work, raise and lower the operating unit while the
