MAIN SWEEPING BRUSH
The main sweeping brush is cylindrical and spans
the width of the sweeping assembly. The brush
sweeps small debris into the debris hopper.
The brush should be inspected daily for wear and
damage. Remove any string or wire found tangled
on the brush, brush drive hub, or brush idler.
Check the main brush pattern every time a new
brush is installed. The brush should be replaced
whenever the bristles measure 30 mm (1.25 in) or
less in length.
