Removing The Broom From The Traction Unit; Adjusting The Downward Pressure Of The Broom - Toro 22415 Operator's Manual

Removing the Broom from the
Traction Unit
1. Start the engine and lower the broom to the ground or
onto a trailer.
2. Disconnect the hydraulic hoses; refer to you traction
unit manual for more information.
3. Swing the clamp levers up to release the loader arm
clamps.
WARNING
POTENTIAL HAZARD
• The loader arm clamps are spring loaded and
can propel the front legs up and forward at
great speeds when released.
WHAT CAN HAPPEN
• The front leg could strike you or a by stander
causing severe injury.
HOW TO AVOID THE HAZARD
• Ensure that you do not stand in the path of the
front leg and that all bystanders are clear of the
area.
4. Swing the clamps off of the loader arms.
5. Remove the front legs/clamp levers from the loader
arms.
6. Raise the broom about 6 in. (15 cm) off of the ground,
and install the front legs in front of the broom.
7. Lower the broom to the ground.
8. Disconnect the traction unit to the broom mount plate;
refer to you traction unit manual for more information.
Adjusting the Downward
Pressure of the Broom
Improper downward pressure can decrease broom life up
to 95% (depending on the incorrect amount of pressure).
A broom sweeps with the tips of its bristles. When too
much down pressure is applied, the broom is no longer
using it's tips; the broom is now working with the sides of
the bristles. This limits the flicking action of the bristles
and limits it's sweeping effectiveness.
To check for correct downward pressure, operate the
broom on the ground, rotating at normal operating speed
with traction unit remaining stationary. Stop and raise the
broom. Measure the width of swept area (Fig. 10). A
properly adjusted broom will have a sweeping path width
of 2 to 4 inches (5 to 10 cm).

Adjust castor height for proper broom ground pressure.
The castor wheel height is adjustable from 4 to 7 inches
(10 to 18 cm) in 1/2 inch (1.2 cm) increments by adding
or removing an equal amount of spacers from each castor
wheel.
1. Start the engine and raise the broom.
2. Stop the engine.
3. Remove the cap securing the castor spindle to the
frame bracket (Fig. 11).
4. Move desired amount of spacers to the top or bottom
of the bracket (Fig. 11). Ensure that the spacers are
equal on both castor wheels and that a thrust washer is
positioned on each side of the frame bracket.
5. Install the cap and lower the broom (Fig. 11).
