It is very possible to cut brush life by 50% if the
frame is not level. Running an unlevel brush is
jast like throwingmoney out the window. The
small amount of time spent leveling a brush
before sweeping is paed back many times over
in longer brush life.
As a general rule brush level should be checked
every day before operating.
Uneven brush wear can also be caused by
discharging material to the same side of the
brush all the time. Flipping the brush core end -
for - end a couple of times during the course of
the brush life can help alleviate this.
Improper ground speed not only damages the
brush bur also cores, chains, sprockerts, drive
lines and even frames.
A rotary sweeper sweeps with the flicking action
of the bristle. The brush can sweep material up
to 1/2 the diameter of the brush. If the ground
speed of the vehicle is too fast the material
piles in front of the brush because it cannot be
discharged. This plow effect is caused by bull -
dozing with the sweeper instead of sweeping,
this will causes a side thrust on the brush, core
and frame components.
This sideward thrust causes the bristles to flex
against the steel ring holding them. Eventually
this flexing will break the bristles off at the ring.
Always sweep at a high enough brush speed
and low enough ground speed to effectively
discharge the material being swept.
